No.... I converted my Ultraboard 2000 to vB a year ago... You need the UltraBoard installation (not the backup, it doesn't work with the backup).
I can tell you that the importer here works great... Why Jelsoft doesn't adopt it as an official converter? Because it was not written by them... But it works, and you can confirm it by reading the pages on the UltraBoard importer thread...
Happy importing
