Upgrade Release 1 components and modules that aren't managed by Helm.

All Oracle CNE Release 2 applications in the application catalog are managed by Helm. During the cluster upgrade, all installed applications managed by Helm are automatically added to the application catalog. This means they can be upgraded to the latest release using the CLI or UI, when required. Upgrading applications isn't part of the upgrade from Release 1 to Release 2, and can be done at any time after the formal upgrade in this document. For information on upgrading applications in Release 2, see Oracle Cloud Native Environment: Applications.

Some Release 1 applications need manual intervention to change them so they're managed by Helm, and then the application must be manually upgraded. If any of these modules or components are in the Release 1 cluster, follow the steps in this section to update them:

• Flannel

• Istio Module
