I actually have a follow up question for this. Will this plan still work if the host is using a dvSwitch? If we disconnect the host from vCenter, and then import it into our new vCenter, the VMs suffer downtime without a dvSwitch correct?
To resolve this, could we setup a standard switch with all of our port groups on the host and migrate the VMs from the dvSwitch to the Standard switch? Or would this not work because we would need to use the same NIC's.
