Migrating Data to a new Tenant

[pmclean]

I have had a second tenant running for an acquisition for several months now and now its time to migrate the data from the old tenant to the new.

Would Veeam be a good choice for that? Could I simply do a Single-Event Migration by restoring a Veeam backup into the new tenant?

Not sure on the granularity I can get when restoring but I would want to restore all my Tenant A SharePoint sites into one single Tenant B SharePoint site (for archival purposes). \

I want to migrate all emails 1:1 (user1@tenanta.com > user1@tenantb.com).

Idk if I even need Teams information or not.

Or am I better off looking into a specialized solution for migrating tenants?

Hi Patrick

First, please let me say:
Veeam Backup for Microsoft 365 was build to protect and restore data. It is not a migration software.
If you are looking for Tenant migration, maybe better check out alternatives (applications, online services, Microsoft own migration services) which are build exactly for migration purposes.

As an example. For mailboxes, I would prefer a service which allows you to pre-sync 99% of all objects and then on the migration day only sync changed or new objects after you have reconfigured mx to the new tenant. It keeps the downtime for your users low.

To answer your question:
Migrating most of the data with VB365 is possible, but It's not a 1 click solution and probably must be scripted. Too many manual steps if not scripted.
SharePoint: A full restore of SharePoint data may take hours/days/weeks depending on how much data you have. Make sure the data was not encrypted with SharePoints encryption feature in the old tenant. The new tenant won't be able to decrypt it.
MS Teams data: cannot be restored to a new tenant.
Exchange Online: Restore should be scripted. Bulk restore of multiple mailboxes to another M365 tenants is not possible

Best,
Fabian

Hi Patrick,

I noticed your query about migrating data to a new Microsoft 365 tenant. While Veeam Backup for Microsoft 365 is an excellent tool for data protection and restoration, as Fabian mentioned, it might not be the best fit for migration purposes.

You might want to check out Medha Cloud's Office 365 migration services. They are partners with both Veeam and Microsoft, which could be beneficial for a seamless migration process. Their service is designed to handle the complexities of migrating to a new tenant, ensuring minimal downtime and efficient data transfer.

You can find more information about their services here: Office 365 Migration Services by Medha Cloud.

Hope this helps!
