title: Combine Web API 2 and Service Stack in one app
body: <p>I am developing an application with Angular 1.5 and Web API 2, but I would like to switch to ServiceStack. The app is running already in production.</p>
  
  <p>The idea is to have v1 with Web API (.../api/v1/...), implement v2 with ServiceStack and after some time drop v1.</p>
  
  <p>I wonder if it is possible to combine Web API 2 and ServiceStack in one web host? If no, what is the best way to proceed with a smooth transition without spending time on rewriting the whole code with ServiceStack in one step?</p>
