Right, Nova (and probably other projects, too) only supports N to N+1 upgrades. If you need to go to N+2, you'll need to go through N+1 to get there. FWIW, improving upgrades is very high on the priority list across all of OpenStack. We have sessions all over the place to talk about it. It's getting a lot better. -- Russell Bryant _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
