AFAIK you still have to update from major version to major version. With your example, this means: kilo -> liberty -> mitaka -> newton For the sake of completeness, "Ocata" is the latest stable release (Feb. 2017) and "Pike" will be the next release (Aug. 2017): https://releases.openstack.org/ The main reasons for this incremental update (IIUC): * database schema updates (and sometimes data migration) * deprecation/renaming of config options For the config options I'd like to point you to the (little known) tables of "New, updated, and deprecated config options": * Nova - Kilo: https://docs.openstack.org/kilo/config-reference/content/nova-conf-changes-kilo.html * Nova - Liberty: https://docs.openstack.org/liberty/config-reference/content/nova-conf-changes-liberty.html * Nova - Mitaka: (note the change in the URLs 'style') https://docs.openstack.org/mitaka/config-reference/tables/conf-changes/nova.html * Nova - Newton: https://docs.openstack.org/newton/config-reference/tables/conf-changes/nova.html * Nova - Ocata: https://docs.openstack.org/ocata/config-reference/tables/conf-changes/nova.html * and so forth for the other projects ... -- Regards, Markus Zoeller (markus_z) _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
