To move/duplicate filesystems I have a favorite way to do it locally:
# cd $filesystem_to_duplicate
# find . -print | cpio -pvdm /mnt

...where /mnt is the new filesystem/slice.
To duplicate/move across the network do it like this:
# cd $filesystem_to_duplicate
# tar cf - . | ssh otherhost "cd /$new_filesystem ; tar xf -"
