How to change System number and name of an existing project?

Because only Systems with different names and numbers can be connected via dist, each system in WinCC OA needs to have a unique System name and number.

If Systems with should be connected which have the same numbers or names, one of the Systems need to be renamed and the number needs to be changed:

1)    Stop the project if it is running

2)    Run the command line tool WCCOAtoolSyncTypes.exe from bin folder of the WinCC OA installation with the following options:
WCCOAtoolSyncTypes -system <new System number> <new System name> -proj <your project name>
e.g. C:\Siemens\Automation\WinCC_OA\3.11\bin\ WCCOAtoolSyncTypes –system 3 dist_3 –proj myDistSystem3
