We're missing the code to run online data migrations of Nova, Cinder, and Ironic, after the services got containerized. This pops up as a problem during consecutive upgrades, e.g. when upgrading 11->12->13, the Ironic DB sync will refuse to run 12->13 schema change because the online migrations have not been run on OSP 12 yet.
Containers cinder_api_online_migrations, nova_online_migrations were successfully launched and executed during ffwd process. Package: openstack-tripleo-heat-templates-8.0.7-4.el7ost.noarch
