Upgrade a Single Controller

You can use the Enterprise Console to onboard and upgrade a single node Controller instance. The Custom Install Discover & Upgrade option in the GUI allows you to create a platform and discover a Controller.

Alternatively, if you have already created a platform, you must add credentials and hosts to the platform before you can perform discovery. Then, discover the Controller on the page. Discovering a Controller means that the Enterprise Console learns about your existing Controller deployment, such as profile, tenancy mode, existing domain configuration, and database configuration. This information is used to perform an upgrade.
