It's actually a long time since I used it - I have only ever done a "block level" clone which copied everything to a FireWire drive (making it bootable) - and the latest version will doubtless offer additional, possibly confusing, options.
I'd suggest reading the support material and FAQ on their website before you start as the process can take quite a long time. If in doubt clone the entire installation then delete stuff afterwards.
Aloha and good luck.
