I believe that whenever I've looked at trading in a phone online with apple, it asks the question is the screen un-cracked? You might want to go thru the online motions to be sure. If so, maybe you can just pay the incident charge and then trade it in.So my wife is going to upgrade her iPhone XS to an 11 Pro tomorrow, she is on the annual upgrade program. But, she just managed to crack her XS screen. It is on the screen support Apple Care+.
The question is, does she need to first repair her her XS via the Apple Care+ program before doing the upgrade to the 11 Pro?
This is the info on Apple Care + She owes $29 for the cracked screen - want to make sure she doesn’t get charged more than that. https://www.apple.com/shop/iphone/iphone-upgrade-program
