[Plugin: Joomla To WordPress Migrator] Does this work with older versions?

I’ve got a heap of content on old Joomla sites that I want to convert to fresh wp installs. I’m using Joomla 1.0.12

I see you list that its been tested on 1.5 – do you have any comments about whether it would work with 1.0.12

thanks

Paul
