You can't export from 2.x and import into 7.0 - you'll have to do a three (or maybe 4) step migration - 2.x to 3.x, upgrade from 3.x to 4.x and from 4.x to 7.x I believe - it'll be a long journey to be sure. 2.x hasn't been supported or tested in years - which is why I finally took the tools down - they were parking on a lot of space on the site.
I have archives around - if you ping me off line I can get you most of the tools you need. Frankly I'd probaby just get a CSV dump of your top level user data and import it into a Unity 7 system - doing the multiple import/export/upgrade hop seems ripe for disaster...
