Howto migrate RKE downstream cluster from one seed cluster to another with another URL

1. Assume you have 2 Rancher instances with the same Rancher version and the same underlying Kubernetes Infrastructur
2. Install rancher-backup on both Rancher instances
3. Perform a backup on the source instance. Best way to use S3 storage for easy migration. For this create a Secret with the S3 credentials
4. Restore the backup on the destination instance. EXTRA WARNINGS:
   • This step will import all clusters, nodes, users, tokens.
   • Rancher settings will be overwritten from the source instance, incl. admin user, 3th party auth like Keycloak, UI layout

• If restore task isn't completed, it will retry in a loop. You may observe restart loops of Rancher PODs which is caused by the restore process. Look at the cattle-resource-system namespace in rancher-backup POD logs. In any case the restore should stopped or with kubectl delete restore deleted
