There are no database schema changes in the Train release, but there are
checks to confirm that online migrations from Stein have been run. Running
:doc:`/cli/placement-status` *after upgrading code but prior to restarting the
placement service* will notify you of any missing steps and the process to fix
it. Once this is done, :doc:`/cli/placement-manage` should be run to sync the
database::
$ placement-status upgrade check
