Can well configured Plan(s) upgrade a plain k8s cluster on Ubuntu ?

[davidandreoletti]

Here is my env:

• Ubuntu 24.04 k8s cluster with several worker & 1 controller nodes
• Plain k8s v1.31 nodes.
  • Important: The cluster is not Rancher created/managed (k3s, rke, etc). It was created following the k8s's official doc.

I would like to upgrade (a) the ubuntu k8s packages (kubeadm, kubectl, etc) and (b) the k8s cluster version using 2 Plans:

• "Upgrade Ubuntu k8s packages" plan: It seems tweaking bionic.yaml plan would do.
• "Upgrade k8s cluster version" plan: If supported, what would a suitable Plan look like ?
