If you are installing Oracle Database software, then Oracle recommends that you use a preconfigured database option, or select the Advanced option on the Select Configuration page, and configure a custom starter database.

If you have an existing Oracle installation, then write down the version numbers, patches, and other configuration information, and review upgrade procedures for your existing installation. Review Oracle Database Upgrade Guide before proceeding with the installation.
