Transferred games from Xbox One to Xbox X will not play?

At least from what I was finding on the network, if you can transfer games from the hard drive from an xbox one to an xbox one x

After game transfer from an Xbox one my add ons show to be installed but do not work in gameplay. Any ideas?

I ment i transferred add ons from a Xbox 1 to a Xbox seires X

You will not lose your games saves when you upgrade to the Xbox One X from Xbox One as your game saves are stored on the Cloud.

You don't have to transfer game saves from the Xbox One to the Xbox One X.

They (game saves) will sync once your console (Xbox One X) is connect to the internet.

Hope this helps you, djdaniele95.

Hello,

Keep in mind that this would only apply to games that support Smart Delivery, which is a feature that the developers decide to enable. The full library is confirmed here:

GTA 5 is one example that doesn’t support Smart Delivery - meaning that you would unfortunately need to purchase the game again if upgrading to a Series X|S. Your game saves/progress (including your online character) can be transferred, though:

Hope this helps.

you need to sign into the same account that originally purchased them and connect to the Internet so that they can be validated to the new console

You should also set the new system as your home if you intend it as your primary
