Moving a CD=player from one truck to another

[Cowboy7]

I am selling my 2013 Ram 3500 Longhorn Dually Longhorn and want to remove the CD player and put it in the 2015 Ram 2500 Laramie. Provided the Laramie is pre-wire to accept the cd-player, I assume I will need to take the 2015 truck to the dealer to re-flash. Would I need to take the 2013 truck to re-flash as well once the cd-player has been renewed? Thanks
