Upgrading the EKS Control Plane

Version 23.2 of the ArcSight Platform requires Kubernetes version 1.26.

Because Amazon EKS runs a highly-available control plane, you can upgrade only one minor version in one step. Therefore, if your current version is 1.24 and you wish to upgrade to 1.26, then you must first upgrade your cluster to 1.25 and then upgrade it from 1.25 to 1.26.

Note: Each EKS control plane upgrade can take 20-30 minutes to complete.
  1. In AWS, browse to the EKS console.
  2. Click Clusters.

  3. In the list of clusters, next to your cluster, click Update now.

  4. Select the next Kubernetes minor version, and then click Update.
  5. Repeat steps 3-4, as needed, to complete the upgrade to version 1.26.

Before proceeding, wait until the Status changes from Updating to Active.
