System Administration Guide: Naming and Directory Services (FNS and NIS+)

Do not change the name services currently provided by NIS or change the way NIS functions.
Do not change the structure of DNS.
Do not change the IP network topology.
Do not upgrade applications that use NIS to NIS+; leave the migration to NIS+ APIs for the future.
Do not consider additional uses for NIS+ during the implementation phase; add them later.
