Correct. Not without doing the work yourself to make it possible, and realizing that it's untested/unsupported and likely will bring out gremlins. In order to make db migrations less painful, i.e. faster, Nova moved to a system where only schema changes occur in the sqlalchemy-migrate migrations and all data is migrated by another nova-manage command which can be run while the system is in use. But the side effect of this is that the data migration needs to take place for each release, and there are checks in place to ensure this happens. Unless you have an empty database "nova-manage db sync" won't even complete successfully for kilo->mitaka since there's a check in place to ensure the liberty data migration took place. > > Sam > > > > On 25 Jun 2016, at 4:16 AM, Jonathan Proulx <j...@csail.mit.edu> wrote: > > > > Hi All, > > > > I about to start testing for our Kilo->Mitaka migration. > > > > I seem to recall many (well a few at least) people who were looking to > > do a direct Kilo to Mitaka upgrade (skipping Liberty). > > > > Blue Box apparently just did and I read Stefano's blog[1] about it, > > and while it gives me hope my plan is possible it's not realy a > > technical piece. > > > > I'm on my 7th version of OpenStack for this cloud now so not my first > > redeo as they say, but other than read Liberty and Mitaka release > > notes carefully and test like crazy wonder if anyone has seen specific > > issues or has specific advice for skiping a step here? > > > > Thanks, > > -Jon > > > > -- > > [1] > > https://www.dreamhost.com/blog/2016/06/21/dreamcompute-goes-m-for-mitaka-without-unleashing-the-dragons/ > > > > _______________________________________________ > > OpenStack-operators mailing list > > OpenStack-operators@lists.openstack.org > > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators > > > _______________________________________________ > OpenStack-operators mailing list > OpenStack-operators@lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
