title: Change App ID of Apple Watch App
body: <p>I have recently transferred some of my apps from one account to another. When I did this the App IDs also transferred. However, the App IDs did not transfer for the WatchKit Apps or WatchKit Extensions. </p>
  
  <p>I have tried to upload and after the upload has completed and appears in iTunes Connect Prerelease I receive an email about <code>CFBundleIdentifier Collision</code>. </p>
  
  <p>I then tried to change the App ID for the Apple Watch app and see this error when uploading:</p>
  
  <pre><code>Attempting to change bundle identifier from com.domain.myapp.watchkitapp to com.domain.myapp.watchkitapp2 is disallowed for bundle MyApp.app/PlugIns/MyApp WatchKit Extension.appex/MyApp WatchKit App.app.
  </code></pre>
  
  <p>Do you have any suggestions? Thanks</p>
