I think you may be better off using rsync for this, so that you can just copy
the files and not the filesystem, since you are moving to a larger filesystem.
Lets say you have /dev/hda4 mounted to /home.
Go to run-level 1 ( # init 1 ) and then mount /dev/hgb4 to someplace like
/mnt/new_home. then you can copying the files to the new place using:
# rsync -av /home/ /mnt/new_home/
You will need to fix the lines in /etc/fstab to get things to make sense when
you are done. I would be a good idea to have a knoppix or rescue disk on hand
to boot with in cause you get one or more lines wrong, and/or to allow you to
work with a static system.
