How to change the system number and system name for distributed systems?

If you want to connect WinCC OA systems using distributed systems, they need to have unique system numbers and names.

With the command line tool WCCOAtoolSyncTypes (can be found in WinCC OA installation folder/bin) it is possible to change the name and number of an existing system.

1) Stop the project

2) Make a backup of the database
If HDB archiving is used there is no need to make a backup of the VA_* directories as they are not modified when changing the system number and/or system name.

3) Open a command line window/terminal and switch to the bin folder of your used WinCC OA installation (e.g. C:\Siemens\Automation\WinCC_OA\3.15\bin).
Run the following command:

WCCOAtoolSyncTypes -proj <the project name> -system <new System number> <new System name> -log +stderr

4) Wait until the command is finished and check the log output if an error is written
