You can reconfigure or break an existing site pair.
If you have problems with an existing site pair, you can attempt to reconfigure the site pair with the Reconfigure Site Pair action. When you provide the required credentials, the reconfiguration operation attempts to repair the existing site pair.
With the Break Site Pair action, you can break the pairing between a vSphere Replication instance on the protected site and the virtual data center on the vCloud Director account of your organization.
Note:
You cannot use the Reconfigure Site Pair action to add a missing pairing or a pairing that was manually broken with Break Site Pair. If your site pair is missing a pairing, you must use New Site Pair to configure it.
