Make sure that the ticket is reissued. You should get a new emailed receipt with a new ticket number. It's not enough just to see OK for the segment in your PNR. If the upgrade is confirmed, get the upgrade into domestic FC for your domestic connecting flight and again make sure that the ticket, not just the PNR, shows as FC.
