Here's a method that I've used successfully in the past. (Typed from
memory however, so YMMV).

Boot into single user mode (type 'linux single' at the LILO prompt).

Mount up the new home partition, eg. under /tmp/newhome.

cd /home && tar cflp - . | (cd /tmp/newhome && tar xfp -)

The extra 'l' flag tells tar not to stray outside one partition, and
the 'p' flag tells it to keep permissions as similar as possible.

If you want to verify the copy:

cd /home && ls -lR | md5sum
cd /tmp/newhome && ls -lR | md5sum

(Check the md5sums are the same).

cd /home && find -type f | xargs md5sum > /tmp/md5sum.old
cd /tmp/newhome && find -type f | xargs md5sum > /tmp/md5sum.new

diff -u /tmp/md5sum.old /tmp/md5sum.new

(There should be no differences).
