title: Angular 6 Migration -.angular-cli.json to angular.json
body: <p>I've upgraded my project to Angular 6, and everything went fine except the conversion of <code>.angular-cli.json</code> file. From the guide I followed, it was said that this will convert it automatically.</p>
  <blockquote>
  <p>npm install -g @angular/cli</p>
  <p>npm install @angular/cli</p>
  <p>ng update @angular/cli</p>
  </blockquote>
  <p>However, it was not the case as I still have the old <code>.angular-cli.json</code></p>
  <p>Is there a way to do it automatically / manually?</p>
