I've done this with kermit on both machines, but it's much slower than
the floppies.  The advantage is that you can go away for the weekend
and come back with the job completed.

You just need to give kermit all the command line options to work
in pass-through mode.  Piping your cpio output to:
kermit -i -l/dev/tty00 -b9600 -s -
 with the receiving machine using:
kermit -i -l /dev/tty00 -b9600 -k
piped to a corresponding cpio on the other machine should work.

Unless you can go away for a long time while the transfer happens, I'd
just use floppies.  That way you get a backup as a side effect.
