Can someone tell me exactly what needs to be done to upgrade a 6.5.5 thread install to the version 7 install?

I have copied over my forums from the current folder into a "New" folder. I also copied my database to a second one, edited all of my config files, set the directory permissions, etc. and have verified that I now have a complete test site.

In other words, let's assume you have a 6.5.5 install and configured correctly and now you want to install the latest version of 7 (currently beta3).

What exactly would you do?

Thanks,
Fred
