How do I un-connect my Xbox One account from my Xbox 360?

If you still have access to the console, you'd need to delete your profile from it.

If not, you can go here and click "Require Profile Download". That will make it so that in order to use your account on any 360, the account has to be downloaded again first. As long
as you haven't given out your account information, no one will be able to sign into your account to use it.

ok, say i buy a used xbox 360. i can get a free/paid avatar prop with it and transfer it to my xbox one, right? how would i do this? i assume the xbox 360 would have to be connected to the internet which means i'd have to disconnect my xbox one from the
internet and connect the 360 to the 'net. after i get the prop onto the 360 how do i get it onto the xbox one? also, during transfer do the 360 and xbox one both need to be connected to the 'net or just one or the other? not sure if i'd be able to have 2 consoles
connected to the internet at the same time.

K I got 360 but get xbox one n had to get new account how do I get all my dlcs from 360 to go to xbox one n have my new account go to 360 to??

I think this is more a question of “how do I make a guest account on 360 backwards compatible games” since I have this issue with all my 360 games on xbox one so is there a way to add guest accounts on 360 games when playing on xbox one? because from my experience it’s not as easy as adding a guest account on xbox one

How do i put my Xbox 360 account on Xbox one.
