After the Rollup 1 for SP1 we are having problems with 2 protection groups. During a rolling upgrade to Server 2012 we've moved a couple of VM's around and it seems that the a couple of VM's are in 2 protection groups at once. When we try to change the protection group we get :
Removing \Backup Using Child Partition Snapshot\SERVER1 failed: Error 157: Backup Using Child Partition\SERVER1 cannot be added to protection group because it is already a member of a protection group.
We've tried about everything but cannot seem to get it working again.
Anyone with bright ideas ?

Did you try the powershell way?
To remove a protection group member by using DPM Management Shell
Use the following syntax to remove a member from a protection group:
Remove-ChildDatasource -ChildDatasource <ProtectableObject> -ProtectionGroup <ProtectionGroup> [-PassThru] [-KeepDiskData]
For more information, type "Get-Help Remove-ChildDatasource -detailed" in DPM Management Shell.
For technical information, type "Get-Help Remove-ChildDatasource-full" in DPM Management Shell.
If you are moving vm's around maybe it's a good idea to check the combination between VMM and DPM in regards to live migration backups:
It's doing common things uncommonly well that brings succes.
