Vb 3.8 to phpbb Custom Fields

[P0ny]

Wondering if anyone can help please. I've searched but can't seem to find the answer. I originally posted in the correct topic but doesn't look like anyone's visited in there some time and I need a solution soon. So, apologies for cross posting it here too but thought I may get a better response.

I want to convert my existing VB3.0.8 forum to phpbb and would like to carry over some custom profile fields that are simple text - first name, last name, some dates and so on.

Could anyone tell me of a way to modify the convertor and/ or make the necessary alterations to the database?

Thanks in advance.
