= Migrating Red Hat Ceph Storage RBD to external RHEL nodes

:context: migrating-ceph-rbd

[role="_abstract"]
For Hyperconverged Infrastructure (HCI) or dedicated Storage nodes that are
running {Ceph} {CephVernum} or later, you must migrate the daemons that are
included in the {rhos_prev_long} control plane into the existing external Red
Hat Enterprise Linux (RHEL) nodes. The external RHEL nodes typically include
the Compute nodes for an HCI environment or dedicated storage nodes.

Before you begin the migration, complete the tasks in your {rhos_prev_long} {rhos_prev_ver} environment. For more information, see xref:red-hat-ceph-storage-prerequisites_configuring-network[{Ceph} prerequisites].
