Mickeymax,
That is not upgrade but migrating from one tool to another. If I understand your question correctly, you are actually moving from MQ series to webMethods and looking for some API/code if that creates the wM mapping services by reading MQ code. There is no API or options available to do so.
Practically, a tool provider wouldn’t create any such thing. Do you see something in MQ wherein it can convert webMethods flow code to MQ code?
