I currently have a 2008 R2 cluster setup for both file sharing and printing. The two nodes in the cluster got screwed up due to a xenserver upgrade I did a while back. They are working now but some things still don't seem right so I want to create two new nodes and somehow transfer the services over to them. The new nodes will be Server 2012. I have read that all nodes in the cluster have to be on the same os but is there any way around this? I really don't want to change the name of the cluster considering that all file sharing and printers are associated to the current name. Will the following work to switch over to the new servers?
Setup 2 new nodes with Server 2012 and management and heartbeat nics
Add these nodes to the domain
Add the failover clustering role to the nodes
On the SAN setup the new nodes as hosts for the luns that are part of the cluster
Shut off all services on the cluster
Add the 2012 nodes to the cluster
Remove the 2008 R2 nodes from the cluster
Restart the services
Thanks.
