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.
Description
You can only upgrade Zerto 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. The peer site is running Zerto 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, 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.
Before upgrading, review the following documents for compatibility:
■ Zerto recommends upgrading to the latest version of Zerto that supports the environment you are using. See the Zerto Interoperability Matrix for the list of environments supported by this version of Zerto.
■ The order you upgrade the sites, protected or recovery, is not relevant as long as paired sites remain only one version apart, that is, only one version higher or lower.
■ When upgrading from versions prior to Zerto 6.0U2, changing the Journal Size Hard Limit requires restarting the VRAs.
■ During an upgrade from v6.0x to v6.5, all back up and repositories configurations are deleted.
Note: Upgrade releases are considered to be upgrades of the same version. Releases 6.0, 6.0U1, etc., are the same version.
■ The following table shows what version you can upgrade to, based on the current version running at the site:
Current Version:
Can Upgrade to:
5.5, 5.5Ux
6.0Ux
6.0, 6.0Ux
6.5Ux
6.5, 6.5Ux
7.0Ux
7.0, 7.0Ux
7.5
■ You do not need to move workloads during an upgrade.
■ When upgrading a protected vSphere or Hyper-V environment, after the upgrade, a bitmap sync is performed for VPGs on the protected VRA.
■ In a Hyper-V environment, SCVMM 2016 is supported on Zerto installations from version 6.0x.
■ Zerto Cloud Appliance is supported for Azure and AWS (ZCA) on:
