Best Google Workspace Migration Software 2026: Expert Reviews, Comparisons & Buying Guide

Choosing a Google Workspace migration tool is harder than it looks, because the tools in this category are not interchangeable. Some move Gmail beautifully and ignore Google Drive entirely. Some handle Drive and SharePoint but won’t touch mailboxes. A few cover Google Vault; most don’t. Pick the wrong one and you discover the gap halfway through a migration weekend, which is the worst possible moment to find out.

This guide compares the 9 best Google Workspace migration software platforms in 2026 — EdbMails, CloudM, BitTitan MigrationWiz, Cloudiway, Kernel, SysTools, ShareGate (Workleap), AvePoint Fly, and Microsoft Migration Manager — on the things that actually decide a migration: which workloads each one really supports, what it costs at your user count, how much technical skill it demands, and where each falls short.

Every tool below has been assessed against its vendor’s own published capability documentation, not marketing copy. Where a tool doesn’t support a workload, we say so plainly — including for tools we rate highly.

How We Evaluated These Tools

Transparency about method matters more in this category than in most, because vendor marketing routinely overstates workload coverage. Here’s how the assessments on this page were put together:

• Capabilities are checked against vendor documentation, not marketing pages. Every “Yes/No/Partial” in the feature table reflects what each vendor documents its product as doing in its own knowledge base, admin guides or marketplace listing — not a claim from a landing page or a third-party summary. Where a tool doesn’t support a workload, we say so plainly, including for tools we rate highly.
• Pricing is drawn from published sources where they exist, and marked “quote-based” where they don’t. Figures come from vendors’ own pricing pages (for BitTitan and ShareGate) and from established software-listing platforms for tools that don’t publish rates. Quote-based tools are labelled as such rather than given invented numbers. See the pricing disclaimer and sources below for detail.
• Review scores are read alongside review volume. A high average on a small number of reviews is treated as a weaker signal than a slightly lower average on a large one, and we flag where a tool’s rating rests on a thin review base.
• Recommendations are workload-driven, not ranking-driven. No tool is “best” for everyone. The guide points different situations to different tools — including free and rival paid options — based on what each project actually needs.
• This site earns affiliate commission on some tools, including EdbMails. That funds the site but doesn’t buy a placement or a rating; the limitations sections apply to affiliate products the same as any other. See our affiliate disclosure.

How to Choose the Right Google Workspace Migration Tool in 2026 – Buying Checklist

Before you start comparing features and pricing, get clear on what you actually need. Use this checklist to filter out tools that won’t work for your situation before you waste time on trials:

• What data types are you migrating? Gmail and calendars are the baseline — but what about Google Drive files, Shared Drives, Google Vault archives, Google Chat history, contacts, and tasks? Not every tool handles all of these, and several handle none of the file-based workloads at all.
• How many users and mailboxes? A 15-person company and a 1,500-person enterprise have very different needs. Check whether the tool supports concurrent/parallel mailbox migration, and whether pricing scales reasonably at your volume.
• Do you need zero downtime? True incremental (delta) migration lets you pre-migrate data over days or weeks, then cut over with only minutes of disruption. If your team can’t afford downtime, this is non-negotiable.
• What’s your technical skill level? Some tools require PowerShell scripting, Google API configuration, and significant technical expertise. Others walk you through everything via a GUI with no scripting required. Be realistic about your team’s capacity.
• Do you need Google Drive / Shared Drive migration? This is the single most common mismatch. Migrating Gmail is one task; migrating Drive — with folder structures, sharing permissions, and version history — into OneDrive and SharePoint is a completely different capability. Confirm it explicitly, in the vendor’s own documentation, before you buy.
• Are you migrating Google Vault archive data? Most tools skip Vault entirely. If you have compliance archive data in Google Vault that needs to land in Microsoft 365, check this capability specifically — and don’t confuse it with migrating to a Microsoft 365 archive mailbox, which is a different thing.
• Does Google Chat or Spaces history need to move to Teams? Chat migration is a newer requirement most tools don’t document. If years of team conversations live in Google Chat and Spaces, verify Teams migration support explicitly — it’s rare in this category.
• What compliance certifications do you need? Regulated industries need ISO 27001, GDPR, HIPAA BAA, or SOC 2. Confirm the tool meets your requirements before committing.
• Is modern authentication (OAuth 2.0) supported? Microsoft has fully deprecated basic authentication. Any tool still relying on it is a security risk — and will stop working. OAuth 2.0 support is mandatory in 2026.
• What does support look like during a live cutover? Cutovers often happen at nights or weekends. You need live human support available when things get critical — not a ticket queue with a two-day response time.
• Is there a free trial or demo migration? The only real way to evaluate a migration tool is to run it on your actual data. Look for tools that let you test on real mailboxes before you spend anything.

