Was the cluster launched by rancher, or did you import it?
If rancher created it, you can upgrade from the cluster management page. If you imported it, you would need to trigger the upgrade yourself in AWS
I created it with rancher. However, I am using a custom launch template and customer AMI. So I don’t think the nodes would come up and join the cluster. They would be running the wrong version of kubernetes.
You can also upgrade the K8S version via AWS EKS Console. Rancher UI will reflect the upgrade. I dont see that it can be done via Rancher UI on all versions.
If you're using templates, you can create a new template and specify your K8S version then go to your cluster and migrate to the new template. This will then prompt an upgrade for all your nodes.
