When performing a tenant-to-tenant migration that includes a domain move, On Demand Migration needs to refresh the source and target usernames and email addresses after the domain move to ensure that the Desktop Update Agent works as expected. To use the Desktop Update Agent after moving a domain from one tenant to another, perform the following procedure:
- Complete the Domain Move.
- Confirm that the updated usernames and email addresses are shown in the source and target tenants.
- Re-run the New Account Discovery Task wizard to refresh source usernames and email addresses.
- Re-run the New Account Matching Task wizard to refresh target usernames and email addresses.
- Run the New Switch Applications Task wizard. Select the options to Skip mailbox state validation and Skip OneDrive state validation if the account migration states were reset to Matched. For more information, see Configuring the Switch Applications Task in the Desktop Update Agent User Guide.
|
|
NOTE: If you run the New Switch Applications Task before the domain move is complete, you will not need to re-run the task since the Desktop Update Agent will check the source and target user information at the time the end-user runs the tool. |
When the user accounts are matched or migrated, you can transfer the content of their OneDrive for Business stores to the target tenant.
Migration limitations indicated below may not be an exhaustive list of limitations as some may appear in unique customer migration scenarios, or arise due to platform or legacy support restrictions. In some cases, a solution to a limitation may already be on the product roadmap.

| Microsoft public preview features |

In general, Microsoft public preview features are not supported in production migrations. These features may also take additional time to fully develop and test for release to production. |
| Personal SharePoint Lists |
✖ |
|
| SharePoint subsites, lists and libraries added to a user's OneDrive |
✖ |
|
| Whiteboard |
✔ |
The folder that contains the Whiteboard files is migrated. If you plan to migrated Teams, you must pre-migrate the Whiteboard files created by the Whiteboard creator. |
Limitations
Only the latest version of frequently updated files such as outlook PST files, database files and log files will be migrated.
Considerations
Before starting the OneDrive migration consider the following:
- When active or expired Sharing Links are migrated, existing permissions are converted to direct permissions in the target tenant.
- Migrating Sharing Link permissions for external users requires the external user be an Azure Active Directory guest.
- Migrating Authors and Editors will only map to the Primary SMTP Address. Multiple SMTP addresses are not currently supported.
- Migrating a OneDrive user Recycle Bin is not supported.
- Document with URLs longer than 400 characters cannot be migrated to a target tenant.
- Very large OneDrives with hundreds of thousands of files or files that are 500 GB or larger, should be divided into two or more OneDrives to improve migration throughput.
