Axel,
reading the following: http://openstack.markmail.org/search/?q=migrate_flavor_data+order%3Adate-backward https://review.openstack.org/#/c/196911/ https://review.openstack.org/#/c/198060/
I believe, you should first get the controller to latest stable/kilo, run "nova db migrate_flavor_data" and THEN upgrade the code to Liberty.
