If you lose 16 T1 customers during a renumbering of a /20, either you
don't know how to renumber, or they were already unhappy for some
other reason.

If you tell your customers "You need to renumber because evil forces
are colluding against us," they won't be very amenable... try
explaining that they'll get better connectivity.

The social and technical problems of renumbering a /20 are nonzero but
not large.

I've done it.
