I'm not sure how you guys are setup and if you're using IIS, Apache, etc.
Last time I moved one of these it was as simple as installing the c:\PHP folder and setting up the PHP environment and MYSQL on the new server. Backing up the Mysql DB and the website folder in wwwroot. Moving them both to the new server, moving the websiste to the new server. Then you put the database in place, and I think you change the server name in the config.php file and you're off and going.
I'd have to dig up my notes
