Before you begin:

  1. Make sure the earlier version of the software is not running when you run the Configuration Upgrade Utility. Doing so will avoid potential port conflicts and allow you to accept default port assignments.

  2. If you are upgrading a Linux or UNIX system, make sure that no startup scripts are running.

  3. Verify that you have administrator privileges. If not, you will be prompted for credentials.

  4. Uninstall the services, such as the MSS Server and MSS SecurityProxy.
