Yes, save data can be carried over to the full version of the game. Please note that the demo is available on PlayStation 5, Xbox Series X|S, Steam, and the Epic Games Store.
As long as you have the save data for the demo stored on your device (and are logged in to the corresponding first-party account), a message will show upon launching the full version with instructions on how to transfer your progress.
Please note that this message will not show if you have any save data from the full version. If you want to transfer the save data from the demo again, please delete the save data from the full version first.
