Cross vCenter vMotion require below component, big catch is both the vcenter must be in Enhanced linked mode.
- 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.
- Both vCenter Server instances must be time-synchronized with each other for correct vCenter Single Sign-On token verification.
- For migration of compute resources only, both vCenter Server instances must be connected to the shared virtual machine storage.
