You upgrade to VMware Integrated OpenStack 6.0 by creating a new deployment and migrating to it.

You can upgrade from VMware Integrated OpenStack 5.1 to VMware Integrated OpenStack 6.0. If you are running an older version, first upgrade to 5.1 and then upgrade to 6.0.

In the upgrade procedure, you create a VMware Integrated OpenStack 6.0 deployment and migrate your existing deployment to it. This procedure requires that you have sufficient hardware and IP address resources to support two deployments temporarily.

You can revert to the pre-upgrade version if the upgrade is not successful or if you no longer want to use version 6.0. To revert an upgrade, see Revert to a Previous VMware Integrated OpenStack Deployment.

Note the following differences between a new VMware Integrated OpenStack 6.0 deployment and a deployment that has been upgraded from a previous version:

  • The OpenStack region name of a new VMware Integrated OpenStack 6.0 deployment is RegionOne. The OpenStack region name of an upgraded deployment is nova.
  • The names of Nova compute nodes in a new VMware Integrated OpenStack 6.0 deployment are in the following format: compute-vcenter-id-cluster-moid. The names of Nova compute nodes in an upgraded deployment are in the following format: nova-compute-number. After the deployment is upgraded, new Nova compute nodes use the new naming format, including nodes that are deleted and recreated.
  • A new VMware Integrated OpenStack 6.0 deployment includes the service and default domains only. The service domain contains accounts used by OpenStack services, and the Default domain contains accounts used by OpenStack users, including the admin account. An upgraded deployment also contains the local domain for backward compatibility.
