How to Migrate a SharePoint Online Site to Another Tenant
Question details
The user needs to move SharePoint Online sites, data, and workflows from one organizational tenant to another.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Performing a tenant-to-tenant migration of SharePoint sites, requiring domain, identity, and service dependencies to be properly handled.
- Observed behavior
- The migration requires specific permissions, identity mapping, and a structured migration method to safely transfer complex environments without data loss.
Verify that you have Global Administrator or SharePoint Administrator permissions in both the source and destination Microsoft 365 tenants.
Use Microsoft FastTrack and Support Guidance
The recommended approach for complex, business-critical migrations to ensure data integrity and workflow continuity.
A tenant-to-tenant migration involves complex dependencies like domain transitions, identity mapping, and user permissions. For most organizations, leveraging Microsoft's official cross-tenant migration support is the safest route.
Access the Microsoft Learn portal and review the cross-tenant SharePoint site migration documentation to understand current prerequisites and limitations.
Ensure the target tenant has sufficient SharePoint storage quota and that all required user identities have been provisioned.
Have your Microsoft 365 administrator log into the Microsoft 365 Admin Center, navigate to the Support tab, and open a ticket requesting cross-tenant migration assistance.
If your organization has 500 or more eligible licenses, request data-migration guidance and onboarding support directly through the Microsoft FastTrack program.
Manual Migration for Small Document Libraries
A basic, manual approach suitable only for very small sites that primarily store standalone files, without complex workflows or metadata.

Frequently Asked Questions
Will I lose my file version history during a tenant-to-tenant migration?
If you use Microsoft's official cross-tenant migration tools or enterprise third-party tools, version history and file metadata are typically preserved. However, manual download and upload methods will lose version history entirely.
Can I migrate SharePoint workflows automatically to the new tenant?
Most Power Automate flows and native SharePoint workflows cannot be automatically migrated using standard site migration tools. They typically need to be exported and re-imported manually or recreated, as they rely on tenant-specific identities and connections.
How do I handle user permissions when migrating to another tenant?
You must perform an identity mapping process. This links users in the source tenant to their corresponding accounts in the destination tenant. If a user does not exist in the destination tenant, their historical permissions cannot be accurately migrated.
Do I need a third-party tool for SharePoint migration?
While Microsoft provides built-in tools and FastTrack support for cross-tenant moves, many organizations choose third-party tools (like ShareGate or AvePoint) for their user-friendly interfaces, pre-migration reporting, and advanced scheduling capabilities.
