Upgrade the software version, descriptor version, components, repository details, instantiation properties, and Network Function properties of your CNF and map them to the newer version in the Catalog.

If the existing Helm Chart requires a software upgrade, the system upgrades the software version of the CNF instance. If the existing CNF instance is not present in the new catalog, you can map the current CNF instance to a new Helm Chart. If you do not make a selection, then the existing CNF instance is removed from the Workload Cluster.

Note: If there is an issue during the CNF instance update or upgrade operations, you can resolve the issue based on the error message and trigger the update or upgrade operation again. For example, during the upgrade operation, if an image is missing in the Harbor repository and the operation fails due to this, you can upload the missing image and retry the upgrade operation.
Note: The selection of multiple node pools during CNF instantiation would also result in customization during CNF upgrade. It will continue to use the same batch size value that was defined during CNF instantiation.
