Installing Over an Existing Version

If you install the database server over an existing installation, the installation program prompts you to choose one of the following options:

• Install new files without changing configuration.

  The installation program uses the existing database server configuration and installs the new database server over the existing database server.

• Install new files and reconfigure, overwriting existing data.

  The installation program removes all existing database server configuration information, installs the new database server over the existing database server, and displays new database server configuration screens.

• Copy all files and perform upgrade.

  The installation program uses the existing database server configuration and installs the new database server over the existing database server.

• Install in a different directory.

  Use this prompt to install multiple versions of the database server on your computer. The installation program installs the new database server into the directory that you specify and prompts you to configure it. The program does not delete the existing database server or change its configuration. In this case, each installation has its own program group on the Programs menu.
