question: just installed new hard drive

Hi, i just installed a new hard drive on my 13" aluminum macbook. My brother has a macbook he hasn't been using so what I did was use the migration assistant and transfer everything to his macbook before I did the hard drive upgrade.

The question is, would I be able to just use migration assistant to transfer everything back? Any help would be greatly appreciated. You guys are awesome! Thank you

Yeah, after you reinstall Mac OS X (during the flashy movie and registration setup), you'll have the option to transfer the data that Migration Assistant copied.
