I've been googling around for this, and find all kinds of opinions. Is it better to pull the local datastore (and the HBA with the SAN datastore), do a fresh install of v5, re-do the minimal config, re-add the datastores, etc... Or do an in-place upgrade instead? I've had people tell me the latter is safe, but I keep thinking if something goes wrong, there goes my info (although I do have the VMs backed up - it would be a PITA to recover them.) What do you all do in these cases?
