Will the RWM overlay make this unnecessary when it becomes stable?
It's undocumented, so I haven't tried to figure it out yet.

BTW, we have a slightly different situation: We will keep the same
suffix (dc=uio,dc=no), but will rename some trees named OU=foo,<suffix>
to CN=foo,<suffix> (along with some other reorganization).  I hope that
won't rewrite search results back to the old DNs even for search
requests that use the new DNs (or cause searches based on dc=uio,dc=no
to search both the OU=* and the CN=* trees if I use RWM).  If so, both
could be fixed by putting the old suffixes in a separate NULL database
using RWM, except if I understand overlays correctly, RWM can't refer
operations to another database.
