Can I move an existing Kubernetes cluster to Hosted Rancher?
Existing Kubernetes clusters can be imported into Hosted Rancher. However, you cannot currently move a cluster that is already managed by Rancher to Hosted Rancher. We are currently looking to enhance our management capabilities to allow users to move clusters between Rancher Clusters. See GitHub issue 16471. As a workaround, you can redeploy workloads running in an existing cluster over to a new Hosted Rancher managed cluster.
