Installing Zerto Virtual Replication : Repairing the Current Installation
  
Repairing the Current Installation
If a new installation is the same version as the installed version, the Repair the Zerto Virtual Replication Installation dialog is displayed.
When repairing the version, all pairing, VRAs and VPGs defined for the site are removed. Use the Zerto Diagnostics utility options Export and Import to save the settings, as described in the section Upgrading To More Than One Version Higher, in the guide Upgrading the Zerto Virtual Replication Environment.
If the vSphere Client console was open during the repair, close it and reopen it to ensure you use the upgraded Zerto User Interface
