Hi, I'm running an rancher docker single instance installation. I got 3 clusters (dev,test,prod) (currently running k8s version v1.11.1) and want to upgrade a cluster to kubernets version 1.20.x. To do this I need to update rancher to the latest version. Is there a minimum required kubernetes version to use before upgrading to Rancher 2.5.8? I'm a bit afraid of below kubernetes version list. Am I required to run a minimum k8s v1.17.17 before upgrading to Rancher 2.5.8? https://rancher.com/support-maintenance-terms/all-supported-versions/rancher-v2.5.8/
