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.
To upgrade more than one version higher, you need to upgrade versions stepwise. Meaning, upgrade one version at a time, as described above in Upgrading Multiple Sites Running Different Versions, until you reach the required version.
