Cloud ERP Adoption Statistics (2026): S/4HANA Migration, Budgets, Testing and Skills

By the end of 2024, roughly 39% of SAP's approximately 35,000 ECC customers had licensed or moved to S/4HANA, according to Gartner data reported by CIO. Mainstream ECC maintenance ends on December 31, 2027, so this page tracks where the installed base actually stands and what it means for test planning.

Key takeaways

Migration adoption: where the ECC base stands

These figures come from different populations and different definitions of "moved," so read them as a range rather than a single answer.

• Among about 35,000 ECC customers, around 14,000 (39%) had made the move by late 2024, per Gartner's tally. CIO, 2025
• If the current pace holds, that same model leaves roughly 17,000 customers, close to half the base, still on ECC at the 2027 cutoff, and about 13,000 in 2030. CIO, 2025
• An IDC analyst puts the share of ECC users still on the older ERP through 2027 at 40% to 45%. CIO, 2025
• A Forrester internal analysis, as relayed by Qyrus, finds fewer than half of ECC clients on track to finish by 2027. Qyrus, 2026
• Of 296 organizations surveyed between December 2025 and March 2026, 55% had S/4HANA deployed in some form, but only 34% had finished the overall transformation. SAPinsider via Datapace, 2026
• In ASUG's 2026 "Navigating SAP S/4HANA" research, 68% of the 194 members polled were live or actively moving off ECC. Diginomica on ASUG research, Oct 2026
• An earlier ASUG study built with BearingPoint, drawn from 168 members, counted 56% as live or in progress, 11 points above the year before. ASUG, 2025
• In DSAG's 2026 investment report, 37% of German-speaking user group companies still on ECC expected to be on S/4HANA by end-2027. Arkyn summarizing DSAG, Oct 2026

Cost and budget

• When ASUG's 2026 Pulse survey asked about the hardest parts of migration, budget (61%) and integration (48%) ranked highest. Arkyn on ASUG Pulse 2026
• Panorama Consulting's 2026 ERP Report, which covers ERP projects across vendors rather than SAP alone, found that more than a quarter of organizations went over budget, most often because they needed additional technology. Panorama Consulting, Mar 2026
• In the Precisely and ASUG study released in November 2025, the top barriers were business process change, customizations and organizational resistance. Precisely/ASUG via PR Newswire, Nov 2025
• SAP's management told analysts on its Q2 2026 call that its migration toolchain can cut ERP migration costs by up to 30%. This is a vendor claim we could not verify independently. Investing.com transcript, Q2 2026

Timelines and deadlines

• Mainstream support for ECC stops at the end of 2027. Extended support through 2030 is available at a 2% premium, according to The Register's reading of SAP's terms. The Register, Feb 2026
• Enhancement Packages 0 through 5 already lost mainstream maintenance at the close of 2025, while Packages 6 through 8 keep it until the 2027 date. Incorta, 2026
• ASUG members who had transitioned averaged about a year and a half for the move. ASUG, 2025
• A migration-services guide puts typical projects at 12 to 24 months, stretching to 18 to 36 months for complex manufacturers. Doodex, 2026

Read the timeline numbers with care. The 1.5-year average comes from a member survey of people who had already moved. The 12-to-36-month ranges come from vendor guidance. Neither is a project-level benchmark for your own landscape.

Failure and risk

• ISG's February 2026 research, based on 200 senior decision-makers, found close to 60% of SAP migrations overran both schedule and budget. The Register, Feb 2026
• Fewer than one in five organizations rebuilt SAP processes when they moved to S/4HANA. Nearly half (49%) did little or no re-engineering and kept legacy processes and data. The Register, Feb 2026
• ISG's early-2026 tally of migration approaches found bluefield hybrids to be the most common path. Software Modernization Services citing ISG, 2026
• ISG warns that brownfield and hybrid routes can make later AI adoption harder because they carry fragmented processes and legacy data structures. Software Modernization Services citing ISG, 2026

Testing and quality

Capgemini's World Quality Report 2025 sampled more than 2,000 executives across 22 countries. Its findings on generative AI and test automation are the most-cited testing numbers in the market.

