A: Before you begin the upgrade process, make sure that you take any necessary precautions such as: * Back up your applications, database schema, other application data, and domains. * If required, obtain latest third party plug-ins or components that are compatible with required non-Oracle components. For example, Apache Web Server libraries. CGED: The rolling upgrade process includes stopping the Administration Server, installing the upgrade, restarting the Administration Server, and then doing the same for each Managed Server in the cluster (machine).
