GDPR Retention Label Removal

[Niek_Meerkotter]

We need to migrate a tenant to a new tenant. GDPR Labels have been running in OneDrive, SharePoint and Exchange.

If we migrate by using a program such as Move in O365 must the GDPR Label be switched off?

I it must be switched off - How long before we migrate?

I believe that all stored documents are now encrypted in OneDrive and SharePoint.

Any interference to be expected in Teams?

Yes any document you migrate to the new tenant should first be decrypted otherwise disruption will occur when accessing that content in the future.

For example:
- when the user's identity is migrated from the source tenant to the target tenant, for example, the UPN suffix (@domain.com) then the users won't be able to authenticate to open the AIP encrypted data
- if the source tenant is ever decommissioned then the AIP content will be unreadable.
- Probably several other scenarios too numerous to mention.

The Auto-Label policy doesn't have any setting of automatically removing encryption from all documents that it has applied to. This means if a user has downloaded a document to their local hard drive then you won't be able to decrypt that document.
