= 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.

== Prerequisites
Before you begin the migration, complete the tasks in your {rhos_prev_long} {rhos_prev_ver} environment. For more information, see the "{Ceph} prerequisites" in the "Adoption overview" chapter.
