Guidelines to Upgrading Zerto Virtual Replication
■ 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.
■ The following table shows what version you can upgrade to, based on the current version running at the site.
Current Version: | Can Upgrade to: |
4.0, 4.0Ux | 4.5Ux |
4.5, 4.5Ux | 5.0Ux |
■ Zerto recommends upgrading to the
latest version of Zerto Virtual Replication that supports the environment you are using. Refer to the
Zerto Virtual Replication Interoperability Matrix for the list of environments supported by this version of Zerto Virtual Replication.
■ A Zerto Virtual Manager can be used with a different version on another site, as long as the other version is only one version higher or lower.
■ The following table shows what versions can be used on a peer site, based on the version on the current site.
Version N (This Version) | Version (N-1) | Version (N+1) |
4.0, 4.0Ux | 3.5, 3.5Ux | 4.5 |
4.5 | 4.0Ux | 5.0Ux |
5.0Ux | 4.5Ux | N/A |
■ 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 Zerto Virtual Replication, the VRAs that were installed in the previous version are not upgraded automatically.
Zerto recommends that you always upgrade the VRAs on your site to the latest version.
If a newer version of the installed VRAs exists, you can
continue to use the current VRAs with the new version of Zerto Virtual Replication,
or upgrade these VRAs from within the Zerto User Interface, as described in
Upgrading VRAs.
