Moving a Host Between Clusters
To move a host between clusters, you must first decommission the host, remove roles from the host, and complete other tasks.
- Decommission the host.
- Remove all roles from the host (except for the Cloudera Manager management roles).
- Remove the host from the cluster but leave it available to Cloudera Manager.
- Add the host to the new cluster.
- Add roles to the host (optionally using one of the host templates associated with the new cluster).
