2017! Typed too fast and didn't proofread before hitting POST.
You would get whatever the gate value of the ticket was on Feb. 11, 2017 applied toward your upgrade or AP purchase. In the case of a 7-day hopper, that gate value would have been $467.54 (tax incl.). From a post on the TPAS by Robo, you may actually get a few dollars more for that ticket but not the current gate value of a 7-day hopper. It's not guaranteed to happen so it's best to go into guest services with the expectation to get nothing more than $467.54 applied to your upgrade.
