are Ceph and CephCluster referencing the same content? (wondering if we can use the same variable then)

They are downstream, but we can't call a cluster a "Red Hat Ceph Storage" cluster upstream. I'm not sure if a cluster should be called "Ceph Storage" upstream, or just "Ceph."

= Migrating Red Hat Ceph Storage RBD
= Migrating Red Hat Ceph Storage RBD to external RHEL nodes

For hyperconverged infrastructure (HCI) or dedicated Storage nodes that are running version 6 or later, you must migrate the daemons that are included in the {rhos_prev_long} control plane into the existing external RHEL nodes. The external RHEL nodes typically include the Compute nodes for an HCI environment or dedicated storage nodes.
For hyperconverged infrastructure (HCI) or dedicated Storage nodes that are running {Ceph} version 6 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.

To migrate Red Hat Ceph Storage Rados Block Device (RBD), your environment must meet the following requirements:

* Red Hat Ceph Storage is running version 6 or later and is managed by cephadm/orchestrator.
* NFS (ganesha) is migrated from a {OpenStackPreviousInstaller}-based deployment to cephadm.For more information, see xref:creating-a-ceph-nfs-cluster_migrating-databases[Creating a NFS Ganesha cluster].
* Both the Red Hat Ceph Storage public and cluster networks are propagated, with {OpenStackPreviousInstaller}, to the target nodes.
* {Ceph} is running version 6 or later and is managed by cephadm/orchestrator.
* NFS (ganesha) is migrated from a {OpenStackPreviousInstaller}-based deployment to cephadm. For more information, see xref:creating-a-ceph-nfs-cluster_migrating-databases[Creating a NFS Ganesha cluster].
* Both the {Ceph} public and cluster networks are propagated, with {OpenStackPreviousInstaller}, to the target nodes.
* Ceph Monitors need to keep their IPs to avoid cold migration.

= Migrating {Ceph} RGW to external RHEL nodes

For hyperconverged infrastructure (HCI) or dedicated Storage nodes that are running {Ceph} version 6 or later, you must migrate the RGW daemons that are included in the {rhos_prev_long} Controller nodes into the existing external Red Hat Enterprise Linux (RHEL) nodes. The existing external RHEL nodes typically include the Compute nodes for an HCI environment or {Ceph} nodes.

To migrate Ceph Object Gateway (RGW), your environment must meet the following requirements:

* {Ceph} is running version 6 or later and is managed by cephadm/orchestrator.
* An undercloud is still available, and the nodes and networks are managed by {OpenStackPreviousInstaller}.
