Frequently Asked Questions

Is there a Public Preview date for SharePoint cross-tenant migration?

As of now, Microsoft has not announced an official date for the Public Preview. The feature remains strictly in Private Preview for eligible Enterprise Agreement customers.

Why does the Set-SPOCrossTenantRelationship command keep failing?

This command usually fails if system prerequisites are unmet. Common causes include having Customer Key service encryption enabled on the source tenant, source sites being locked in read-only mode, or using an outdated version of the SharePoint Online Management Shell.

Can small businesses without an Enterprise Agreement use this migration tool?

Currently, cross-tenant user content migration and its associated licenses are exclusively available to Enterprise Agreement customers. Organizations without this agreement must use third-party migration tools or manual transfer methods.
