M365 GCC High to M365 Commercial migration
Thank you for the question garyrhoward
We recently went through this with a small city client. We went back and forth with Microsoft support for months. (They are SO slow to respond). There is no supported migration to convert an existing tenant.
From what I was able to glean from Microsoft's replies, it sounds like the GCC low & GCC high tenants reside on different servers than commercial tenants. So, they can't just be changed to a different status.
In the end we created a new 365 commercial tenant and used a 3rd party migration tool (BitTitan) to move/copy the users Mailboxes & OneDrives over to the new tenant.
SabersKiss many thanks for the reply, was very helpful. My customer's intent is to create a new M365 Commercial tenant too then copy the data. Did you encounter any challenges/ unsupported scenarios performing the copy from the GCC tenant? Apart from Mail, OneDrive we have Teams workload too.
Regards,
Ravi- Not really, but the client wasn't utilizing much of the 365 features, so it's probably not a fair comparison. They were in GCC Low, and they only used email, OneDrive, and Teams chat. Literally it was only four users to move.
The hardest parts for us was licensing both tenants for the transition. (We use Pax8 for licensing.) We had to open a second support ticket with Microsoft to buy GCC licenses direct in the old tenant to keep things going while we changed the linked tenant in Pax8 to buy the licenses for the Commercial tenant.
We had a little trouble with BitTitan's migration, but that was just normal authentication issues.
I'm not aware of a way to migrate things like PowerBI, or Planner Plans, Forms, etc. Those could be a nightmare.
