Admins: Migrating user data during mergers and restructurings just got easier

We’re excited to announce cross-tenant orchestrated user data migration, enabling a more seamless migration experience for organizations during mergers and restructurings. 

What’s new

Organizations going through mergers, acquisitions, divestitures, and internal restructuring often face a hard operational problem: How to move user data between Microsoft 365 tenants with minimal disruption to the people affected by the change. 

Previously, admins had to choose between fragmented point tools, increasing risk and making troubleshooting harder. Many of you asked for a Microsoft-native, orchestrated migration experience, and we’re thrilled to deliver one!

Now, admins can create migration batches through Graph APIs and move Exchange, OneDrive, Teams chats, and Teams meetings all from one workflow. You’re able to validate all prerequisites, such as licenses, identity mapping, and permissions, before committing to a migration date. And if validation fails, you can see the exact issues and fix them before trying again.  

Users will now experience an end-to-end migration built with them in mind. After their mailbox moves, their Teams meetings will be updated so they can use them seamlessly, without needing to manually cancel and reschedule. Teams chats will be migrated and support federation to continue collaboration between the source and target tenants. This product is integrated with the same fast mailbox and OneDrive migrations that customers have used for years.

Why it matters

With this update, admins can now: 

  • Speed up data migration, especially when there’s a time crunch to move staff over to your tenant. 
  • Reduce support ticket requests during migration. 
  • Fix quickly and prevent organization-wide failures that bog down productivity. 

How to get started

  1. Identify the workloads to move (e.g., mailboxes, OneDrive files and folders, Teams chats, and Teams meetings). 
  2. Prepare tenants and users with the required configurations. 
  3. Validate configurations using our API before migrating user data. 

Known limitations

  • This update is available in public cloud only.​​ 

Availability

This update is available to admins with a Global Administrator role for initial configuration, and a Microsoft 365 Migration Administrator or Global Admin role for later steps, with a Cross-Tenant User Data Migration add-on license per user.

    The main issue here is Entra and Intune enrolments.
    Having to unhash, reset the device, hash and re-enrole a device to a different tenant is a pain, where previously all we had to do for devices was move the device objects to a different OU in AD to get the correct GPOs.

    Where is SharePoint in this equation? Since you are doing OneDrive, it doesn't seem like SharePoint would've been a heavy lift; but without it present I'm guessing this will be a non-starter for most customers.

      Microsoft's SharePoint migration product is closely related to the OneDrive solution. The cross-tenant orchestrated user data migration product moves data that is exactly associated with a single user: their mailbox, their Teams, and their OneDrive. SharePoint Sites are shared amongst users, and can be moved using the standalone product in tandem with the user data.

        If you have an EA. Again, for most customers (especially as MSFT has driven companies away from EAs in the last few years), this will be a non-starter.
