[rdo-list] RDO-release for OpenStack Mitaka

hi, We had a OpenStack Swift Cluster consisting of a keystone node, a Swift proxy node, and 6 Swift storage nodes. All of them run in CentOS 7 x86_64. Just a few days ago, we tried to upgrade from our current Juno release to Mitaka. We found out that to get MySQL database on keystone node to be migrated is a huge pain. At first, I migrated the database from Juno to Kilo, and then from Kilo to Liberty, and then finally tried to migrate from Liberty to Mitaka, but failed. The famous error message is "Can't DROP 'ixu_user_name_domain_id'; check that column/key exists") [SQL: u'ALTER TABLE user DROP INDEX ixu_user_name_domain_id']", which was reported by someone else as a bug https://bugs.launchpad.net/keystone/+bug/1572341. This bug was fixed on July 7, 2016 which is after the rdo release. I am wondering if it is possible to have a new rdo-release for Mitaka to include these bug fixes, otherwise, the existing production Keystone database couldn't be migrated without great pain. Thanks a lot for your attention, and your suggestions are highly appreciated regards
