How to Transfer Xbox 360 games to Xbox One?

Hiya, thanks for clicking.

So I have a couple of digital games on my Xbox 360 that I would like to transfer to my Xbox One. I understand you can use your Xbox Live account to do so, but what if I don't have it?

Let's use Black Ops 2 as an example. About a year or two ago, my sister's boyfriend downloaded the code for BO2 to my 360 for me using his account. Problem is, he is now her ex, so there is no way I can use his account to put it on my Xbox One. Is there a way I can transfer BO2 to my One without the account? Or can I license transfer the game to my own account without accessing his? Thank you so much for the help, you guys are awesome. :)

If I'm understanding you, you won't be able to access any games on any other account than your own. The only exception is if you gameshare with your girls ex. That would allow you to play his games, and he yours.

@sealionact: Alright, so you're saying there's no possible way to make the game transferred to my account? Not even license transfer?
