How to Change Primary Domain in Google Apps

Now Google allows Google Apps users to change their Primary Domain as announced by Google Apps blog on 5th October 2015. However, the change can only be done through Google Apps Customer API interface instead on GUI in the Admin Panel.

Bear in mind that, you can only change Primary Domain from Secondary Domain. Domain Alias is not allowed. So, FREE Standard Version (called Legacy or Grandfather version) is out of luck, unless they already add the Secondary Domain in their account prior to 14th November 2014. This date is the day when Google disabled the function to add Secondary Domain in FREE Standard Version. Now, FREE Standard Version users may only add Domain Alias.
