To ensure a successful virtual machine replication, you must verify that your virtual infrastructure respects certain limits before you start the replication.

The following operational limits apply to vSphere Replication:

  • You can only deploy one vSphere Replication appliance on a vCenter Server instance. After you deploy another vSphere Replication appliance, during the initial configuration process in the VRMS Appliance Management Interface, vSphere Replication detects another appliance already deployed and registered as an extension to vCenter Server. You must confirm if you want to proceed with the new appliance.
  • Each newly deployed vSphere Replication appliance can manage a maximum of 3000 replications, of which up to a 1000 can be within the same vCenter Server instance. See for more information.
  • vSphere Replication 8.4 uses only an embedded database and requires additional configuration to enable the support of a maximum of 3000 replications. See
