2015 Jeep Cherokee TrailHawk infotainment upgrade

Trying to upgrade the info center from the stock 2015 to a 2019 unit so I get the CarPlay added. Is it just as simple as a straight swap? Both are from jeep cherokee’s. All I’ve seen is that you have to upgrade the usb ports and have to get a theft pin from the dealer for the theft system to work. Is that really it? Will everything else work as intended? Appreciate any advice, testimonials, or if anyone can link any videos they’ve used or know of.
