Just use the Unix mv(1) command on an NFS client. Since 6.4, rename(2)
across qtree boundaries works in the common case of a non-directory
with link count 1. Provided your mv(1) doesn't have false "optimisations"
about how to do a recursive move, the operation will be mostly rename's
and comparatively little copy-and-then-delete-old.

See Tom Haynes' posting on 2003-04-01 [*] in the thread "converting a 
directory to a qtree" in the toasters archives for more details.
