You upgrade VMware Integrated OpenStack to VMware Integrated OpenStack 2.5 by installing a Debian patch, deploying a separate VMware Integrated OpenStack 2.5 deployment, and migrating to the new, upgraded deployment from your existingVMware Integrated OpenStack deployment. This 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.

Double the datastore resources dedicated to your current VMware Integrated OpenStack deployment.

Verify that you have twice the required number of IP addresses available. For details, see Add IP Addresses to the Network Configuration.

You must 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.

1

The upgrade procedure requires a temporary number of IP addresses in addition to your existing IP address configuration. vSphere provides a tool that enables you to add this required IP range.

2

The VMware Integrated OpenStack 2.5 upgrade is a Debian patch. When you install the upgrade patch, you upgrade the VMware Integrated OpenStack Manager vApp.

3

After you obtain and install the upgrade patch, you install it as a separate deployment, migrate your data, and switch from the VMware Integrated OpenStack 2.0.x deployment.

4

You can revert to VMware Integrated OpenStack to a previous version by restoring your previous deployment.

5

After you complete the upgrade process to the VMware Integrated OpenStack 2.5 deployment, you can delete the older VMware Integrated OpenStack deployment. By deleting the old deployment, you recover the CPU, datastores, and IP addresses resources that it required.

6

VMware Integrated OpenStack 2.5 supports Load-Balancing-as-a-Service (LBaaS) v2.0.VMware Integrated OpenStack enables LBaaS v1.0 automatically, but as part of the upgrade process you have the option of migrating to and enabling LBaaS v2.0.
