Importing from VB3.8...
 

I have a vB3.8 site, but I've done a metric ton of modifying to the database. I would like to start a new vB4.0 version of my site with a relatively clean slate. What I mean is that I want to keep all the default content: the users, posts, forums, usergroups, etc... but I want it to completely throw out ALL modifications I have made, so when I set up the new vB4.0 site, it will be as if it is a vB4.0 forums, without modifications, that has been up for 2 years now... without modifications.

Is this how impex works?
