Xbox live / Ultimate renewal 2 xbox one's

The ability to upgrade up to 3 years is always available if you're going from standard gold or game pass to Ultimate. You would have to check to see if the $1 promotion is available on your account. That promotion is only available for new subscribers.

So I'm assuming I would be considered as a new subscriber as I never purchased Ultimate before even though my brother did?

When renewing an Xbox Game Pass Ultimate subscription it converts the three months xbox live to 1 month xbox live. You can wait untill the subscription has fully ended to redeem three months of xbox live. I recommend buying many months or a year of xbox
live then buying one month of game pass ultimate it will change the whole subscription to xbox game pass ultimate. This can only go up to 36 months

Hi,

If you cancel Xbox Game Pass Ultimate you will no longer have all it has to offer. When you feel like cancelling you can go to microsoft.com and locate the subscription tab from there you can cancel your Game pass ultimate and Renew your Xbox Live Gold. Or you can go to subscriptions on the Xbox settings find your Xbox live Gold on there and Renew it that way.

If you want just game pass for them, one account must buy the game pass and be set as homebox. Then they can share game pass as same as live. But only on one console. College mentioned game pass ultimate. It is a good option. If you sign for ultimate,
they will have a month or two of ultimate, and all they Live converted to ultimate. For example. If you buy 2 months ultimate (there is an offer for 2 bucks now) and they have 5 months of Live, they will get 7 months of Game pass ultimate that includes game
pass. Live, and game pass for pc. If you buy with auto-renewal option, they will get one more month. If you don't like it, just wait for the period to pass, and then return to Live and game pass. Never cancel Ultimate, because you will lose remaining Live
time. There is no family pass.
