Hyper-V 2012 -> 2012 R2 Cluster Migration Issues

Quick post more to document an oddity than anything…

Migrating machines from a 2012 cluster to a 2012 R2 cluster using VMM 2012 R2 with mixed results. In particular, I’m seeing the machines duplicated in Failover Cluster Manager – one of the two seems to be the live machine and the second, prefixed with SCVMM (as all VMM created machines are) seems to be broken with various errors such as ID 21502 “Missing or invalid virtual machine ID resource property”. Simply removing the duplicate starting with SCVMM and all seems to be ok.

Odd though.
