RDO website offers two scenario for <a href="https://www.rdoproject.org/install/upgrading-rdo/">upgrading</a> OpenStack Mitaka to OpenStack Newton. The first scenario involves taking down all of the OpenStack services at once and will not bring them back up until the upgrade process is completed. The second scenario upgrades each OpenStack service one by one to avoid downtime by performing rolling upgrades of the compute hosts, taking advantage of the fact that nova-compute from Mitaka can communicate with a Newton control plane.</p>