Work through this checklist honestly before you evaluate any tool. It’ll cut your shortlist in half before you’ve read a single product page.

Quick Comparison: Best Google Workspace Migration Software 2026

Here’s a fast-reference overview to help you start narrowing down your options:

The most important column there is the first one. Several of these tools are mailbox specialists, several are file/collaboration specialists, and only a few span both — and a lot of failed migration projects come from assuming a tool covers everything. Read the detailed reviews below with your own workload list in hand.

Whichever scenario you land in, the advice at the top holds: run a free trial or demo migration on your real data before you commit. A test on a handful of actual mailboxes reveals more than any comparison table can.

Detailed Reviews: Top 9 Google Workspace Migration Software Platforms in 2026

1) EdbMails – Google Workspace Mailbox Migration

EdbMails is our top pick for the mailbox side of a Google Workspace migration, and it’s important to be precise about what that means. The EdbMails G Suite Migration Tool moves Gmail emails with full folder structure, contacts, calendars, tasks, attachments, and metadata — to Microsoft 365, to on-premises Exchange Server, or to any IMAP-supported destination. It does not migrate Google Drive, Shared Drives, or Google Vault. If those are in scope for your project, you’ll need a second tool alongside it.

Within that scope, it performs strongly, and the destination flexibility is a real differentiator. Most competitors in this list only migrate to Microsoft 365. EdbMails handles three destination platforms from one licence — which matters if you’re moving to a hosted Exchange environment, consolidating onto a non-Microsoft IMAP platform, or running a mixed estate. On the Microsoft 365 side, it migrates into primary mailboxes, shared mailboxes, archive mailboxes, and public folders, so the awkward edge cases most tools ignore are covered.

The way EdbMails connects to Google Workspace is worth understanding, because it matters for both security and administrative effort. The platform uses domain-wide delegation via Google’s secure API — your Google Workspace administrator grants controlled, authorised access to organisational mailboxes, and individual users never need to share credentials. On the Microsoft 365 side it connects using OAuth 2.0 modern authentication only, with no legacy basic auth fallback. This is the setup enterprise security teams and compliance auditors expect to see.

Incremental (delta) migration is the capability that matters most in practice. Rather than one high-risk overnight cutover, you start migrating days or weeks ahead while users carry on working in Google Workspace. EdbMails copies everything across in the background, and at cutover only the new or changed items since the last sync need to transfer — often just a few hours’ worth of mail. Downtime drops from hours to minutes, with no duplicates created and nothing missed.

The automation removes a lot of manual preparation. EdbMails automatically maps mailboxes between the source Google Workspace domain and the target tenant, and where target accounts don’t exist yet it can create them and assign licences — no CSV imports, no console work. On a migration involving hundreds of users, this alone can save a full day of setup.

Microsoft 365 API throttling is handled automatically: EdbMails monitors API response signals in real time and adjusts throughput to stay within limits, so migrations complete on large tenants that would stall tools with less capable throttle management. Filtering is equally practical — you can scope migrations by date range, sender, folder, or subject, so organisations with large mailbox histories but modest destination storage can migrate only what’s actually needed.

On compliance, EdbMails holds ISO 27001:2013 certification and is GDPR-compliant, with SSL/TLS encryption in transit, multi-factor authentication support, and exclusive use of documented Google and Microsoft APIs. User reviews across Capterra, G2, and GoodFirms consistently highlight data integrity, preserved folder structures, and responsive support.

EdbMails also offers a free demo migration against your real Google Workspace and Microsoft 365 environments on a subset of mailboxes — a genuine migration test on your own data, not a sandbox demo, so you can verify fidelity before purchasing.

