Enterprise leaders challenge mandatory ERP upgrades, exploring composable architectures and cloud-native alternatives aligned with business strategy.
SAP's 2027 mainstream support deadline for ECC systems is prompting CIOs to reconsider mandatory migrations to S/4HANA with industry experts increasingly advocating for alternatives including modernized legacy systems, composable architectures and cloud native ERP platforms. The shift reflects growing skepticism about whether wholesale ERP upgrades serve organizational needs or primarily benefit vendors.
Kingfisher's decision to reject S/4HANA migration in late 2025 expands this reassessment. The retail giant opted instead to modernize its ECC system on Google Cloud with support from Rimini Street, adding AI, personalization and recommendation engines at a fraction of traditional migration costs. The approach has already delivered measurable benefits demonstrating viable alternatives to expensive, disruptive transformations. "At some point, they will have to make a move but they've given themselves breathing room at a fraction of the cost," said John Burns, senior director of financial systems and controls at Summit BHC who specializes in ERP transformations. "CIOs should assess SAP's roadmap the same way they evaluate any other business decision by asking whether it makes sense."
The business case for S/4HANA migration remains contested. While SAP promises AI automation, improved scalability and future innovation, cost uncertainties, loss of customizations and implementation disruption are making transitions difficult to justify. Burns emphasizes that complete implementation requirements create risk and expense that may not align with organizational strategy.
"The era of a single monolithic ERP trying to manage every function is being replaced by agile, modular platforms that better reflect how businesses work in an increasingly dynamic world," said Amit Basu, CIO and CISO at International Seaways. Basu advocates a phased modernization approach recommending CIOs assess flexibility, long term cost transparency and alignment with digital strategy rather than pursuing mandatory upgrades.
"The trend is moving toward keeping a strong financial core and extending capabilities through specialized modules rather than relying on a single monolithic system," Basu stated. Burns reinforces this perspective: "Seeking alternatives to SAP should not be seen as a drastic move," emphasizing that practical decision making should supersede vendor driven timelines.
