Do you mean a /16 network prefix? This would not be disruptive if the
group would wake up to the facts of life and start renumbering NOW!
Don't wait until your address allocation changes, start working on it
today and make it a part of regular maintenance and administrative
procedures. Deploy DHCP, document where IP numbers are configured,
build and test renumbering scripts, beat on vendors to make it fast, easy
and painless to renumber. 

Renumbering is not an event, it's a state of mind.
