There also is the problem of clients that have the IP addresses of
the name servers buried inside TCP/IP configurations, and those
name servers are referenced by IP address.  All of the local clients
of the DNS servers whose IP addresses are changing will have to
change the IP addresses in the TCP/IP configurations.
