I have a Hyper-V Server 2008R2 (free 'core' version) cluster that I would like to upgrade to Hyper-V Server 2012R2 (same 'core' version). I foundthis document that seems to outline the process, however I have the following questions...
Any reason this process won't work on the "core" version of Hyper-V. i.e. "Microsoft Hyper-V Server 2008R2". I currently have a 2-node 2008R2 HA cluster with "core" servers and am looking to migrate that cluster to the "core" version of 2012R2.
Is there no way to do this "in place", meaning without a dedicated target server? It seems like the process assumes you just have extra servers sitting around that can act as targets. I suppose I could shuffle VMs off one cluster node, evict that node from my current cluster, rebuild it with 2012R2 core, add it to a new cluster as the only node and carry on with the process outlined here? Once all VMs are on the new "cluster" of one 2012R2 node, I would destroy the original cluster, rebuild those machines with 2012R2 and add them as nodes to the new cluster?
Any reason the "Failover Cluster Manager" tool, version 6.1, I've been using to manage my 2008R2 environment won't work to do the migration? Or are there new 2012 tools I need to have installed on my workstation. Remember, since this is the "core" version I can't manage anything from the server.
Thanks,
Todd
