I am watching this amazing video of a cutover between telco systems in the 80s (which I found here somehow, but now I can't search to find it, sorry!) and now I'm wondering if the business use of "cutover" has its origins in this practice.
probably not, #etymology is rarely that tidy. Unfortunately even the OED doesn't have an entry for the business jargon sense, nor does etymonline.
But still, enjoy the cutover. My favorite part is the post-it note toward the end.

The guys with the loppers are having WAY too much fun!
@mendel You’re (AFAIK) correct! To my understanding, the term was coined within Bell in at least the 1910s or so to describe literally cutting and splicing cables for maintenance or upgrades, and came to describe any major system-level change (e.g., the manual-to-automatic exchange cutover in the 1940s).
