Transfer iTunes Library and iPhone Sync data from old iMac to new Macbook Pro

Hi,

I bought a macbook pro in September last year, previous to this I had an iMac. This has all my music and iTunes stored on it.

Is there a way to transfer my iTunes over to my new Macbook Pro and sync my iPhone as if my phone thinks it's the same computer, so I don't have to restore my phone or set it up as a new one.

Thanks.
