Description RHOS Integration 2013-12-12 13:52:23 UTC
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/convert-to-alembic.

Description:

SQLAlchemy-migrate is fine for straight-line migrations, but does not really support branching, needed for clean backports of some but not all migrations to a stable branch.  Alembic has better branching support and will meet our needs better.  We should switch migration frameworks, and convert our existing migration scripts to Alembic syntax.
