Step 6: Start a OneDrive cross-tenant migration

This is Step 6 in a solution designed to complete a Cross-tenant OneDrive migration. To learn more, see Cross-tenant OneDrive migration overview.

Now you're ready to start your OneDrive migration. Before starting any cross-tenant migration, do the following steps.

  1. Ensure you have verified the compatibility status. If you see a status of either Compatible or Warning on your source tenant, you can continue. Run:

    Get-SPOCrossTenantCompatibilityStatus –PartnerCrossTenantHostURL [Target tenant hostname]
  2. To start the migration, a SharePoint Online Admin or Microsoft 365 Global Admin of the source tenant must run the following command:

Start-SPOCrossTenantUserContentMove  -SourceUserPrincipalName <...> -TargetUserPrincipalName <...> -TargetCrossTenantHostUrl <...>
Parameters Description
SourceUserPrincipalName User principal name of the user who owns the OneDrive on the Source tenant.
TargetUserPrincipalName User principal name of the user who owns the OneDrive on the Target tenant.
TargetCrossTenantHostUrl The Cross-tenant Host URL of the target tenant. To find the TargetCrossTenantHostUrl, run Get-SPOCrossTenantHostUrl on the tenant.


Start-SPOCrossTenantUserContentMove -SourceUserPrincipalName -TargetUserPrincipalName -TargetCrossTenantHostUrl 

To Schedule a migration for a later time, you can use and append the above command with the one of the following parameters.

These commands can be useful when planning bulk batches of OneDrive migrations. You can queue/migrate up to 4,000 OneDrive migrations per batch. If your user count exceeds 4,000, create separate batches, and schedule them to run once the current batch is close to completion.

Parameter Description
PreferredMoveBeginDate The migration will likely begin at this specified time. Time must be specified in Coordinated Universal Time (UTC).
PreferredMoveEndDate The migration will likely be completed by this specified time, on a best effort basis. Time must be specified in Coordinated Universal Time (UTC).

OneDrive status pre-migration

Before starting the migration, the users current source OneDrive status is similar to the example below. This example is from the users source tenant, showing their current files and folders.

Cancelling a OneDrive migration

You can stop the cross-tenant migration of a user's OneDrive by using the following command, provided the migration doesn't have a status of In Progress, Rescheduled or Success.

Stop-SPOCrossTenantUserContentMove – SourceUserPrincipalName [UPN name of user who you wish to stop]


Stop-SPOCrossTenantUserContentMove – SourceUserPrincipalName

Determining current status of a migration

After starting your migration, you can check its status using the following command on either the source OR target tenant:

Source command format:

Get-SPOCrossTenantUserContentMoveState -PartnerCrossTenantHostURL [Target URL]


Get-SPOCrossTenantUserContentMoveState -PartnerCrossTenantHostURL

Target command:

Get-SPOCrossTenantUserContentMoveState -PartnerCrossTenantHostURL [Source URL]


Get-SPOCrossTenantUserContentMoveState -PartnerCrossTenantHostURL

To find the status of a specific user's migration, use the SourceUserPrincipalName parameter:

Get-SPOCrossTenantUserContentMoveState -PartnerCrossTenantHostURL <PartnerCrossTenantHostURL> -SourceUserPrincipalName <UPN>


Get-SPOUserAndContentMoveState -PartnerCrossTenantHostURL -SourceUserPrincipalName

To get the status of the move based on a particular user’s UPN but with more information, use the -Verbose parameter.


Get-SPOCrossTenantUserContentMoveState -PartnerCrossTenantHostURL -SourceUserPrincipalName -Verbose 

Migration States

Status Description
NotStarted The migration hasn't yet started.
Scheduled The migration is now in the queue and is scheduled to run when a slot becomes available.
ReadytoTrigger The Migration is in its preflight stage and will start the Migration shortly.
InProgress The migration is in progress in one of the following states:
- Validation
- Backup
- Restore
- Cleanup
Success The Migration has completed successfully.
Rescheduled The migration may not have completed and has been requeued for another pass.
Failed The migration failed to complete.

Post-migration status checks

Target tenant: After the migration has successfully completed, check the status of the user on the target tenant by logging into their new OneDrive account.

Source tenant: Since the user has successfully migrated to the target tenant, they no longer have an active OneDrive account on the source.
