How do I maintain backups after moving VMs from a 2012 cluster to a 2012R2 cluster?

I've DPM2012 R2 and it was backing up VMs in a Win 2012 cluster. All good. New Windows 2012 R2 cluster created. Storage detached from existing nodes (iSCSI SAN) and presented to new nodes. Imported VMs, with both register (retain ID) and some copy (new ID). But if I want to back any of them up, it seems to see them all as new machines. I just want to continue on as nothing in the VMs have changed, just the name in DPM i.e. vm.oldcluster.domain whereas it's now vm.newcluster.domain. Any advice would be greatly appreciated.

Hi,

If you want DPM to be able to "follow" your VMs as they move across different cluster or stand-alone hosts you will have to run the Set-DPMGlobalProperty -KnownVMMServers YourVMMServer on your DPM-server protection the VMs.

Set-DPMGlobalProperty

DPM: Windows 2012 VM Mobility Uninterrupted Data Protection

Hope it helps!

Kind Regards
