I have Rancher 2.6.1 running on EKS version 1.20. (Both Server and Production Cluster) I want to upgrade both of these. All nodes in the server cluster are running Amazon Linux, and the downstream cluster nodes are using Ubuntu. For the rancher server cluster I launched it with EKS (eksctl) and did not use a custom AMI. The production cluster I created a launch template with a custom AMI and created the cluster with Rancher console. I am looking for advice on the best way to upgrade. I think I can do the following: • Upgrade Rancher to 2.6.8 (can I go directly or do need to do it in steps?) • Upgrade server cluster to 1.21 and then to 1.22 Using AWS Console Upgrade Downstream Cluster would be a multi stage process. • I have to create a new AMI using the correct base AMI + my customizations.. • Upgrade the cluster using the AWS console to 1.21 • Re-launch all nodes with the matching AMI • Upgrade the Cluster using the AWS console to 1.22 • Re-launch all nodes using the matching AMI Do I have it right?

you can jump directly from 2.6.1 => 2.6.8 Upgrade the k8s versions 1 at a time At no point are you outside of the support matrix Looks like a pretty solid upgrade strategy to me
