Upgrade RT 2.0.15 to RT 3.2.1

I’ve been running RT for couple of years now, and I would like to port
the data I already have on my old host to a RT 3.2.1 I installed on a
new host running Fedora.

I tried looking for some info on upgrade/ database migration in the RTFM
and wiki but all I found was notes about a tool called

which I couldn’t find anywhere.

Anyone have pointers about this.

Upgrade path required:

RT 2.0.15 , mysql-3.23.41-1 on Red Hat Linux 7.2 -> RT 3.2.1,
mysql-4.0.21 on Fedora r1
