Import multiple 2.0.11 instances into one 3.0.6 instance

Hi,
at the moment we have 3 instances of rt 2.0.11.
The users, queues and tickets shall be migrated
into one new instance of rt 3.0.6.
I’m using the rt2-to-rt3 module from Jan 24.2003
to export the data.
Is there a simple way to add a specified value to
the user_ids, queue_ids and ticket_ids so that
they all can live in one database?
I’m using SuSE Linux, Apache with mod_perl
and mysql.
