Hi I recently upgraded our non-prod rancher to 2.6.6 and when I try to upgrade the k8s from 1.19.4 to 1.23.6, I run into the following error and had to restore to my snapshot
The IngressClass "nginx" is invalid: spec.controller: Invalid value: "k8s.io/ingress-nginx": field is immutable
any idea what I am missing?

Did you try in steps (1.19.4 -> 1.19.x -> 1.20.x -> etc) or went straight from 1.19 to 1.23?
I was told at one of Rancher Rodeos to perform the k8s upgrade in steps and so far that has not failed me... (fingers crossed and knock on the wood 🙂)

I tried the straight upgrade to 1.23, this sounds good too. thanks @hundreds-evening-84071
