Veeam Backup for Microsoft 365 • Re: Cross-tenant restoring (migration)?

Hi Tim,

Welcome to the forum.
Cross-tenant restore is supported. However, I don't see how this would be feasible for SharePoint. For example, during a restore, SharePoint sites would lose their previous owners and configured permissions, because the new M365 tenant doesn't recognize the old user accounts.

I'd also like to add that our product is a Backup and Recovery application, not a migration tool.
Especially for Exchange migrations, I recommend researching purpose-built migration services or tools. There are many available—you can find several with a quick Google search. These services typically offer the ability to pre-sync entire mailboxes, including permission mappings. On the actual migration day, you only need to perform a final sync and then update DNS records and Outlook configurations to point to the new tenant. Such services can significantly reduce the amount of work required on migration day.

Best regards,
Fabian
