OME v2.2 Tiered-Deployment

I'd like to deploy a subordinate/site instance of OME v2.2 and have it interact with a managerial/main instance of OME v2.2 and create a centralized management network.  I have a primary instance in my data center, but I have servers in my test lab which function in an ad hoc enclave and only accessible using the lab's management server.  How do I tie the lab's OME server to my primary OME server?

Does that make sense?

Thanks,

Patrick
