Cloning new HDD for late 2009 Mac Mini

Hi guys,
Firstly sorry for starting a new thread, but I can't find an answer to my question in the Forum.
I have an 2011 MBP. I recently purchased a late 2009 Mac Mini to serve as the Media Hub and work station for the rest of the family.
As it comes with the stock 160GB 5400 HDD, I want to replace it with a 750 GB WD Scorpio Black.
Both are running Mavericks.
I have all users set up on my MBP and would like to transfer this to the Mini and have both machines identical.
Do I:
a. Clone my MBP drive to the new HDD and will an '09 Mini boot from this? (Same OS build for all MACS)
B. Clone the Mini's HDD to install Mavericks AND then use Migration Assistant?

Thanks!

Thanks!
That was fast!

Thanks BigRed 1, I think I may try to clone the drive first, as our broadband speeds aren't fantastic and it took quite a while to download Mavericks. But thanks for the reply and also glad to see, I wasn't too far off the mark!
