Zerto Virtual Replication and Microsoft Hyper‑V Features : Live Migration
  
Live Migration
If you use live migration to migrate a virtual machine, which is part of a VPG, from one host to another host, before moving the virtual machine make sure that:
The host to which you are moving the virtual machine has a Virtual Replication Appliance (VRA) installed on it, as described in the Zerto Virtual Replication Installation Guide.
The virtual machine is not a test virtual machine running on the recovery site during the performance of a failover test, as described in “Testing Recovery”, on page 185.
Do not migrate a Virtual Replication Appliance (VRA) from one host to another. Also, do not migrate a virtual machine on the recovery site that is being updated from the VRA journal until promotion of data to the virtual machine completes.
