The most repeated piece of transformation advice in SAP shops right now: the 2027 ECC support cliff is a gift — a hard deadline that finally forces modernization. It sounds disciplined. The data says it's producing the opposite.

The stampede is real. The transformation isn't.

ISG's latest SAP migration study, covering 200 large enterprises, is sobering. Only 15% of migrations land on budget and on time, while 58% run both over budget and behind schedule. The reason isn't hidden: 49% of organizations plan a quick lift-and-shift with no re-engineering of legacy processes, and only 18% take SAP's greenfield route — the one path that actually redesigns processes.

We're paying premium consultants to move old workflows onto new plumbing.

A support calendar is not a strategy

A vendor's maintenance deadline doesn't tell you whether your order-to-cash process needs redesigning. It tells you when to sign a contract. Conflating the two is how "digital transformation" collapses into a version upgrade with a governance slide — the very risk-aversion ISG's Stanton Jones flagged: "By focusing on avoiding risk rather than transformation, companies miss out on the benefits."

Gartner expects roughly 17,000 organizations — nearly half the ECC base — to still be running ECC at the 2027 deadline, and about 13,000 in 2030. They aren't all negligent. Extended support at a 2% premium through 2030 is cheap next to a migration that, statistically, will blow both its timeline and its budget.

The takeaway

Decouple the two decisions. Redesign the process only if the business case clears — then migrate. If it doesn't, buy extended support and redeploy the capital where it earns a return. The worst outcome isn't missing the deadline. It's hitting it on time with the same broken processes, a bigger bill, and nothing transformed.