Bottom line: if your Google Workspace migration is mailbox-centric — email, contacts, calendars, tasks — EdbMails is the tool we’d start with, particularly if your destination is Exchange or IMAP rather than Microsoft 365. Pair it with a file-migration tool if Drive is also in scope.

2) CloudM Migrate

CloudM is a SaaS platform with a strong reputation specifically in the Google Workspace migration space, and it’s the most complete single-tool option for organisations that need mailboxes and files handled together.

CloudM Migrate supports over 20 source platforms, but Google Workspace is clearly where the product feels most at home. It migrates Gmail to Exchange Online, Google Drive and Shared Drives to OneDrive for Business and SharePoint, Google Calendar to Outlook (preserving recurring events and reminders), contacts, tasks, and Google Vault archive data to Microsoft 365 Online Archives. The pre-migration environment scan is genuinely useful — it analyses your Google Workspace setup before migration begins and flags data volume problems, permission complexities, or file types that may not convert cleanly, giving you a chance to address them before they become mid-migration fires.

The interface is clean and well-designed for a non-specialist audience. MSPs in particular praise how quickly they can spin up new migration projects without reconfiguring from scratch each time. Support is described as responsive in most reviews, though some users note that issues during complex migrations can take longer to resolve than expected.

Where CloudM falls slightly short is the depth of its Microsoft 365 destination handling — SharePoint site architecture and Teams migration are less robust than dedicated tools, which matters if you have a significant SharePoint presence. Pricing also needs attention: at least one Capterra reviewer reported that licensing details weren’t fully clear during the sales process, leading to unexpected additional licence purchases mid-project. Get the full pricing breakdown in writing for your specific user count and workload mix before signing.

3) BitTitan MigrationWiz

BitTitan MigrationWiz has been around long enough to have moved a very significant portion of the world’s cloud email. It’s the default choice for a large part of the MSP community, partly because of its pay-per-mailbox pricing (around $14 per user for the Mailbox licence, or roughly $17.50 per user for the bundle that adds Drive and document migration) which fits project-based client billing neatly, and partly because of its genuinely simple, wizard-driven interface.

For migrations involving primarily Gmail, calendars, contacts, and basic Drive files, MigrationWiz performs reliably with a long track record behind it. The pre-stage migration option moves the bulk of data ahead of the cutover window, and batch processing makes it practical for MSPs running multiple client migrations simultaneously.

The limitations appear as complexity grows. SharePoint migration support is notably weaker than dedicated tools — metadata handling, permissions, and complex document library structures are consistently reported as shortcomings. There’s no native coexistence capability, so organisations needing GAL sync or mail routing between Google Workspace and Microsoft 365 during a staged migration need to look elsewhere. Google Vault is not supported. And support has been flagged repeatedly in user reviews as a pain point for complex issues, particularly for customers not on enterprise support tiers.

4) Cloudiway

Cloudiway is a fully cloud-based platform that has quietly earned a reputation as one of the most technically complete migration solutions available — particularly for complex scenarios involving Google Vault, coexistence requirements, and phased multi-workload migrations.

What Cloudiway does that most tools don’t is built-in coexistence. During a staged migration where some users are on Google and others have already moved to Microsoft, Cloudiway provides GAL synchronisation and mail routing so the two platforms behave as one. Users on both sides see each other in the directory and exchange mail without friction. For large or complex organisations where a big-bang cutover isn’t viable, this is genuinely valuable and hard to replicate.

Cloudiway also supports Google Vault migration to Microsoft 365 Online Archives — a capability many competing tools simply don’t have. If your organisation uses Vault for compliance archiving and needs that historical data preserved in Microsoft 365, Cloudiway is one of the few options that handles it natively.

The trade-off is a steeper learning curve. It’s best suited to IT teams or MSPs with migration experience rather than first-time administrators. Pricing is consumption-based and requires a scoped quote. For straightforward migrations it’s more tool than you need — but for genuinely complex projects it’s among the most capable platforms available.

5) Kernel Google Workspace to Office 365

Kernel (from Nucleus Technologies) is a Windows-based migration tool that covers a broader workload spread than most desktop products in this category — and it earns its place on this list for one capability in particular that almost nothing else here documents: migrating Google Chat and Google Spaces history to Microsoft Teams.

