Moved eMac to iBook >> iBook to MacBook Pro.
Panther/Tiger > Tiger/Leopard > Leopard.
I saved all my User account including the Library to CDS & DVDs.
Made separate DVDs from within iTunes as I needed more than one.
My user account also included all 3rd party software dmgs and registration numbers for reinstall and all extra fonts.
Used command shift 4 to draw around mail and internet set up menus and saved the pngs.
Software was installed carefully over several days with a restart after every one.
Some just clone their old Mac and drop it into their new Mac, I prefer to make a totally fresh start without any of the rubbish collected over the years.
Leopard to Leopard isn't a problem.. Tiger to Leopard needs extra care as some software will not work and the Mail & mailbox set up has been changed.
Enjoy your MBP. 😉
