Boot camp install from a HDD image

Question

How would one go about imaging an old work computer (old IBM aptiva from 2001ish) with Windows XP and lots of stuff (VPN client with settings etc) to a new iMac, while preserving Mac OSX? I can't simply install XP on the iMac and then reinstall/copy across stuff; it NEEDS to be an image.

Can you even image smaller HDD's and then place them on large ones, or do they have to be the same size?

Recommendations on how I go about this?

Edit: It MUST be boot camp. I don't want to virtualize it from within OsX

Answer 1

If the Mac is new enough, go with a Virtual PC setup of XP, inside OS X (VMWare, VirtualBox, etc.).

That way you can use the image without needing to use Boot Camp.
