New superior without new RDN

[Dave Horsfall <daveh@ci.com.au>]

OpenLDAP 2.3.32

How do I move an entry to a new superior without changing the RDN as well?  
I cannot find any examples of this (at least, none that works).

    dn: uid=dhtest,dc=coreng,dc=com,dc=au
    changeType: modDN
    newRDN: dhtest
    deleteOldRDN: 1
    newSuperior: ou=systems,dc=coreng,dc=com,dc=au
    -

Fails with:

    ldapmodify: invalid format (line 6) entry: 
    "uid=dhtest,dc=coreng,dc=com,dc=au"
    Failed to update entry.

as does:

    dn: uid=dhtest,dc=coreng,dc=com,dc=au
    changeType: modDN
    newRDN: uid=dhtest
    deleteOldRDN: 1
    newSuperior: ou=systems,dc=coreng,dc=com,dc=au
    -

I already discovered that I need "newRDN" i.e. just "newSuperior" won't
cut it.

Or must I use "ldapmodrdn", and risk a race condition if making several
changes to the same entry?
