Hi all, I have a Rancher v2.7.3 installed and many K3s clusters imported, some v1.21.5+k3s2 and some v1.25.6+k3s1.
It is not clear to me how to enable from RancherUI the automatic upgrade of k3s, since in the docs (Automated Upgrades | K3s) it is specified to not install the system-upgrade-controller on each K3s cluster if they are imported into Rancher.
Can you please help me to understand how to proceed? Thanks
Or if the correct way to upgrade a k3s cluster is manually from the Cluster Management -> Edit CLuster section, is it possible to upgrade more clusters at the same time?
