Yes and no !
Upgrade inventory overall is becoming ever more difficult to find, but J-F is (for the most part...) easier than Y-J - which is what the OP is looking for.
Many J cabins are going out 100% full these days (varies by sector of course) and even when there looks to be space a couple of weeks out, there can be many op-ups to status pax booked in Y, hence the empty seats being filled at the last minute.
It's a jungle out there ......
