"tar" can do it.

something like

 (cd /mnt/part1 ; tar clf - ) | ( cd /mnt/part2 ; tar xfv - -p )

some of the options explained....

       -c, --create
              create a new archive

       -l, --one-file-system
              stay in local file system when creating an archive

       -f, --file [HOSTNAME:]F
              use  archive file or device F (default "-", meaning
              stdin/stdout)


       -x, --extract, --get
              extract files from an archive

       -v, --verbose
              verbosely list files processed

       -p, --same-permissions, --preserve-permissions
              extract all protection information
