ZVM0007

A new version ({version}) is available for upgrade, but the current site cannot upgrade to it. Possible causes include you have an old peer which the new version will not be able to communicate with or because you have a VRA running an older version which the new version will not be able to communicate with.

You can only upgrade Zerto Virtual Replication to one version higher with full protection maintained. One of the sites is already running a version one version higher but an upgrade to this is also available.

Possible Cause	Possible Resolution
The protected and recovery sites are running different versions of Zerto Virtual Replication. The peer site is running Zerto Virtual Replication one version higher than the local site and there is an upgrade available for this version, but the local site cannot upgrade to it directly, because it is two versions higher.	Upgrade Zerto Virtual Replication, first to the same version as the peer site and then upgrade both sites to the latest version.
The protected and recovery sites are running different versions of VRAs.	Upgrade any VRAs that can be upgraded.

You can upgrade from version n to the next version (n+1) of Zerto Virtual Replication including to any update within the current version. You cannot do an n+2 upgrade directly.

The order you upgrade the sites, protected or recovery, is not relevant as long as paired sites remain only one version apart.

Note: Upgrade releases are considered to be upgrades of the same version. Releases 4.5, 4.5U1, etc., are the same version.
