How do you transfer a program from one mac to another? help!

Hi,

I've got Illustrator and Photoshop, one of which I've lost the cd for, and the other which I can't be bothered to look for (I think it's in my attic - rammed full of stuff).

I want to transfer both prorams to a new laptop eventually, but until then I've just received CS3, and so want to install that now on my MacBook and so need to remove Illustrator and Photoshop onto a harddrive temporarily until my old PowerBook is back from the repair workshop next week.

I understand that I can more or less just drag the program files over, but I don't want to leave any preference files behind, so if anyone knows exactly what I need to take with me so that I don't need to reistall from the cd's, or go looking for the serial number, then I'd be very grateful.

Thanks!

 

Thanks for the advice. I'm guessing that i'll spend half a day in my attic then looking for the case - it'll teach me to be more tidy maybe!
