Transition a Windows Server 8 to Windows 2012 Release Candidate Hyper-V Cluster

For those of you interested in moving their lab from Windows Server 8 beta to Windows Server 2012 Release Candidate I can refer you to my 3 part blog series on Upgrading Hyper-V Cluster Nodes to Windows Server 2012 (Beta).

  1. Part 1 Upgrading Hyper-V Cluster Nodes to Windows Server 2012 (Beta) – Part 1
  2. Part 2 Upgrading Hyper-V Cluster Nodes to Windows Server 2012 (Beta) – Part 2
  3. Part 3 Upgrading Hyper-V Cluster Nodes to Windows 8 (Beta) – Part 3

So the entire process is very similar but for the fact that to go from Windows Server 8 Beta you have to do a clean install on every node you evict during the process. An upgrade is not supported and not possible. I even tried the old trick of editing the cversion.ini file in the sources folder to lower the supported minimum version for an upgrade, but no joy.imageimage

You probably remember this trick to enable an upgrade form the beta/RC  to RTM with Windows Server 2008 R2/Windows 7  But that doesn’t work and even if it did it would not be supported.

But just follow the 3 part series and do an fresh install instead of an upgrade of the cluster nodes and you’ll be just fine.
