You upgrade VMware Integrated OpenStack to VMware Integrated OpenStack 3.0 or 3.1 by installing a Debian patch, deploying a separate VMware Integrated OpenStack 3.0 or 3.1 deployment, and migrating to the new, upgraded deployment from your existing VMware Integrated OpenStack deployment.

Before you begin

  • Verify that you have matching resources for every node except the memcache and RabbitMQ nodes. See the hardware requirements in the VMware Integrated OpenStack Installation and Configuration Guide.

  • Back up your current deployment. For details, see Back Up the VMware Integrated OpenStack Deployment.

  • To preserve your current VMware Integrated OpenStack configuration, export it as a configuration file from the VMware Integrated OpenStack manager.

About this task

The update process requires vSphere to accommodate the existing deployment and the upgraded deployment. You must make available additional resources, datastores, IP addresses, and so on, to complete the upgrade procedure. vSphere continues to hold both deployments until you determine that the upgrade process was successful and you do not need to roll back to your previous VMware Integrated OpenStack deployment.

Important:

Upgrade only preserves customizations configured in the custom.yml file. Any changes or customizations made directly to the OpenStack deployment, such as SWIFT, are not preserved. It is responsibility of the OpenStack administrator to track such changes and re-apply them after the upgrade.

Note:

If you are upgrading from VMware Integrated OpenStack 2.5.1, the only supported upgrade is to VMware Integrated OpenStack 3.1.
