I have a 2008 R2 Core Cluster using Datacenter hosting a variety of VMs and now we would like to move to Enterprise as the platform for the cluster. It would be best if we didn't have to stop the system to do this. I was thinking of adding an Enterprise box and adding it to the cluster and then replicating to it and then killing the original Datacenter boxes and then creating another Enterprise box and cluster to it. Is there a way to cluster between Datacenter and Enterprise? If not that can we live migrate from a Datacenter cluster to an Enterprise cluster?
