You should not have to rewrite much if any of your application, but you may need to repackage some of your code. The idea is to encapsulate the functionality in service components, then they are deployed using the pipelines framework. Its really pretty easy to do, the reference framework and examples show you what is required -- and its intended to be very lightweight and flexible.
