I'm testing a Cluster wizard migration from server 2012 to 2012R2 (Copy Cluster Roles in Server2012R2). For the most part everything is working except for the VMM/DPM integration. DPM can not find the VM and errors out. If I stop the protection and re-protect the server in DPM its fine, however it creates it as a new entity and will essentially double the disk requirements for backup. Worst yet, is that I plan to upgrade the cluster I'm moving from and then copy the roles back over once it is R2 (tripling the amount of storage needed 30TB or so)
The Migration wizard is much more efficient for us versus doing the Live migration through VMM to another cluster. We can afford the minimal outage.
Anyone else run into this scenario?
