Deploy service from Centrasite to broker w/o registry

I am migrating from Centrasite 7.2 to ActiveSOA 8.2. Our architecture is such that we will need to deploy our production service from the repository to an ESB . I understand that I coulde deploy a Proxy definition of the service to the ESB and either store that in a configuration file or service directory for runtime. I am not sure if this is possible looking for ideas.
