Hi Javid, there is a method that could POSSIBLY work..and this is a giant possiblity.
You'll need 2 servers to do it, and it's apparantly extremely tricky - i've never done it personally, but a mate of mine at work has. It's called a "Swing Migration"
The biggest problem you'll face is having SBS on a network with another Domain Controller...it just doesn't work...so the Swing Migration gets around this...I'm not sure of the specifics...but you'd be able to find all sorts of information now that you have a possible method
