Hi,
I am currently running a Hyper-V 2012 Server Cluster with 7 nodes and one CSV. I would like to know if its possible to upgrade the cluster to Hyper-V 2012 R2 without starting fresh and migrating virtual machines. I thought I had originally read somewhere that it is possible for me to live migrate all VM's off one node and then upgrade that host from 2012 to 2012R2. I can then migrate VM's onto that node (but not back off it again). Then I repeat for each node until I have all 7 on 2012 R2. Does anyone know if this information is correct or would I need to start from scratch?
Thanks in advance
Richard
