Xbox Series X [resolved] Great Western Express Route

I've just got the TSW 6 free edition and have managed to get my Tees Valley and Trans Pennine dlc routes from TSW 2020 to download onto the newer game. Is there a way to transfer my GWE route/ Class 43 loco over to TSW 6? It's content is on physical disk rather than downloaded dlc. Or do I need to keep my TSW 2020 version so I can continue to run this route?

 

I think you can contact DTG Support about this, raise a ticket with them.
