Do you still have the Aperture 2 and Aperture 3 registration codes? Then you can download the Trial installer and use that to install Aperture on your new Macbook.
You can download the Aperture 3 trial installer to reinstall Aperture from this webpage - there is a link to the trial and instructions on how to reinstall - don't let the title of this page distract you :
The Aperture 3 serial number will be available in the about panel, when you are running Aperture on your old mac (from the main menu bar: Aperture > About Aperture).
