Rollback Steps

To roll back to a previous version, follow the steps as mentioned:

Note:

• (Optional) A timeout interval of 15 minutes can be set while performing an upgrade as only one POD of the Data Director services is upgraded at a time.
• Ensure the status for the target version is not in failed or error state.

1. Run the following command to check the revision you must roll back to:

   $ helm history <release_name> -n <release_namespace>

   Where,

   <release_name> is the release name used by the Helm command.

   <release_namespace> is the OCNADD release name, for example, ocnadd.

   Example:

2. Run the command to rollback to the required revision:

   helm rollback <release_name> <REVISION_number> --namespace <release_namespace>
       --timeout=15m

   Where, <REVISION_number> is the release version to which Data Director needs to be rolled back is obtained in the previous step.

   Example:

   helm rollback ocnadd 1 --namespace ocnadd --timeout=15m

   If the rollback is not successful, perform the troubleshooting steps mentioned in Oracle Communications Network Analytics Data Director Troubleshooting Guide..