On the mailbox side, Kernel migrates Gmail emails, contacts, calendars, and tasks to Microsoft 365, with destination support for primary mailboxes, Office 365 Groups, archive mailboxes, shared mailboxes, and public folders. It also migrates Google Groups to Microsoft 365 Groups, including group email content, and its Drive module moves Google Drive files, folders, and shared files to OneDrive with metadata and permissions. Mailboxes can be added in bulk via CSV, automatic mapping matches source and destination accounts, and incremental migration prevents duplicates across repeated runs. Date and item-type filters allow selective migration, and OAuth-based authorisation is used for both platforms.

The Chat and Spaces migration is the standout. Organisations that have used Google Chat for years accumulate real institutional knowledge in those conversations, and most migration tools simply abandon it. Kernel documents migration of messages, images, documents, and metadata from Google Chat to Teams chat, and Google Spaces to Teams — with a split option for migrating Spaces data across multiple runs. If this workload matters to you, Kernel belongs on your shortlist regardless of what else you choose.

The honest limitations: it’s a Windows desktop application rather than a SaaS platform, so you’re running the migration from a machine you manage — which some teams prefer for data control, and others find less convenient than cloud tools. Google Vault is not supported, there’s no coexistence capability, and on-premises Exchange or IMAP destinations aren’t covered by this particular product. Pricing is quote-based, and the free demo is limited to a small sample of items per mailbox — enough to verify fidelity, not to migrate anything meaningful for free.

6) SysTools Migrator (G Suite to Office 365)

SysTools Migrator is a straightforward, competitively priced option for organisations whose migration is essentially mailboxes plus Drive documents, with Microsoft 365 as the destination. It won’t win a feature-count contest against the enterprise platforms, but for the most common SMB migration shape it covers the essentials competently.

The tool migrates emails, contacts, calendars, and Google Drive documents from Google Workspace to Microsoft 365, supporting concurrent migration of multiple user mailboxes in batch mode. Delta migration is documented — repeat runs move only new or changed items, avoiding duplicates — and date and category filters allow selective transfers, which is useful when only recent data needs to move. A priority option lets you push specific users to the front of the queue, real-time progress tracking shows migration status per account, and detailed plus summary reports document the outcome for sign-off. Authorisation uses OAuth 2.0, and no PowerShell is required at any stage.

Where it sits below the bigger platforms: Shared Drive migration into SharePoint isn’t a documented strength, Google Vault and Chat aren’t supported, there’s no coexistence capability, and destinations other than Microsoft 365 aren’t covered. Support quality in user reviews is generally described as responsive for standard issues, though this isn’t a vendor with the enterprise support depth of an AvePoint or CloudM. For a mid-sized migration with a modest budget and a simple workload list, though, it’s a legitimate contender — trial it against BitTitan and compare per-user costs at your volume.

7) ShareGate (Workleap Migrate)

ShareGate — now part of the Workleap family — is a SharePoint and Microsoft Teams migration specialist. It earns its place here not because it migrates Gmail, but because many Google Workspace migrations involve substantial SharePoint work on the destination side.

If you’re moving Google Drive and Shared Drives into a well-structured SharePoint Online environment with proper metadata, term stores, and permission hierarchies, ShareGate’s inventory, assessment, and migration tooling is among the most polished available. The drag-and-drop interface for managing SharePoint structure, combined with pre-migration reports that flag permission conflicts and content type issues before anything moves, makes it far more approachable than most SharePoint tooling.

The limitation is that ShareGate doesn’t handle Gmail or calendar migration at all — that part of your project needs a separate tool. It’s also a desktop application rather than pure cloud SaaS, which can constrain cloud-first environments or MSPs working remotely. On pricing, ShareGate Migrate uses flat annual tiers based on machine activations rather than per-user fees — Essentials, Pro and Enterprise — with unlimited users and data; note that pulling directly from a Google Workspace source requires the Pro tier or above, so budget accordingly if you’re using it to move Drive content rather than only restructuring the SharePoint destination. Treat ShareGate as the right tool for the SharePoint layer, not an end-to-end solution.

