title: Angular 4 navigation using ui-router
body: <p>I am upgrading to angular 4.  I am currently using ui-router with states for navigation.  I have a mix of angular 1.x and all new development is in angular 4.    I was hoping that i could map new routes to old using RouterModule.forRoot(appRoutes, {useHash: true, enableTracing: true})</p>
  
  <p>How can I navigate from a new angular 4 component to an old angular 1.x page?</p>
