Why ShareGate

How tenant-to-tenant migrations work with ShareGate

The complete T2T migration—identity, mailboxes, and content—in one connected workflow.
ShareGate pre-migration analysis screen showing 2 warnings and 1 error, with an option to export a permissions matrix report.

Step 01

Map users. Surface issues. Fix them in bulk.

Scan your source tenant to surface identity gaps, permission conflicts, and issues before anything runs. Review and resolve them in ShareGate's planning view, then migrate Entra ID users and groups.
ShareGate drag-and-drop migration interface showing SharePoint and Teams as sources, with a checklist of migratable content including documents, site collections, Purview sensitivity labels, and shared mailboxes, with migration running in full throttle.

Step 02

Migrate every workload. In one tool.

With users ready and waiting in the destination tenant, mailboxes and content land in the right place. Run migrations across multiple machines to avoid Microsoft throttling.
ShareGate copy results screen showing migration outcomes by team — Marketing Team with 124 successes and 10 warnings, and Operation with 376 successes and 26 warnings — with an Export report button.

Step 03

A migration your organization barely notices

Users arrive with licenses. Permissions follow. Mailboxes and content reach the right people. Incremental passes catch changes made between waves. No one has to stop working while you finished the job.

Pre-migration planning

Scan your source tenant before anything moves. Surface identity gaps, permission issues, and content that needs cleanup. Then fix problems in bulk so your migration starts clean instead of inheriting the mess.

Prepare your migration
ShareGate Migrate pre-migration analysis screen showing a summary of 15 site collections, 85 sites, 8 errors, and 45 warnings, with a list of potential limitations including unsupported site templates and custom features flagged for review.

Accelerated migration

Run multiple machines simultaneously to move more mailboxes faster. The more machines you have, the more ground you cover. So large projects finish on schedule, not whenever throughput allows.

Post-migration optimization

Cutoverisn'tthe finish line. Keep permissions clean, access controlled, and yournew environmentrunning the way it should without bouncing between admin centers or writing PowerShell scripts from scratch.

Frequently asked questions

What’s the right sequence for a Microsoft 365 tenant-to-tenant migration?

The most important thing to set up in the destination tenant before you migrate mailboxes or content is users. Destination users need to exist and be licensed so that permissions land correctly and content reaches the right people from day one.

ShareGate now handles Entra ID migration, including identity prep and mapping. You can migrate Entra ID users, security groups, and Microsoft 365 Groups with licenses assigned as part of the migration itself, so users arrive ready for the next step without a manual licensing pass.

Custom domain mapping handles source-to-destination domain translation, even across complex multi-domain environments. And if the auto-matching doesn't fit your project, manual overrides let you take full control of any mapping decision.

Once identity migration completes, an automated first-login flow gets migrated users into their new accounts immediately. No IT hand-holding, no support queue.

The sequence matters. Get users right first, and mailboxes and content fall into place.

‍

How can I automate my tenant-to-tenant migration?

ShareGate can help automate your migration, save you time, and help to make sure your move is smooth. 

ShareGate makes migration simple with an intuitive interface and easy drag-and-drop functionality. You can automate user and group mapping, run incremental passes to sync what’s changed between waves, and centralized reporting across everyworkload, so you don’t have to bounce between admin centers. No PowerShell required, though if you want to script parts of the process, PowerShell is fully supported. The result: a migration you can run, monitor, and repeat without rebuilding it from scratch each time.  

Will our end users be able to keep on working during the migration process?

Yes! We know that most migrations don’t happen in one big push overnight. End users need to keep working while you plan and migrate content in batches.  
‍

ShareGate handles this with incremental migrations. After your initial migration, you’ll be able to copy only what’s changed. That applies across identities, mailboxes, and content, so you’re not re-migrating everything each waves or asking users to stop working while you catch up. 
‍

What are the most common T2T migration challenges, and how does ShareGate handle them?

Tenant-to-tenant migrations often fail because identities aren’t migrated properly before mailboxes move, permissions don't survive the transfer, throttling kills your timeline, and users keep working while you migrate, changing content between waves. 

ShareGate addresses all of these. Entra ID migration handles identity preparation first, so mailboxes, and content land where it should. Incremental passes sync only what's changed between runs, so ongoing work doesn't get lost. Concurrent migration across multiple machines keeps large projects on schedule despite Microsoft throttling. And permissions, metadata, and timestamps migrate alongside content, so you don’t have to deal with manual cleanup after cutover.

Which ShareGate plan includes tenant-to-tenant migrations?

ShareGate supports tenant-to-tenant migrations on any Migrate plan, but if you need to migrate Entra ID, Exchange Online or Google Workspace, you'll need Migrate Pro or Migrate Enterprise.

Can I use my ShareGate license to migrate multiple tenants or subsidiaries?

Yes, if the tenants are part of the same organization: tenants you own, are acquiring, or divesting. This typically covers subsidiaries and affiliates under the same corporate ownership. 

No, if you're a consultant or MSP trying to use one license across unrelated client tenants. Each client project requires its own license. 

What admin permissions do I need for tenant-to-tenant migrations?

The answer depends on the source:

  • Entra ID and Exchange Online: Global Admin permissions for both source and destination tenants 
  • SharePoint and OneDrive: Site Collection Administrator on the specific sites you're migrating andSharePoint Admin is only required if you want to browse the entire tenant or create sites during migration. 
  • Teams:SharePoint Admin plus Teams Admin (or Global Admin), and a Global Admin must grant one-time consent to ShareGate's Azure migration app.  
  • Google Workspace: Google Workspace Super Admin permissions to use administrator mode.
