see KB https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2106952 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. The cross vCenter Server and long distance vMotion features require an Enterprise Plus license. For more information, see Compare vSphere Editions. When using the vSphere Web Client, 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. When using the vSphere APIs/SDK, both vCenter Server instances may exist in separate vSphere Single Sign-On domains. Additional parameters are required when performing a non-federated cross vCenter Server vMotion. For more information, see the VirtualMachineRelocateSpec section in the vSphere Management SDK Guide. Requirements for Migration Between vCenter Server Instances You can use migration across vCenter Server instances if your system meets certain requirements. ■ Network Compatibility Checks During vMotion Between vCenter Server Instances Migration of VMs between vCenter Server instances moves VMs to new networks. The migration process performs checks to verify that the source and destination networks are similar. ■ MAC Address Management During Migration Between vCenter Server Systems When you move a virtual machine between vCenter Server instances, the environment specifically handles MAC address migration to avoid address duplication and loss of data in the network. Note During the migration of a virtual machine to another vCenter Server system, the performance data that has been collected about the virtual machine is lost. are thoose two environment in one DC or it's in different DC? if different consider also Long Distance vMotion KB Long Distance vMotion requirements in VMware vSphere 6.0 (2106949) | VMware KB
