Ok I get this (thanks!)

But let's go back to my original situation. Original itinerary is on UA outbound and LH return all in B class. Ticketed in B on 016 ticket stock.

LH return upgrade has cleared (into LH "I" bucket) using Star Alliance Upgrades. No impact to UA reservation.

UA reservation on outbound flights are the following:
-Domestic hop to a hub (trying for instant B upgrade, but isn't available)
-Transatlantic flight from hub to EU. Waitlisted for biz class upgrade with GPU

In my scenario, none of my times, flight #'s, cities are changing.

My question is if the GPU upgrade clears (or the B instant upgrade) will that require the ticket to be "resynced"? And if the answer is yes, is this with or without a ticket reissue.

I think the answer is yes to needing to be resynced, but no to the ticket reissue since all original flight coupons are still valid.
