I install Rancher2.5.5(rke) and created cluster.
And I upgrade rancher to Rancher2.6.0 with helm upgrade command.
Rancher2.6.0 web page cluster management shows below.
State Name Version Provider
Active cluster-name v1.19.6 RKE
Pulldown menu Edit Config shows nothing.
I would like to upgrade cluster v1.20.x or later.
How can I upgrade cluster provided by RKE?
