The only update I have seen is to vBulletin 4
https://vborg.vbsupport.ru/showthread.php?t=232044
and even then, the functionality seems to be spotty at best.
For vBulletin 5 you will need to hire a developer and basically re-write the entire modification.
It might prove easier to migrate to Xenforo and use the Feed Back System addon.

which has an importer for iTrader built in. Also, the developer seems to be active so probably be able to provide additional assistance unlike anything vBulletin can currently attest to.
