Move My EA Acct to my Son’s Acct

We bought Star Wars Battlefront 2 years ago for my son who was under 13 at the time I believe. He was never able to play unless he had an EA account but was unable to create one unless he was 16 or 18 (I don’t remember the exact age at the time).

So we had to create an EA account under my email. And we linked it to my Xbox profile. So for years, he was using my EA account under my Xbox GamerTag and building up all of that progress and skins.

Well… he is 19 now and going off to college. He has since created his own EA account for his own Xbox GamerTag but doesn’t use it to play BattleFront 2 because all of his progression and skins is under mine. So I can’t play the games I want to play, when I want to play because he is logged in as me. He still plays Battlefront 2 but under my Xbox Live profile. Which is really irritating because then I can’t play.  Is there anyway to move my EA account along with any associated progression and skins over to his EA account which is tied to his Xbox GamerTag?  We aren’t moving from one platform to another… it is still Xbox.

Thank you
