I am trying to do some work for a client and have encountered an unusual situation. The client originally had a vCenter appliance version 5.5 and three ESXi 5.5 hosts. The intent was to build a new ESXi 6.0 host on a new server they had purchased, deploy a new vCenter 6.0 appliance onto that host, then unregister the old ESXi 5.5 hosts from the old vCenter appliance and reregister them with the new. All that went as planned, however, I needed to move the vCenter 6.0 appliance off the new ESXi 6 host in order to enable EVC. I had to shut it down first because of CPU functionality differences so I powered it down, unregistered it from the new ESXi host and registered it with one of the ESXi 5.5 hosts. It powered on and came up without issue however it was not available on the network. The standard switch assigned to the NIC existed on both the new ESXi 6 host and the old ESXi 5 host. I finally moved it back to the new ESXi 6 host and it booted up and worked fine but I am unable to enable EVC while it runs there. Any ideas or suggestions would be appreciated.
