wso2 esb + api management

Question

I need to integrate WSO2 API MANAGER with an external ESO2 ESB, but don't know which configuration should I set up.

I know API MANAGER has a greg, should I mount ESB'registry to it? Also API MANAGER has an ESB, can I just share configuration of the external ESB with the API MANAGER's ESB?

Please Help!!

EDIT: the goal is to achieve a clustered environment with API MANAGER, but looks like the typical deployment configuration with a central registry (http://wso2.org/project/esb/java/4.0.3/docs/deployment_guide.html) does not work with API MANAGER, why?

EDIT2: the official page clearly says: "Horizontally scalable with easy deployment into cluster using proven routing infrastructure." i.e. "API manager can be integrated with others API managers" but is not really easy: while enabling cluster is matter of change a value in the axis2.xml the deployment synchronization does not work, or at least for me it doesn't. Any suggestion?

The ESB components which are used in API manager used to manage SLA and acts as a gateway. DO NOT ADD external ESB configurations in API manager. This is the documentation for API manager.It has clear guideline on how to add, what are the components etc..
