4 Upgrading OCNWDAF

This section provides information on how to upgrade an existing OCNWDAF deployment. The section describes the preupgrade tasks, supported upgrade paths, and the upgrade procedure.

Note:

If the environment has cnDBTier 23.2.0 installation, follow the instruction below:

• If cnDBTier 23.2.0 release is installed, set the ndb_allow_copying_alter_table parameter to 'ON' in the cnDBTier custom values dbtier_23.2.0_custom_values_23.2.0.yaml file and perform cnDBTier upgrade before install, upgrade, or any fault recovery procedure is performed for OCNWDAF. Set the parameter to its default value, 'OFF' once the activity is completed and perform the cnDBTier upgrade to apply the parameter changes.
• To perform cnDBTier upgrade, see Oracle Communications Cloud Native Core, cnDBTier Installation, Upgrade, and Fault Recovery Guide.
