I'm overhauling a forum that's been sitting at 3.0 and not working for quite a while now. I'd like to go with a shiny clean install, and then import the existing member list, groups and posts. (Which will then get archived, but people want access to the older content.). I don't need the theme, or any of the mods we had, just the people and conversations.
What's the best way to go about doing that? I found some old information to do with the config file, but I figured asking for current steps would be helpful.
