Note: You should have Nucleus already installed before trying this. If you haven't done so yet, download nucleus now.
No officially supported conversion scripts are currently available for Nucleus v3.2. We can provide some pointers to some "non-official" tools, however. (generally meaning that we didn't test them)
If you'ld like to write your own conversion script, there's a document available on the Nucleus SQL table structure that can get you started.
