Upgrading VVR without disrupting replication
This section describes the upgrade procedure from an earlier version of VVR to the current version of VVR when replication is in progress, assuming that you do not need to upgrade all the hosts in the RDS simultaneously.
Note:
On a Cross replication VVR or CVR environment, full upgrade is not supported. Perform a rolling upgrade.
You may also need to set up replication between versions.
See Planning an upgrade from the previous VVR version.
When both the Primary and the Secondary have the previous version of VVR installed, the upgrade must be performed on the secondary site first and primary role shifted to the newly upgraded secondary. The old primary can then be upgraded.
Note:
If you have a cluster setup, you must upgrade all the nodes in the cluster at the same time.
