My favorite trick is to slave the old hard-drive to the new one.
With the advent of 8-Core processors and 64-bit systems, many desktops can take up to 4 slaves.
My latest has 3T primary (operating) drive and two [1/2T] slave drives from my previous desktops.
Buy a cable, plug & play.
No deleting, no ghosting, and you get to keep all that data in a secure place.
Yep. I do the same thing.
