Preupgrade Tasks

Before starting the procedure to upgrade OCNADD, perform the following tasks:

Note:

  • While performing an upgrade, you must align the ocnadd/values.yaml file of the target release as per the ocnadd/values.yaml file of the source release or the older release.
  • Do not enable any new feature during the upgrade.
  • The parent or sub-charts values.yaml parameter must not be changed while performing the upgrade, unless it is explicitly specified in this document.

For information about enabling any new feature through Helm parameters, see Oracle Communications Network Analytics Data Director User Guide.

  1. Fetch the images and charts of the target release as described in Installing OCNADD.
  2. Keep a backup of the current ocnadd/values.yaml file of the source release as a backup while upgrading to target release.
  3. Update the following helm chart files of the target release with the parameter values of the source release files:
    • ocnadd/values.yaml
    • ocnadd/ocdd-db-resource.sql
    • ocnadd/templates/ocnadd-secret-hook.yaml
    • Update the pvcClaimSize parameter of all the Kafka brokers ocnadd/charts/ocnaddkafka/values.yaml.