8) AvePoint Fly

AvePoint Fly is the enterprise end of the market — a cloud migration platform from one of the largest Microsoft 365 ISVs, bundled within a broader suite covering governance, compliance, backup, and lifecycle management. For large regulated organisations that want migration and post-migration governance from one vendor, AvePoint presents a compelling long-term story.

In a Google Workspace context, Fly handles the full workload spectrum: Gmail, Google Drive, Shared Drives, Calendar, contacts, and Vault. Pre-migration assessment tooling is enterprise-grade, generating detailed inventory and risk reports before anything moves. Audit trail and reporting capabilities meet heavily regulated requirements, and the broader platform means the same vendor can handle ongoing governance and retention once migration completes.

The honest drawback is that AvePoint is built for large IT teams or specialist implementation partners, not IT generalists running a first migration. The learning curve is real, and pricing requires custom engagement with sales. For organisations that genuinely need the governance story and have the resources to deploy it properly, it’s worth evaluating. For everyone else, CloudM or a mailbox tool paired with ShareGate will deliver better value.

9) Microsoft Migration Manager (Free)

Microsoft Migration Manager comes up in every Google Workspace migration conversation — it’s free, built into the Microsoft 365 Admin Center, and Microsoft has invested in improving it. For organisations on a tight budget with a simple migration, it’s a legitimate starting point.

The workflow involves connecting to Google, running a scan and assessment, adding drives to the migration list, reviewing destination paths, mapping identities, then running and monitoring the migration. Microsoft has made this reasonably approachable for Gmail and Drive, and it has improved considerably since early versions.

Where it falls short is depth and reliability at scale. Gmail label-to-folder mapping is inconsistent. Drive permission fidelity isn’t always maintained. There’s no incremental/delta migration in the same class as dedicated tools, so cutovers carry more risk. Google Vault is not supported. And there’s no phone or chat support — if something goes wrong, you’re in documentation and community forums. For a ten-person company it may be sufficient; beyond a few dozen users, meaningful Drive complexity, or any compliance requirement, a dedicated tool saves significant time and risk.

Pricing Comparison: Google Workspace Migration Software 2026

Pricing Disclaimer & Sources

Where each figure comes from:

• Published vendor pricing: EdbMails ($299 per 100 mailboxes, ~$2.99/mailbox, lifetime licence), BitTitan MigrationWiz (per-user Mailbox and Mailbox + Documents bundle rates) and ShareGate Migrate (flat annual Essentials / Pro / Enterprise tiers) all publish rates on their own sites, and those are the basis for the figures shown.
• Third-party listing platforms: CloudM Migrate’s per-user range reflects published estimates on established software-listing and procurement platforms, since CloudM prices per module and most buyers receive a custom quote after a scoping call.
• Quote-based vendors: Cloudiway, Kernel, SysTools and AvePoint Fly do not publish standard per-user pricing for these migrations. They are labelled “quote-based,” and you’ll need to request pricing directly for your user count and scope. The cost estimator excludes them rather than inventing a number — the disclaimer under it names who to contact.
• Free tools: Microsoft Migration Manager is included with Microsoft 365 at no additional licence cost; the real cost is administrative time and the absence of live support.
• Cost estimator method: the estimator multiplies your user count by the published per-user rates above (EdbMails, BitTitan, CloudM) and shows ShareGate as its flat annual entry tier, sorting cheapest first. Quote-based and free tools are excluded. It’s a licence-cost budgeting aid, not a quote — treat its totals as order-of-magnitude estimates, and note that EdbMails and BitTitan’s mailbox line are mailbox-scope while CloudM includes Drive.

Capability claims throughout this guide are checked against each vendor’s own published product documentation.

User Ratings on Major Review Platforms

Ratings below are indicative averages from the two largest independent software review platforms as of July 2026. Review volumes vary enormously between these products, and that matters more than the average itself: a 5.0 built on a handful of reviews is a weaker signal than a 4.5 built on several hundred. EdbMails is a case in point — its average is very high, but on G2 it rests on a smaller review base (roughly two dozen reviews, split across several separate EdbMails product listings), whereas CloudM and BitTitan carry far larger review counts. Kernel’s and SysTools’ Google Workspace migration tools have low review volumes on these platforms, so we’ve left their cells unscored. Treat every figure here as a starting point and check the live listings — including the review count — before you weigh any of them.

