Plenty of enterprise data migrations get declared a success at go-live, only to be quietly admitted as failures six months later. The cutover banner goes up, the integration team disbands, and everyone celebrates. Then reality sets in. Financial reports fail to reconcile, business units lose…
On AT&T’s Q2 2026 earnings call, CEO John Stankey said, “We’re converting market-by-market, and we’re pretty much getting to the back end of that now,” referring to the integration of systems from AT&T’s acquisition of the Mass Markets fiber portion of Lumen Technologies’ business. All…
