Upgrading EKS

Prerequisites for the EKS Upgrade

This procedure will upgrade the existing control plane and worker nodes from their present Kubernetes version to a currently supported version of EKS (look for Hybrid Cloud Support in the Technical Requirements for ArcSight Platform 23.3). As the EKS version can be upgraded only one version number at a time, you must repeat this procedure for each incremental version until the cluster is at the required version.

During each stage of the upgrade, system replaces the worker nodes one at a time with the newer EKS version, so as to avoid data loss or excessive cluster downtime.

Next Step: Determine EKS AMIs
