If you go down the classic upgrade route, you definitely do not 
provision a DC, the script does it for you using information from your 
old domain.

There are two schools of thought, if you do the classic upgrade, you get 
all your users and groups etc from your old domain, along with any old 
ways of doing things (using RIDs for Unix IDs etc). The second is to 
create a new AD domain, this way you can specify just what Unix IDs etc. 
Either way has its plus and minus points.

Which ever way you go, I would suggest testing it in a walled off 
network, so you can iron out any problems before doing it for real.

Good luck ;-)
