So I have a complicated situation but will simplify it down to ask the question!
Imagine 1 Xbox and 2 live accounts. Account 1 buys some arcade games and DLC that account 2 can also use because it's the first console on which the purchase was downloaded.
Want to replace Xbox but still have both accounts able to play the games and use the DLC. If I just get the new one and re-download from purchase history then account 2 will no longer be able to use them!
So what do I have to do??
