I couldn't find the answer I was looking for, so here goes.
I would like to change my gamertag to something else, the changing process is the easy step to do. What I would like to know is how will it affect websites like xbox live rewards, bungie net, xbox.com, EA account and many more that uses your gamertag.
Will they automatically change to my new gamertag, do I have to do it manually or do I need to make a new account?
Thanks for reading
