You can revert to the previous VMware Integrated OpenStack deployment if the upgrade failed or if you do not want to use the new version.
Important: The old deployment is required for reversion. If you have already deleted the old deployment, you cannot revert to the previous version.
Procedure
What to do next
If you chose to stop services instead of deleting the new deployment, you can manually remove its virtual machines in the vSphere Client. If you deleted the new deployment, its virtual machines are removed automatically.
