For administrators that have provisioned an RMS account, Cloud App Security allows you to migrate to a Microsoft Information Protection (MIP) account for enhanced protection provided that you have one of the following licenses which include a MIP service plan:
Microsoft 365 E5/A5/G5/E3/A3/G3/F1/F3/Business Premium
Microsoft 365 E5/A5/G5/E3/A3/G3/F1/F3/Business Premium
Enterprise Mobility + Security E3/E5
Office 365 E5/A5/E3/A3/F3
Azure Information Protection Plan 1
Azure Information Protection Plan 2
The Migrate to Microsoft Information Protection Account screen appears.
If an authentication error occurs, you can still click Done to only remove the RMS account from Cloud App Security. This does not remove the RMS account from your Office 365 services.
After the process is completed, the RMS account changes to a MIP account.
