We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
1- only multiplayer data from COD:Ghosts and BF4 will transfer over, that is it (there may be a couple other games that transfer MP data but those are the two I know for sure). That is done through their servers. Single player saves from the 360 are not
accessible. you'll need to start new campaigns in each game.
2- only through typed messages. No cross gen party chat if that's what you're asking
Any movies and music WILL carry over to the Xbox One, which is something everyone else seems to have neglected to mention for some reason. However, you can't "transfer" it per se'. Rather, you have to go into Xbox Video & Xbox Music & either stream your
movies & music or re-download them from there. ;)
