Flash-cut
Encyclopedia
A flash-cut, also called flash-cutover, is an immediate change in a complex system, with no phase-in period.
Some telephone area codes were split immediately, rather than being phased in with a permissive dialing
period. An example is telephone area code 213
, which was split into 213 and 714

, or W39CO
.
A flash-cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period.