Google Workspace Migration Scenario Guide – Which Tool Fits Your Situation?

Tool Capabilities That Prevent the Most Common Migration Problems

• Gmail labels producing duplicate folders: Gmail lets one email carry several labels; Outlook puts each message in one folder. Ask specifically how a tool maps multi-labelled mail — good ones let you control whether duplicates are created.
• Google Docs format fidelity: Docs, Sheets and Slides convert to Office formats during a Drive migration. Conversion is generally accurate but imperfect for complex formatting and embedded scripts. Any tool you shortlist for Drive should let you test on a sample first.
• Shared Drive permissions: Google’s permission model doesn’t map cleanly to SharePoint. Look for pre-migration reporting that flags permission conflicts before anything moves — ShareGate and AvePoint lead here.
• Abandoned Chat history: Years of decisions and context live in Google Chat and Spaces, and most tools silently leave it behind. If it matters, plan for it explicitly — Kernel is the documented option in this guide.
• Cutover data loss: Without true delta sync, anything arriving during the migration window is at risk. Confirm the tool performs a genuine final incremental pass, not a full re-run.
• Throttling stalls on large tenants: Microsoft 365 API limits will stop a naive migration mid-run. Automatic throttle management is worth more than raw advertised speed.
• Scope discovered too late: The costliest problem is realising mid-project that your tool doesn’t cover a workload. Audit everything first — suspended accounts, Shared Drives, Vault archives, Chat history, groups, service accounts — then match the tool to that list.

Emerging Trends in Google Workspace Migration Software (2026 and Beyond)

• AI-assisted migration planning: Platforms are embedding AI-driven pre-migration analysis that identifies data risks, permission conflicts, and format compatibility issues automatically — catching problems before they become mid-migration crises.
• Chat history as a first-class workload: As organisations accumulate years of institutional knowledge in Google Chat and Spaces, migrating conversations to Teams is shifting from a nice-to-have to a formal project requirement — and tool support is only beginning to catch up.
• Drive-to-SharePoint architecture planning: Organisations are investing more thought in how Drive content maps to a properly structured SharePoint and OneDrive architecture, rather than a flat lift-and-shift that recreates Drive’s informal structure.
• Copilot readiness driving urgency: Microsoft 365 Copilot needs a well-structured, well-governed environment to deliver value, and is unavailable in Google environments — which is accelerating some migration timelines.
• Compliance-first tooling: Stricter data protection rules are making data residency, retention policy transfer, and audit trail preservation core selection criteria rather than afterthoughts.
• Long-term coexistence: Some organisations aren’t doing a clean switch but maintaining both platforms for different user populations, making sustained coexistence support more valuable than one-time migration speed.

Final Recommendations – Which Google Workspace Migration Tool Should You Choose in 2026?

• Best for mailbox migration: EdbMails — the most capable, straightforward option for email, contacts, calendars and tasks, and the most flexible on destination (Microsoft 365, Exchange, or IMAP), with a free real-data demo migration.
• Best all-in-one (mail + files): CloudM Migrate — the strongest single-product coverage of mailboxes, Drive, Shared Drives and Vault together.
• Best for Google Chat & Spaces to Teams: Kernel — the only tool in this guide that documents Chat and Spaces history migration to Microsoft Teams, alongside mailbox, Groups and Drive coverage.
• Best budget mailbox + Drive documents option: SysTools Migrator — the essentials (delta migration, batch processing, filters, OAuth 2.0) at per-user pricing without platform overhead.
• Best for MSPs: EdbMails or BitTitan MigrationWiz — per-mailbox pricing that fits project billing, with fast repeat project setup.
• Best for complex coexistence: Cloudiway — built-in GAL sync and mail routing for staged migrations where both platforms run side by side.
• Best for the SharePoint layer: ShareGate (Workleap) — pair with a mailbox tool; unmatched for SharePoint structure and permissions.
• Best for large regulated enterprises: AvePoint Fly — full workload coverage plus governance, retention and audit tooling from one vendor.
• Zero budget option: Microsoft Migration Manager — free and functional for small, simple moves; accept the limitations going in.

Start with a free trial or demo migration on your actual data — most of these platforms can be evaluated within a business day.
