It is said that playing old games on Xbox series X is as easy as inserting a mobile hard disk. As long as the Xbox one game is preinstalled on this drive, you can play it on Xbox series X immediately. However, it should be noted that although Xbox series X supports moving the game between the internal and external hard disks, the new game can only run if it is saved on the built-in SSD, such as halo: infinite, one of the first lineups.
