+    With OOO we configure a separate DB for placement for the undercloud and
+    overcloud since the beginning.
+    But the placement_database config options were reverted with
+    https://review.openstack.org/#/c/442762/1 , which means so far even if
+    the config option was set, it was not used. With rocky the options were
+    introduced again which is not a problem on a fresh installed env, but on
+    upgrades from queens to rocky.
+    We should use the same DB for both fresh deployments on and upgrades to
+    rocky before we switch to the new DB as part of the extraction of placement.
