Upgrading Zerto Virtual Replication : Guidelines to Upgrading Zerto Virtual Replication : Upgrading Environments Using Zerto Cloud Manager
  
Upgrading Environments Using Zerto Cloud Manager
For environments using the Zerto Cloud Manager you must:
Upgrade the Zerto Cloud Manager to be consistent with the latest version of Zerto Virtual Replication run by the CSP.
Upgrade the version of Zerto Virtual Replication run by the CSP after the Zerto Cloud Manager, so that they are never more than one version separated from each other.
In other words, the Zerto Cloud Manager version should be: N or N+1, where N is the ZVM version.
For details about upgrading Zerto Cloud Manager, see Zerto Cloud Manager Installation Guide.
Note: Zerto no longer supports vCenter Server vApps. Any VPG protecting a vAPP should be recreated using the virtual machines in the vApp. When upgrading to 5.0Ux, if there is a VPG protecting a vCenter Server vApp, the following error appears, and the upgrade is stopped: Zerto no longer supports protection of vCenter Server vApps. Create a new VPG with the virtual machines from the vApp added separately to the VPG.
