Upgrading To More Than One Version Higher
Before upgrading to a new version, make sure that all VPGs are in Protecting state and not in a sync state, such as Delta Sync, or an error state, such as Needs Configuration.
If you need to upgrade more than one version higher, do one of the following:
1. Upgrade versions stepwise, one version at a time, as described above in Upgrading Multiple Sites Running Different Versions, until you reach the required version.
- or -
2. Use the Zerto Diagnostics utility’s export option to export the existing VPG definitions, then uninstall the old version of Zerto Virtual Replication. Install the new version, then use the Zerto Diagnostics utility’s import option to re-create the VPGs. Use the following procedure.

8. Install the new Zerto Virtual Replication version, as described in the Zerto Virtual Replication Installation Guide.
9. Install the VRAs on the hosts in the site and pair the sites, as described in Zerto Virtual Replication Installation Guide.
