If you have a router you can connect the two in a small network using CAT-5 network cable.
Or if you have an external HDD transfer your files to that, then transfer over to the other system.
And I think, but Im not sure, that this works too. If you just direct connect the two together using network crossover cable and go to Files and settings transfer wizard under system tools you can do it. This would be the best option if you want to transfer everything.
