When replicating between Host A and Host B the target vm on Host B has a different IP and MAC address.
Currently vRanger 5.x creates the VM via API calls. Due to this method the MAC ID's are generated by the ESX host.
vRanger 5.3 will retain the MAC ID and VM UUID on the replica VM as long as both the source host and target Host are not managed by the same VC. You can not have duplicate mac addresses inside a single VC and host.
