I bought a new Xbox One x to replace my old original Xbox but mcc was on my old one and I don’t know if it’s possible to get it back on my new one

It is possible to get it back for sure. If you own a disc, all you have to do is insert it and install it again. You’ll have to download an update as well.

If you have the game installed on an external hard drive, simply plug it in to your new Xbox.

If you own it digitally or play on Game Pass, simply navigate to the relevant menu - Ready to Install or the Game Pass section, both of which are under “My Games and Apps.”

Enjoy your X! MCC is easily one of the best looking games along with Forza Horizon 3/4 and FM7.

Edit: Came back to add another option I forgot to mention earlier. If you connect both Xboxes to the same network, you can transfer MCC using the aptly-named “network transfer” feature on your Xbox. Navigate to Settings and it should be under either “Network” or “Storage.”
