This guide is intended for existing Oracle Fusion Middleware users who are upgrading their Oracle Fusion Middleware products to a more recent version or to the latest version. To follow the instructions provided in this document, the reader should be comfortable running system administration operations, such as creating users and groups, adding users to groups, and installing operating system patches on the computer where the products are going to be installed. Users on UNIX systems who are upgrading their Oracle Fusion Middleware software may need root access to run some scripts.
