Installing the Zerto Solution : Repairing the Current Installation
  
Repairing the Current Installation
If a new installation is the same version as the installed version, the Repair the Zerto 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 options, as described in section Upgrading To More Than One Version Higher, in the guide Upgrading the Zerto Virtual Replication Environment to save the settings.
If the vSphere Client console was open during the repair, close it and reopen it to ensure you use the upgraded Zerto User Interface.
