Considerations for upgrade when disaster recovery is configured
When disaster recovery is configured, both the primary and secondary sites are upgraded in parallel and you are required to start the upgrade from only one site.
Review the following guidelines before you upgrade:
Upgrade can be performed only when both the primary and secondary sites are up and nodes are in healthy state.
Download and upload the upgrade package to only one of the sites.
After the upgrade package is uploaded, before you start the upgrade, navigate to and click . This will sync the upgrade package to the secondary site and trigger pre-checks on both the sites automatically.
Upgrade can be triggered from any cluster and both clusters are upgraded simultaneously.
If the upgrade fails on any cluster for any reason, both the clusters are rolled back to the previous version.
