+===========

+Moves BlueFS data from source volume(s) to the target one, source volumes
+(except the main, i.e. data or block one) are removed on success.
+
+LVM volumes are permitted for Target only, both already attached or new one.
+
+In the latter case it is attached to the OSD replacing one of the source
+devices.
+
+Following replacement rules apply (in the order of precedence, stop
+on the first match):
+
+    - if source list has DB volume - target device replaces it.
+    - if source list has WAL volume - target device replaces it.
+    - if source list has slow volume only - operation is not permitted,
+      requires explicit allocation via new-db/new-wal command.
+
+Moves BlueFS data from main device to LV already attached as DB::
+
+    ceph-volume lvm migrate --osd-id 1 --osd-fsid <uuid> --from data --target vgname/db
