Emails to new computer

Hey, first of all, sorry if this isn't the right place to ask on the forum.

I just bought a new macbook pro and i want to import all my old mails(and mailboxes) from my old Macbook to the new one. How does one do that? Is there a folder somewhere like the itunes/iphotos one i just need to copy/paste onto my external harddrive or is there a smarter and quicker way to do this? It's ALOT (past 6 years) of emails i need to move, if that makes any difference.

I have, but my old Macbook doesn't seem to be very cooperative..
