We should also say that if you upgrade both segments, but do it by picking the segments separately with separate prices (which sometimes can total to less than the cost to upgrade all flights in that direction), it *probably* will be treated as two sequential seat purchases and not lead to a reissue of the ticket, but I don't know whether there have been any reports here that address that situation.
