Authentication error when deploying site's content
My guess would be that on this step: 


  For Endpoint URL, enter
  'http://your-destination-site.example.com/services/rest'. Click
  'Finish'. Note that it appears that any path other than
  '/services/rest' on either origin or destination generates a Request
  response error: -1002 missing schema.


Your entering the incorrect url. Make sure you are using clean url's. If not, make sure to include the "?q=" part for the path.
