Have been doing this in production for years now with Cluster-API + Talos.

When I update the Kubernetes or Talos version new nodes will be created, and after the existing pods are rescheduled on new nodes the old nodes are deleted.

Works pretty well.

I think most of us learned this from an early age - computer systems often degrade as they keep running and need to be reset from time to time.

I remember when I had my first desktop PC at home (Windows 95) and it would need a fresh install of Windows every so often as things went off the rails.
