I was wondering if there are any issues updating OpenSearch to 2.19.4?
I'm currently using DMA 10.5.3 with OpenSearch 2.11.0. There are some vulnerabilities detected by my organizations VA scans that relate to OpenSearch 2.11.0 and I would need to rectify this.
Thanks!
Hello Andrew, you can upgrade from OpenSearch 2.11 → 2.19 with a rolling upgrade so the cluster stays available. OpenSearch uses semantic versioning, so 2.x → 2.y is a supported minor upgrade path, with breaking changes only between major versions.

We recommend that you back up your cluster state and indexes using snapshots. Snapshots you take before an upgrade can be used as restore points if you need to roll back the cluster to its original version.
Yes sir,
Rolling upgrades, sometimes referred to as “node replacement upgrades,” can be performed on running clusters with virtually no downtime. Nodes are individually stopped and upgraded in place. Alternatively, nodes can be stopped and replaced, one at a time, by hosts running the new version. During this process you can continue to index and query data in your cluster.

Thanks, Ryan… Your input has been most helpful.
Hi Ryan.. Thanks for your input.
Quick question. When you say rolling upgrade, that means I upgrade one OpenSearch node at a time right?
