I posted a walkthrough of this on the main Joomla site, but thought it might be worth posting here, as well.

The migration from MDForum to fireboard using the phpbb converter listed in the forum caused some problems, because it wasn't importing the email addresses, and wouldn't let new users post to the forum until after they logged in to their account and inserted their email addresses. The reason for this is that the emails aren't stored in the md_phpbb tabels, they're stored in the md_users database, which is different from what you would see in a straight phpbb->fireboard conversion. That's the bad news. The good news, is that I've figured out how to modify the PN user Converter to work with MDPro. The problem was that the script listed above was searching for the wrong table name. What you need to do is open up the ConvertPostNukeUsers.php file and change all instances of "nuke_users" to "md_users", (or what ever your MDPro/Postnuke users database is called). I believe this change will also work for the stories and topics in the other file included here, but I haven't fully tested it yet. [Edit: Tested and works!]

Ok, here are the steps to convert users, news stories, topics, and forum posts from MDPro to Joomla

1. Download and unzip the gn_ConvertMDPro file below.

2. Export your md_users, md_topics, md_stories, and all "md_phpbb" tables from your MDPro database, and then import into your joomla database.
3. Change the parameters for localhost, dbname, dbuser, and dbpassword to reflect your site, (if your MDPro site's sql database uses a prefix other than "md", you'll need to change all instances of "md_users" "md_stories" and "md_topics" to reflect your MDPro prefice.
4. Upload the ConvertPostNukeUsers.php and ConvertPostNukeContent.php to your joomla install
5. Run through the test for the users, stories, and topics conversion.
6. If everything is more or less ok, change the "test" mode to false and re-run the users and stories converters.
7. Install fireboard on your joomla installation.
8. Download the phpbb to fireboard converter listed below:
www.bestofjoomla.com/component/option,co...t,10/limitstart,180/
9. Change the parameters of the converter to reflect your database login info as well as your mdforum usertables.
10. Run the converter.
11. Delete the extra tables and the mdpro converters from your joomla installation.

And the should be it. You can look at www.joomla.tianjinexpats.net for an example. It's just a testing site, so that isn't the full deal. However, you can see the news posts on the front page as well as click to go to the forum up at the top.

...I should add that this was tested using MDPro 1.076. It should work with MDLite as well, from glancing at the md_users database, but I haven't tested it yet.

I realize that not that many people use MDPro, but for those of you who do, this is worth looking into, if you're thinking about converting.
