I currently use SMF for my forums on one of my sites. ..How can I bring all my members and all the posts from my old site into my new Joomla website into Fireboard forums?
We just went through a similar issue. First, we started looking at the mysql tables for the previous system and had pretty much worked out what we needed (jos_content has your posts and jos_users has your users in Joomla). But writing a migration script into CB and Fireboard looked to be rather daunting. There were obviously a few tables we weren't quite understanding. Our solution was to use Imacro (Iopus.com) and generate a script that read the old information from the mysql tables and entered them as new users (all with the same password). We then updated the passwords in the new user records with their old password (it's encoded so you can't just enter it in, but copying the db values works fine).
