migrating to a new doc type

we are using developer 6.5 and I need to update the output docType for the service.
I using the xmlNodeToDocument Flow and mapping the node to the docType.
We have a newer version of the docType and I would like to know if there is a way to use this new docType without having to remap all the links.

I cannot modify the existing docType because it is in use by other services.


I figured out how to trick the developer into getting this to work.
I created a map step earlier in the service and in that map step added a doc type and gave it the same name as the one I wanted to replace but used the new doc type instead. With the inherit characteristics of WM the new doctype replaced the old one because it was not previously defined.
