Transfer data to new account?

I know I'm not getting the account back, but surely there must be a way to just transfer the data to my new Microsoft account right? The account itself is not what matters, it's the data (which includes the account I've had for a decade). Is it possible to get that data transferred to my new account?

So game save data wont be shared? Ex: call of duty dlc can be shared throughout the accounts on that console?

Hello,

Sorry, it's not possible to transfer any sort of content from one gamertag to another. Any sort of game data that one gamertag saves can only be used with that gamertag. All achievements earned on one gamertag cannot be transferred to another.

However, if you use this same console where your current gamertag exists, all other gamertags on this console should have access to all of the games and downloadable content on the same Xbox 360.

Game saves will not work on any other account except for the one that you played the games with. As far as DLC and games you've purchased on that account, those should be available to use on other accounts as long as they are on the same console as they
were purchased on.

It depends on whether or not they put the game on the new xbox and if they developers allow the data to transfer to the new consoles version but all data is connected to account.
