Hello everyone, I have an RKE cluster with k8s 1.21.13 and I want to upgrade it to 1.22. I have Rancher 2.6.6 running on this RKE cluster. I checked the 2.6.6 compatibility matrix and it says that only 1.22.9 is supported for RKE clusters. The issue is that when I run "rke config --list-version --all", only v1.22.10-rancher1-1 is listed and not 1.22.9. Will the 1.22.10 version work too? Or can I somehow install the 1.22.9 version using the RKE binary?

It should be possible to expand the number of Kubernetes upgrade options without upgrading Rancher https://rancher.com/docs/rancher/v2.6/en/admin-settings/k8s-metadata/

@tall-school-18125 Thanks for your reply! That's good to know, I was not aware of this. Although I think I will likely take the safer route and use the k8s version that is officially supported as per Rancher docs. Once 2.6.7 is released I will patch k8s accordingly.

I wouldn't expect issues, but we only support the latest patch version for each minor version because that is what was used for testing and that would also contain important security fixes

Alright, I see. I really appreciate you taking the time to reply. Thanks and have a nice day!
