Before you upgrade, run the preupgrade utility. You must have system administrator privileges to perform an upgrade.
The executable files that run the preupgrade and upgrade utilities are SyConfig (a graphical user interface (GUI) application that you start with syconfig.exe), and SyBatch (a command line utility you start with sybatch.exe).
Each new server version contains features that introduce parameters, commands, reserved words, and so on. preupgrade prepares the old server by making sure all necessary directories and settings are correct for the upgrade. When running preupgrade, manually stop and start the server. You need not start the server before running the syconfig.exe upgrade utility; the utility starts the server when needed.
