Hi I have 3 master nodes (

control-plane,etcd,master

) and I am trying to update them. I do not use upgrade plan as I need additional operations, but the flow is the same. I do replace k3s and run kill to the process. it seems that it works on first node but after that 2 others are becoming

NotReady

, i do not see any or may missed the logic regarding the order on doing it in

k3s-upgrade

component. Moreover are there any limitation of k3s version compatabilities? Meaning if I have one of the nodes with version

v1.23.8+k3s1

and 2 others are still

v1.21.4+k3s1

- can it be a limitation? Thanks in advance 🙏 rancher employee

You can't skip minors like that. If you're upgrading from 1.21, you should upgrade all the nodes to 1.22 first, then 1.23, then 1.24, and so on. https://kubernetes.io/releases/version-skew-policy/
