Upgrading Cloudera AI Registry in 1.5.5 SP2 CHF1 and lower releases

Upgrade Cloudera AI Registry by provisioning a new parallel instance, synchronizing model data, and removing the legacy environment.

In Cloudera AI 1.5.5 SP2 CHF1 and lower releases, the upgrade process creates a separate registry instance.

  1. In the Cloudera console, click the Cloudera AI tile.

    The Cloudera AI Workbenches page is displayed.

  2. Click AI Registries under ADMINISTRATION in the left navigation menu.

    The AI Registries page is displayed.

  3. Select a registry to upgrade.
  4. Copy the CRN from the AI Registry details.
  5. In the Cloudera CLI, enter the cdp ml upgrade-model-registry --crn <crn> command.

    In the AI Registries UI, the Status of the AI registry changes to Backup Initiated. The process starts provisioning a new registry (Status: Creating) and then performs a backup operation to restore the state.

  6. When the status of the new registry displays Ready, select Synchronize from the Actions drop-down menu.
    Check the content of the new registry to verify that all models transferred successfully.
    • Open a workbench and confirm that all the models are available.
    • Review the Event Logs tab on the Cloudera AI Registry Details page to see if any errors occurred during the upgrade. The event logs can also be used in real time to confirm that the process is running.
  7. After verifying the content of the new registry, select Delete from the Actions drop-down menu for the previous registry (check the Created at timestamp).

If you upgrade a Cloudera AI Registry, perform a synchronization, and then perform a rollback. Any models added during synchronization will not be displayed in the previous registry. The rollback process does not transfer data back to the previous version.
