You mean Virtual Private Server(VPS) right? Definitely look into what they do on there end as far as the setup and configuration. I think VPS's allow you to have more control over server configurations similar to dedicated servers but I'd want to make sure I didn't get stuck with something that required extra configuration on my part unless I was used to setting up servers.
Also, business plans usually have a few less customers on them than the basic shared hosting plans so they aren't as bogged down.
I'm a hostgator fan so I couldn't say much else about godaddy other than to say I think they are similar in there business plans and VPS
I'd contact their support on the phone or through chat and confirm what you get and what they do as part of the change over to get you up and going.
