+## Rocky Server Notes
+- `rocky_server` is an empty child of both `platform_rocky` and `server`; it must stay empty until a
+  real migration target is ready.
+- The active `prometheus` host remains in `ubuntu_server`. Never place the same inventory host in both
+  `ubuntu_server` and `rocky_server`; use a distinct name while testing a parallel replacement.
+- The target must already provide `server_username` with local sudo access before the profile runs.
+- The Rocky profile installs Docker CE, uses firewalld, preserves SELinux enforcement, and renders the
+  same server Compose stack. It does not transfer data, start containers, update DNS, or cut over traffic.
+- Atlas-only OpenZFS, NFS, Samba, Cockpit, and native Syncthing packages stay selected through Atlas
+  host variables and must not leak into `rocky_server`.
+
 ## Atlas NAS Notes
 - `atlas` is a remote Rocky Linux 9 NAS. Keep its connection, LAN, pool and mountpoint values in
   `host_vars/atlas.yml`. Bootstrap it once with `-e atlas_connection_username=<existing-admin>`;
