Hi diztorted, thanks for the reply.
At the moment our cluster has 5 hosts, one of which is the new 3.5 host (Quad Core).
So what you are saying is, remove the host from that cluster and create a new cluster with that host in, enable EVC, and then VMotion the remaining VM's off the other four hosts on this new host, and this will work?
I had no idea this was possible. Is there anyone else who has done this, or any documentation etc. I can look at ?
Is there any risks with losing data with creating a new cluster and moving the guests over?
Thanks
