Step-by-step OS X migration

[xchaotic]

I am about to upgrade my existing Macbook (old one) to previous gen Mac Book Pro.
My existing HDD is 120GB, new is 200GB, I'd like to split that into the same 120 GB and 80GB for WinXP through bootcamp.
I currently can't decide whether I want to migrate my existing system with loads of software or start fresh again, I don't mind either way.

Can you help me with a simple way to do the migration painlessly?
(I don't mind a bit of command line)

The manufacturer of said notebooks has some tips and tricks on migration on its support page.

Thanks.

It seems that it indeed is a very, very easy thing to do.
Is it really all going to work so seamlessly, all my installed applications etc?
