This is what I get when I try to migrate the vCenter appliance:
The target host does not support the virtual machine's current hardware requirements.
Use a cluster with Enhanced vMotion Compatibility (EVC) enabled to create a uniform set of CPU features across the cluster, or use per-VM EVC for a consistent set of CPU features for a virtual machine and allow the virtual machine to be moved to a host capable of supporting that set of CPU features. See KB article 1003212 for cluster EVC information.
CPUID faulting is not supported.

hostname
The vMotion interface is not configured (or is misconfigured) on the "Source" host 'hostname'.
hostname
A general system error occurred:
The IP address family of source vMotion nic (IPv6) does not match the destination (IPv4). If you proceed with the operation, there is a high likelihood of operation failure.
