Hey,
We currently have a 2 node 2008 R2 cluster and we've got new hardware to replace these. The new hardware is running 2012 R2.
What is the best process to migrate things over? I actually thought I could add the 2012 R2 servers to the existing cluster and just live migrate VMs to them, then remove the old servers from the cluster.
No downtime then. Nothing else is new (storage, networking etc.).
But on the Add Node wizard it says nodes must be running the same hardware, software, drivers etc. etc. Can 2012 R2 servers be added as nodes to a 2008 R2 cluster?
Thanks