• Of the respondents, 89% were piloting or deploying GenAI-augmented quality engineering workflows. Of those, 37% had reached production and 52% were still in pilots. Capgemini, Nov 2025
• Only 15% had reached enterprise-wide implementation. Another 43% were still experimenting and 30% ran limited use cases. Capgemini WQR 2025-26
• The share of organizations that had not adopted GenAI in testing fell from 31% in 2023 to 4% in 2024, then rose to 11% in 2025. Capgemini, Nov 2025
• Around 60% of organizations struggle to provision secure, scalable test data, and 58% cite challenges adopting AI-powered testing tools. Capgemini WQR 2025-26
• Average use of synthetic test data climbed from 14% in 2024 to 25% in 2025, and the report ranks it as the top GenAI use case. Capgemini WQR 2025-26
• Nearly half of organizations were still planning their test automation, and automated coverage averages about a third of test cases. Sogeti, World Quality Report 2025-26

People and skills

• Generative AI ranked as the top skill for quality engineers, cited by 63% of respondents, ahead of core quality engineering skills at 60%. Capgemini WQR 2025-26
• Soft skills, both verbal and written, ranked fifth, with 51% of respondents calling them critical. Capgemini WQR 2025-26
• Among members of the UK and Ireland SAP user group, 92% see talent scarcity as a brake on migration pace. Resident, June 2026

Cloud ERP market and SAP's cloud momentum

• SAP's current cloud backlog reached €22.9 billion in Q2 2026, growing 27% as reported and 26% at constant currency. SAP Quarterly Statement Q2 2026
• Cloud ERP Suite revenue rose 25% (27% at constant currency) to €5.5 billion in Q2 2026. SAP Quarterly Statement Q2 2026
• That suite accounted for 88% of SAP's total cloud revenue for the quarter. Investing.com, Q2 2026
• By Q3 2026, the backlog had grown to €24.1 billion, up 28% as reported, while Cloud ERP Suite revenue increased 29%. SAP Form 6-K, Q3 2026
• An Anchor Group figure cited in a 2026 ERP statistics roundup puts cloud-based deployments at 70.4% of ERP installs. KreativeCore citing Anchor Group, 2026
• In Europe, 46.45% of enterprises with 10 or more employees used ERP software in 2025, per Eurostat data reported by Axis Intelligence. Axis Intelligence citing Eurostat, 2026

Source: Investing.com, Q2 2026; KreativeCore citing Anchor Group, 2026; Axis Intelligence citing Eurostat, 2026. The three measures cover different scopes and are not directly comparable.

AI in migration and delivery

• SAP said more than 90% of its 50 largest deals in Q2 2026 included AI and Business Data Cloud as key elements. Investing.com transcript, Q2 2026
• One customer example SAP presented: a RISE migration that removed 97% of legacy customizations and produced a 75% faster accounting close. This is a single vendor-reported case, not a sample. Investing.com transcript, Q2 2026
• Almost a third of SAP customers are discussing AI without a meaningful strategy, according to ASUG's October 2026 analysis. Diginomica on ASUG research, Oct 2026

Where the numbers conflict

• Share on S/4HANA. Gartner's 39% counts ECC customers that had licensed or moved by end-2024. The 55% and 68% figures come from SAP-focused survey panels, so they measure deployment or membership, not the whole base. Use the 39% as the base-wide floor and the survey numbers as a sentiment check.
• The 2027 outlook. Gartner-based modeling expects about 17,000 customers still on ECC at the cutoff. IDC expects 40% to 45% still on the legacy system through 2027. Forrester's internal view, as relayed by Qyrus, is that fewer than half will finish by then. A separate model cited by Software Modernization Services puts the live share near 57% by end-2027.
• Budget overruns. ISG reports close to 60% of SAP migrations overran. Panorama reports that more than a quarter of ERP projects overran, across all vendors. ASUG reports 3% under budget. These measure different things: ISG focuses on SAP migrations, Panorama on all ERP projects, and ASUG on a member sample.
• Cloud share of ERP. The only cloud-share figure we could trace to a named source in this roundup is Anchor Group's 70.4%. We did not find a Panorama figure we could verify directly on this topic.
• Vendor data. SAP's 30% migration-cost reduction and the Dexco case are vendor-reported. We have labeled them as such and do not use them as market benchmarks.

What this means for your sign-off

• Put the 2027 date into your entry criteria. If your program has not reached integration testing by mid-2027, the extended-support decision belongs in the go/no-go record. See ECC end-of-maintenance dates and what they mean for your plan.
• Plan for test data first. With 60% of teams struggling to provision secure, scalable test data, data strategy is a sign-off item, not an afterthought. Read Test data for S/4HANA: copies, masking and synthetic data before you lock the test environment plan.
• Staff for the talent squeeze. With skill scarcity cited by 92% of members in one UK and Ireland survey, build a testing center of excellence that outlasts a single vendor's team. The SAP Testing CoE operating model covers roles, RACI and funding.
• Budget for the failure mode, not the plan. Almost six in ten migrations in the ISG research overran. Hold contingency for scope and integration, the two causes most cited in ISG and ASUG data.
• Treat AI as a test-scope question. Only 15% of organizations have scaled GenAI in quality engineering. Require evidence for every AI-generated test asset before it enters the regression suite.
• Re-test on the cloud cadence, not the project cadence. With SAP's cloud backlog rising 27% and RISE deals spreading, expect quarterly change after go-live. Read RISE with SAP: what it includes, and why testing is still your job to see where that responsibility sits.
