My org running is running rancher 2.6.3 and RKE2 1.21.5+rke2r1, we are planning on doing the upgrade to rancher 2.6.5 and rke2 to latest, would love to know if there is a documentation on how to do it. I have experience doing on RKE so one of the important question is are the commands and process same?

RKE and RKE2 are very different, so the upgrade experience is also different. RKE2 has its own docs for how to upgrade a cluster: https://docs.rke2.io/upgrade. Make sure if you’re upgrading minor versions, to upgrade between minors one at a time (1.21 --> 1.22 --> 1.23 --> etc). Upgrading your Rancher install should follow the same procedure you’re used to: https://ranchermanager.docs.rancher.com/v2.6/getting-started/installation-and-upgrade/install-upgrade-on-a-kubernetes-cluster/upgrades

Thank you Max, I have few more questions. Might well post it little later
