SAP S/4HANA vs SAP ECC: What Indian Enterprises Must Know Before 2027 End of Support
As the 2027 end-of-support deadline for SAP ECC approaches, Indian enterprises – from MSMEs to large corporations – must start planning their SAP ECC to S/4HANA migration. SAP S/4HANA is SAP’s next-generation ERP suite designed exclusively for its in-memory HANA database. Unlike SAP ECC (ERP Central Component), which can run on various databases (Oracle, IBM, etc.), S/4HANA runs only on SAP HANA. This fundamental shift enables S/4HANA to deliver real-time analytics and much faster performance: it loads data into memory (column-based tables) with no need for legacy aggregates, so queries execute in real-time. In short, S/4HANA streamlines SAP’s traditional data model (for example, combining Finance and Controlling into a single “Universal Journal” table) and replaces separate customer/vendor ledgers with a unified Business Partner model. These innovations (plus a modern SAP Fiori user interface) make S/4HANA far more agile and efficient than legacy ECC. In addition, S/4HANA offers flexible deployment (on-premise or cloud) and new modules (like Embedded SCM and Advanced ATP) that ECC lacks.
- Database & Performance: ECC runs on traditional RDBMS; S/4HANA runs only on HANA’s in-memory database, yielding much faster data processing and real-time insights.
- Simplified Data Model: S/4HANA merges the FI and CO modules into one Universal Journal (ACDOCA) and eliminates redundant tables (e.g. material ledger and inventory tables are streamlined). This reduces complexity and data footprint.
- User Experience: S/4HANA uses SAP Fiori for a modern, role-based UI, replacing ECC’s older GUI. The Fiori apps are intuitive and mobile-friendly.
- Integrated Processes: S/4HANA integrates customer and vendor data into a single Business Partner master record, and brings advanced planning (e.g. integrated IBP, embedded APO functions) and analytics into the core.
- Cloud-Ready: S/4HANA is available on-premise, private cloud, or public cloud (S/4HANA Cloud editions), whereas ECC was traditionally on-premise only. This allows Indian businesses to adopt SAP’s RISE cloud offerings if desired.
In essence, S/4HANA is not just an upgrade but a re-engineering of SAP’s ERP. It abolishes many old bottlenecks (like batch MRP) and replaces them with real-time, intelligent processes. As one analyst notes, delaying this transformation “limits a business’s ability to streamline operations, gain insights, and drive innovation”.
2027 SAP ECC End-of-Support: Implications for Indian Businesses
SAP has announced that mainstream maintenance for SAP ECC will end on December 31, 2027. After this date, SAP will no longer provide regular patches, updates, or legal changes for ECC. Recognizing migration challenges, SAP offers extended maintenance from 2028–2030 at a 2% annual premium on maintenance fees. Even beyond 2030, only customer-specific support (essentially “break/fix” service without enhancements) will be available.
For Indian enterprises, the 2027 deadline means planning their SAP upgrade 2027 strategy now. According to industry research, this deadline is the primary driver behind the recent surge in S/4HANA migrations. Companies still on ECC must either migrate or pay substantially for extended support. Missing the deadline could expose them to unsupported software risks. In practical terms:
- No New Updates: Post-2027, SAP will not release new functionality, performance improvements, or regulatory updates for ECC. (This could impact compliance with future tax or GST rules in India.)
- Higher Costs: Extended support costs extra (SAP charges a ~2% fee premium). Delaying migration might mean paying this higher maintenance for years.
- Limited Support: After 2030, even extended support ends; only ad-hoc fixes are provided. Businesses may face “customer-specific maintenance” with no software enhancements.
- Strategic Shift: SAP has committed to innovating on S/4HANA through 2040, but legacy ECC will not benefit from these innovations. Indian companies that skip S/4HANA could lose out on future SAP enhancements.
