Do I need to pay for Xbox live if I have Xbox one? Ddo I need to change billing information? Or I can just buy 360, sign into my Microsoft account and I'm good? (I have xb1)
So I just have to change billing information to 360 and continue paying and it covers both consoles?
Gold is the same on both consoles. There's not a Xbox One gold and 360 gold. As long as you're using the same account you'll just have gold on both consoles.
So, I would have to stop paying for Xbox one gold and start paying for 360 gold? That's what I have to do?
You can use the same account on both the 360 and the One. You would only need to change billing information if you need to update the info. Yes, you still need gold to play online on the One.
