This is something I have done several times.  This is how I do it.  Boot
the Gentoo CD or some other live CD, Knoppix should work.  After you get
booted up, mount the partitions, old and new, then use this command:  cp
-av /path/to/old /path/to/new and sit back and watch it all scroll by. 
It may take a good while depending on how much stuff you have to copy.

I'm not saying that someone else doesn't have a better idea.  I have
seen where people tar the stuff then untar it to the new drive.  To me,
it is a useless step.  What I use has worked for me every time and I
have done it quite a bit.

I hope that helps.
