You back up your existing data to the new deployment and then migrate to the new deployment. This procedure starts the new deployment and stops the old deployment.

Prerequisites

  • Install VMware Integrated OpenStack 5.1. See Install the New Version.

  • On the new OpenStack Management Server, apply the latest patch to VMware Integrated OpenStack 5.1. For instructions, see the release notes for the latest patch.

    Note: If you have upgraded your deployment from version 3.1 or earlier, you must patch to version 5.1.0.1 or later before proceeding.
  • If you have enabled Ceilometer, disable it before upgrading.
    1. In the vSphere Client, select Menu > VMware Integrated OpenStack.
    2. Click OpenStack Deployments and open the Manage tab.
    3. On the Settings tab, click Ceilometer and click Disable.
  • Mount a remote NFS server to the new OpenStack Management Server. This server is used to back up data from the old deployment and transfer that data to the new deployment.

Procedure

  1. Log in to the new OpenStack Management Server and prepare a directory to store the backup. 
    sudo viocli upgrade prepare old-mgmt-server-ip /nfs-server-folder
  2. Log in to the old OpenStack Management Server and back up its data to the prepared directory. 
    sudo viocli backup mgmt_server new-mgmt-server-ip:/nfs-server-folder
  3. Log in to the new OpenStack Management Server again and reconfigure the new installation using the data backed up from the old installation. 
    sudo viocli upgrade mgmt_server backup-directory new-mgmt-server-ip:/nfs-server-folder

    The backup directory name is in the format vio_ms_timestamp.

  4. Log out of the vSphere Client and log back in.
    This refreshes the interface so that the new deployment is displayed.
  5. In the vSphere Client, select Menu > VMware Integrated OpenStack.
  6. Click OpenStack Deployments and open the Summary tab.
  7. Verify that the Version Information table shows the version of the new VMware Integrated OpenStack installation.
  8. Under Connected Server, click Connect Server....
  9. Select the new OpenStack Management Server and click OK.
  10. Open the Manage tab and click the Upgrades tab.
  11. In the table displayed, right-click the current deployment and select Upgrade.
    1. Enter a name for the new deployment.
      This name must be different from the name of the current deployment.
    2. If you are upgrading from a compact deployment, select a deployment type for your new deployment in the Deployment type drop-down menu.
      During the upgrade process, you can change a compact deployment to an HA deployment if desired.
    3. Click Next, review the upgrade configuration, and click Finish
    The status of the current deployment is Running, and the status of the new deployment is Provisioning.
  12. After the status of the new deployment changes to Prepared, right-click the name of the old deployment and select Migrate Data.
    Important: This action will stop OpenStack services. Services will be down until the upgrade finishes.
    When the migration process finishes, the status of the new deployment changes to Migrated.
  13. Right-click the name of the old deployment and select Switch to New Deployment.
    When the migration process finishes, the status of the new deployment changes to Running, and the status of the previous deployment changes to Stopped.

Results

OpenStack services are now provided by the new deployment.

Important: Do not perform any operation that adds or removes nodes until you have completed the process described in Delete the Old VMware Integrated OpenStack Deployment. These operations include the following:
  • Enabling Ceilometer
  • Adding or removing compute clusters
  • Adding or removing Swift clusters or nodes

What to do next

  • Upgrade your license key in My VMware. See KB 2006974.
  • Update any DNS entries to use the IP addresses of the new VMware Integrated OpenStack deployment.
  • For NSX-T Data Center deployments, update the metadata proxy configuration in NSX Manager to use the IP address of the new OpenStack Management Server.
  • If you integrated your deployment with vRealize Automation, perform the integration procedure again. See Integrate VMware Integrated OpenStack with vRealize Automation.
  • If you integrated your deployment with VMware Identity Manager, remove the existing configuration from custom.yml and reconfigure integration using the new procedure. See Configure VMware Identity Manager Federation.

If the upgrade is unsuccessful or you do not want to use the new version, you can revert to your previous VMware Integrated OpenStack deployment. See Revert to a Previous VMware Integrated OpenStack Deployment.

If the upgrade is successful, you can delete the old VMware Integrated OpenStack deployment. See Delete the Old VMware Integrated OpenStack Deployment.
