Similar to How to unlink epic games to then link to my actual account?, but not the same.
I have an Xbox live account, which is linked to my Epic account. My son doesn't like that when he plays Fortnite on the Xbox, his player name is my gamer tag. I want to create him his own Xbox account (free one), and then move the Epic account over to his gamer tag.
Is this possible? On the face of it, it seems so, but I will be the most hated man alive if he loses his Fortnite progress.
