Given an existing application with a hub-and-spoke design; the spokes being integration points with networked apps i.e. TCP/IP socket apps & webservices, how would you start refactoring such code when you are modifying:
1) the hub - i.e. the main application
2) one or more of the spokes - i.e. additional networked services to integrate or a modification of an existing protocol.
Thanks

What would be the driving force for refactoring the existing system?

I would start by writing integration tests. It is especially important not to change the API the legacy apps are expecting on a networked application.
After that, it depends on why you want to refactor.