Given these implications, Indian enterprises should treat 2027 not as “far away” but as an urgent deadline. As a recent report emphasizes, the upcoming end-of-maintenance is the most important factor pushing customers toward S/4HANA. To avoid last-minute rush and risk, planning must start today.
Risks of Delaying SAP Migration
Delaying the switch from ECC to S/4HANA can be very risky. Key risks include:
- Technical Debt & Security: Legacy ECC systems will accrue “technical debt”. They become increasingly fragile and insecure without updates. Security patches will stop, raising the risk of vulnerabilities.
- Higher Costs: Waiting may force you to pay for costly extended support. Meanwhile, integrating new digital tools (AI, IoT, cloud) into an outdated ERP often costs more than adopting a modern platform. In fact, the cost of retrofitting legacy ECC for AI/IoT can surpass the cost of moving to S/4HANA.
- Talent Shortage: SAP experts are focusing on S/4HANA. The longer you stay on ECC, the harder (and more expensive) it may become to find skilled consultants or employees, as those resources dwindle.
- Competitive Disadvantage: Without S/4HANA’s real-time analytics and agility, companies risk falling behind competitors. Legacy ERP “limits a business’s ability to adapt to evolving needs” and can put firms at a disadvantage.
- Regulatory & Functional Gaps: New business requirements (like e-invoicing, GST updates, or fintech integration) may not be supported by old software. S/4HANA offers built-in compliance updates and modern finance features to handle such needs.
For example, a study found that enterprises delaying S/4HANA adoption struggle to secure ERP/SAP talent without paying a premium, underlining the urgency of migration. In short, postponing migration only piles up risk: you’ll still need to upgrade eventually, but on a tighter timeline, likely at higher cost and stress.

Frequently Asked Questions
A: SAP S/4HANA is SAP’s intelligent ERP suite launched in 2015, built to run only on the SAP HANA in-memory database. Unlike SAP ECC (the older SAP Business Suite), S/4HANA offers a simplified data model (for example, combining finance and controlling into a universal journal), real-time analytics, and a modern Fiori user interface. These changes make S/4HANA far faster and more flexible than ECC. By contrast, ECC can run on various databases and lacks many of S/4HANA’s embedded innovations (such as advanced supply chain planning and AI-driven analytics).
A: Mainstream support for SAP ECC (ERP 6.0) ends on December 31, 2027. After that, SAP will provide only optional extended maintenance (2028–2030 at an extra cost). Without extended support, companies will move to customer-specific maintenance with no new feature updates. In practice, this means Indian businesses should plan to migrate before 2028 unless they are willing to pay for extended support and accept limited future enhancements.
A: Remaining on ECC exposes a business to several risks. You’ll miss out on SAP’s new features and efficiency improvements. Security patches and tax law updates will stop (critical for compliance with India’s regulations). You also risk higher costs: extended support fees are costly, and integrating new digital technologies into an aging system is usually more expensive than moving to S/4HANA. Analysts warn that delaying migration leads to “technical debt,” making systems harder to upgrade later. Finally, competitors moving to S/4HANA may gain an edge with faster processes and advanced analytics that you won’t have.
A: There are generally two main paths: Brownfield (system conversion) and Greenfield. Brownfield means converting your existing ECC system into S/4HANA; it preserves customizations but can be complex. Greenfield is a fresh implementation of S/4HANA, building anew and often simplifying processes. A hybrid “Bluefield” (selective migration) approach can also be used. The best choice depends on your business. PTS Systems can help you choose and execute the right strategy, using SAP’s Readiness Check tools and the Activate methodology to guide the project.
A: Migrating to S/4HANA is a major project; typical timelines range from 9–18 months depending on scope and complexity. Key phases include discovery, planning, design, data migration, testing, and go-live. Costs vary widely based on system size, customizations, and chosen deployment. However, compared to the risks and expenses of extended support on ECC, investing in an upgrade often yields a strong ROI through efficiency gains. PTS Systems provides detailed quotes after an initial assessment, and we work to optimize the project timeline and budget.
