vSphere Replication uses the replication technologies included in ESXi with the assistance of virtual appliances to replicate virtual machines between primary and secondary sites.

To use vSphere Replication, you must deploy one vSphere Replication appliance at each site. The vSphere Replication appliance is registered with the corresponding vCenter Server instance on each site. For example, on the primary site, the vSphere Replication appliance registers with the vCenter Server instance on the primary site.

The vSphere Replication appliance provides a virtual appliance management interface (VAMI). You can use this interface to reconfigure the vSphere Replication database, network settings, public-key certificates, and passwords for the appliances.


vSphere Replication is distributed as an OVF virtual appliance. You must deploy the appliance at both of the primary and secondary sites.


To use vSphere Replication between two sites managed by different vCenter Server instances, you must configure a connection between the two vSphere Replication appliances.


You uninstall vSphere Replication by unregistering the appliance from vCenter Server and removing it from your environment.


If the vSphere Replication appliance virtual machine does not exist because it was deleted, you cannot use the virtual appliance management interface (VAMI) to unregister vSphere Replication from vCenter Server. Instead, you can use the Managed Object Browser (MOB) to delete the vSphere Replication extension.
