MQ Series co-existing with Enterprise Broker

Here is the current scenario at one of the sites where webMethods’ EAI is to be implemented. The disparate systems at the organisation are integrated with MQ Series. If we implement Enterprise Broker into this system, how will the architecture look like? How is the communication between MQ and wM going to be? In the “to-be” scenario do we have to reconfigure the adapters of MQ with wM or is it that we just build in the Business Logic into the messaging system of MQ Series using Business Integrator?

I would appreciate if anybody could give me insights into this issue.
