Avaya Official tech bulletins state
to upgrade to 9.1 you can upgrade from 8.0GA or newer
to get to 8.0 you have to upgrade from 4.x/5.x/6.x/7.0
to get to 4.x (meaning 4.0 / 4.1 or 4.2) from 3.2 you can upgrade to 4.2
this means you can upgrade
3.2 - 4.2 - 8.0 - 9.1
or do what the other guys suggested, backup all
reinstall 9.1
upload the .mdb and put all the .wav files back (that is what I would do too)
