I have done it in the past. It is much easier to do so from a rescue disk or
the CentOS live cd, because copying from a system that is still running might
not work the best.
You can set up the partitioning on the new drive, and use your favorite poison
to copy each partition. You can use rsync, cp -a, or tar, whichever you are
comfortable with. If the drives are close in size, you can usually get away
with dd, or G4L if you want something more visual.
