Change Primary Domain Google Apps Free edition From March 15th , 2016 Google has updated , can not change the primary domain. But I’ve figured out a loophole in Google Apps system to Swap Primary Domain or adding Secondary Domain for Google Apps legacy account. Please add domain and verify your domain name before ordering and send me your administrator account .. I'll help you change Primary Domain on your account. Note: You are only allowed to use two domains in a free account (one for the primary domain and one for secondary domain).
