Is it even worth it to attempt an upgrade from version 1.5?  As it appears each release is an incremental upgrade and requires an update script to be ran.  

I built a small "rinki dink" Access application to maintain the 1.5 database,  even connecting with Quickbooks via qodbc.  Am I just as far ahead to build some transfer queries?

There isn't a lot of manual content but we did modifiy the contact page a bit.

TIA
