If you would like to migrate everything from the old MacBook Pro to the new one, you should use Migration Assistant. Follow the instructions at the Apple Support page Move your content to a new Mac. In a nutshell, assuming that both computers are running OS X 10.9 or later:
- Connect both MacBook Pros to the same WiFi network OR connect them together directly via Thunderbolt or Firewire.
- Open Migration Assistant on the new MacBook Pro select the first option to move your content from a Mac.
See the linked support page for further details.
