Sorry for the confusion in the schedule. Below one is what I meant.
Phase-1: Now -> Ussuri-1 milestone (deadline R-22 )
** Project to dropping the py2 support along with all the py2 CI jobs.
Phase-2: milestone-1 -> milestone-2 ( deadline R-13 )
** This includes Oslo, QA tools (or any other testing tools), common lib (os-brick), Client library.
Phase-3: at milestone-2
** Final audit on Phase-1 and Phase-2 plan and make sure everything is done without breaking anything.
This is enough time to measure such a break or anything extra to do before Ussuri final release.
