To enable migration across vCenter Server instances, your environment must meet these requirements:
The source and destination vCenter Server instances and ESXi hosts must be running version 6.0 or later.
Both vCenter Server instances must be in Enhanced Linked Mode and must be in the same vCenter Single Sign-On domain so that the source vCenter Server can authenticate to the destination vCenter Server.
