You upgrade to VMware Integrated OpenStack 5.0 by creating a new deployment and migrating to it.

You can upgrade from VMware Integrated OpenStack 4.0 or 4.1 to VMware Integrated OpenStack 5.0. If you are running a version older than 4.0, first upgrade to 4.1 and then upgrade to 5.0.

In the upgrade procedure, you create a VMware Integrated OpenStack 5.0 deployment and migrate your 4.x deployment to it. This 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 5.0. To revert an upgrade, see Revert to a Previous VMware Integrated OpenStack Deployment.
