Before upgrading, ensure that your management and API access networks include sufficient IP addresses to support the existing and new deployments concurrently.
The IP addresses that you configure in this procedure are permanent. After you migrate to the new deployment, these IP addresses will be used instead of the IP addresses assigned to your existing deployment. You will need to update any DNS entries or other references to VMware Integrated OpenStack IP addresses once the upgrade is finished.
Important: Do not include the IP address of the
OpenStack Management Server in the management network IP range. If you have already allocated additional IP addresses for upgrades, assign the first available IP address to the
OpenStack Management Server and remove it from the management network IP range.
