Hello, after upgrading to 2.7.5 recently, it was realized that one of the clusters (all VMware VM's) was at an unsupported version prior to upgrade (1.22). The cluster, and all connection to it, has effectively ceased to work or connect. I saw one article out there about potentially manually upgrading the nodes to get to a supported version that Rancher will work with again. The error is:"Cluster agent is not connected" My question: what is the fix/upgrade path for a cluster that is unsupported when Rancher is upgraded? Note - I am unable to query the cluster at all with the kubeconfig (just hangs). I can't figure out any other way to talk to the cluster to look at the status of the pods in case there is a trick/tip there I am unaware of. Thanks!
