Caltrade, this doesn't call for tearing down your currrent site. It's a migration type thing. Meaning you have to have the D6.1.x up and running and install a D7B8 on the same server and set up the cron job to migrate the data over for you. This may disrupt the D6 site (not sure yet as it could potentially at least tie the hell out of a server if it's a large DB) but you'll still have your D6 site when it's done. By doing it this way, Boonex is enabling you to begin testing a production form see more of the software while still holding on to your current site's functionaltiy.
