5 Rolling Back OCNADD

The upgrade for OCNADD is managed as a migration; therefore, a Helm-based rollback is not feasible for the current release. In the event of a failed migration, a rollback to the old deployment can be achieved by routing the traffic from source NFs back to the old deployment, provided that the Post-Migration Task has not yet been performed and the old deployment is still present. If the Post-Migration Task has been completed and the previous deployment is not available, rollback can be performed by executing fault recovery on the older release.
