Hi all I have Rancher v2.6.6 (upgraded from v2.6.3) installed and I am trying to upgrade the K8s cluster to the latest version. I am following the procedure at https://rancher.com/docs/rancher/v2.6/en/cluster-admin/upgrading-kubernetes/#tested-kubernetes-versions but it does not seem to have the correct steps.

In the upper left corner, click ☰ > Cluster Management.
On the Clusters page, go to the cluster you want to upgrade and click ⋮ > Edit Config.
From the Kubernetes Version drop-down, choose the version of Kubernetes that you want to use for the cluster.
Click Save.

When I Edit the config there is no dropdown menu.

The screenshot shows that you have an RKE template in use. RKE templates are designed to restrict Kubernetes configuration options from being edited. To upgrade Kubernetes there are two options: either change Kubernetes version in the RKE template and upgrade to the new version of the template, or mark the Kubernetes version as “allow user override” in the RKE template and upgrade the cluster to use the new version of the template.

Thanks for the info @tall-school-18125 🙂
