Yes, I need find out the best approach to upgrade our Vcenter Appliance & Updating
Server & also the ESXi 5.1 to version 5.5. Also just as a precautionary measure if i
clone my vcenter appliance and something happens during the upgrade can I just
revert back to my clone and start over without causing problems. Also should I upgrade
the esxi hosts from withing vcenter or from the cd at each host.
