2 xboxes one person - 2 houses - 2 accounts transfer to one. Complex.

So can he now sign in in original one and write down the names of his gamer contacts then go licence transfer from [mod removed-personal information] to [mod removed-personal information] - then sign out of the original then sign
in on the new one [mod removed-personal information]. then he will see all his purchases on this new account transferred from the old account and the recent xbox live 1 yr subscription.

No. Nothing can be transferred between accounts.

As far as the first part of your post, he can sign into his account on the console at your house and have access to everything on his account.

Sorry, but nothing can be transferred between accounts and account cannot be merged.

Issues again with connectivity. Just making it known that seems to be wide spread. I have 2 Xboxs in my house with 2 different accounts. Neither are connecting to the profile. One on wired and one wireless

Thanks for the reply. He has his own account but it seems to be tied to my account. When he is playing on his xbox one and i try to play my xbox series x it says only one at a time. I would like to be able to play him at Fortnite for instance but it wont
let me. I bought him a xbox pass but he seems to be connected to mine all the time. Im thinking of wiping the xbox one and setting up an adult account for it for him to use so i dont have this issue.

You just need to have him have an xbox account and then set up one of the xboxs as the Home xbox and your live account will always be signed in there so anyone that signs on can play your games on xbox live. Then you will manualy sign into the second xbox
so you can also play your games and use xbox live. If the game you are playing has season passes or expansions you may need to buy them for both accounts but base games always work.
