Comment 10 for bug 1588131

The python-keystone package (2:9.2.0-0ubuntu1) cannot upgrade from a version prior to kilo because the migration scripts in keystone/common/sql/migrate_repo/versions are missing migration scripts prior to DB version 67 (kilo). The latest version in the 1:2014.1.3-0ubuntu2.1 package is DB version 44.

This seems to be a serious problem that will affect anyone upgrading their servers from Trusty to Xenial. Without a complete migration path, keystone will fail.

It is ridiculous to force the admins to go find all of the intermediate keystone versions and incrementally upgrade each one (Icehouse, Juno, Kilo) until they get to one that will work.
