Hi, sqlachemy-migrate already works on Python3. I sent a patch to add missing Python 3 classifiers, so the "caniusepython3" automated tool will stop reporting false alarm on this library. https://review.openstack.org/174738 Or is someone aware of issues with Python 3? Again, check the wiki page for up to date information: https://wiki.openstack.org/wiki/Python3#Dependencies > There seems to have been some work on that already: > https://github.com/stackforge/sqlalchemy-migrate/commit/a03b141a95 Yeah, Cyril made great work! I ported a lot of OpenStack libraries. Victor
