I am currently using Wordpress as the blog/CMS, with the BuddyPress plugin (with bbPress Integration) for the forum/social network addon.
They are using Joomla and more specifically Fireboard component to manage their forums. Currently, there are almost 7500 members, almost 3000 forum topics with over 23,000 replies. I would like to migrate all the forum posts, users, and replies over to their new wordpress site.
