How to Upgrade to the Latest Major Version Release of OmniCenter from a Previous Version

When upgrading OmniCenter from one major version to another (for example, from OmniCenter 11 to 12), it is not possible to skip major versions. This is to protect the integrity of the data already on the system. It is, however, extremely important to make sure that whatever major version you are upgrading from is updated to the latest build of that code before upgrading to the next major version release.

The following procedure will ensure a smooth upgrade to a new major version release of OmniCenter from a previous major version. (Updates and upgrades can only be performed by an OmniCenter superadmin.)

  1. Begin by navigating to the OmniCenter Update page. From the main menu select Administration → System → Updates.
  2. Now, make sure that your OmniCenter is updated to the latest released code for your current major version (in this example 11).
  3. Once there are no more updates available, you are ready to upgrade to the next major version release of OmniCenter (in this example 12).
  4. Click the Update Now button to initiate the major version upgrade. (Yes, the button says “update”, but you are performing an upgrade.) Be sure to address any messages from OmniCenter regarding the proposed upgrade before proceeding (such as incompatible plugins, settings, etc.).

    Polling and monitoring will be temporarily disabled during the upgrade process. Please ensure that you have scheduled a maintenance window that covers all service monitoring (for at least 1 hour) before upgrading.

  5. Before the upgrade begins, you will be prompted to confirm the process. Make sure you have scheduled appropriate maintenance windows and are ready to begin the upgrade. Be sure to type CONFIRM into the dialog in all caps and click OK to allow OmniCenter to begin the upgrade process.
  6. OmniCenter will spend at least the next hour (depending on the size of your network) upgrading. Once this process begins, it cannot be stopped.
  7. When the upgrade is complete, you will see a completion message.
  8. You can then validate that the upgrade was successful by either navigating back to the OmniCenter Update page or navigating to the Help & Support page by clicking on the question mark (?) icon in the quick access icon menu at the top right of OmniCenter. The version number is displayed below the Netreo logo.
  9. Your upgrade to a new major version release is now complete. If you are upgrading through multiple major version releases, please repeat this process until there are no more updates for the major version you would like to use.
  10. Once you have finished upgrading to the major release version that you wish to use, you may stop any maintenance windows that you have scheduled for this upgrade event and begin using your new version of OmniCenter normally.
