Upgrading Hyper-V Server 2012 R2 to 2016
Hello all, I have a couple of Hyper-V Server 2012R2 boxes (the free 'core' offering). Is anyone aware of procedures or documentation to perform an upgrade of these boxes to Hyper-V Server 2016??...
I prefer doing this: Create a cluster with your Hyper-V servers (failover role), then move (live migration) the VMs from the Host that will be upgraded and perform the upgrade.
Also you could perform a clean install as well.
Note: You mus have available RAM and CPU on the hosts to support the adicional VMs coming from the hosts you want to upgrade
Given that there is shared storage available to host the VM's (SAN CSV or Windows FileServer) that would seem like the way to go.
In our clusters we evict 1 node to perform a clean Windows 2016 install. After the upgrade and reconfiguration we re-join the node to the cluster. Rinse repeat for all cluster nodes.
I always prefer a clean install over a inplace upgrade for an OS.
