As we move through 2026, the enterprise software landscape has officially crossed a major threshold: for the first time, global usage of legacy SAP ECC has dropped below 50%. The “wait and see” era is over. With the December 31, 2027, end-of-maintenance deadline looming large, organizations are no longer debating if they should migrate, but rather how fast they can execute without breaking their mission critical operations. 2026 is a pressure-cooker year for companies that haven’t yet modernized their ERPs. RISE with SAP has officially cemented itself as the default migration landing zone. Rather than just doing technical upgrades, businesses are using RISE to move to a managed, cloud-first environment that simplifies infrastructure and licensing.
At the center of this massive transition is RISE with SAP, the commercial vehicle SAP is aggressively pushing to move its on-premise customer base into the cloud.
The Hard Truth About the 2027 Deadline
For decades, SAP ECC (Enterprise Core Components) has been the central nervous system for tens of thousands of global companies. However, SAP is phasing it out to force adoption of their modern, cloud-based ERP, S/4HANA. December 31, 2027 is the date SAP will officially end standard, mainstream maintenance for the most common versions of ECC (EHP 6–8). If a company was on an older version (EHP 0–5), their standard support already expired at the end of 2025.
December 31, 2030, companies that cannot migrate by 2027 can purchase “Extended Maintenance” to buy themselves three more years. However, this comes with a premium price tag (roughly a 9% markup on support costs) and is widely viewed as an expensive band-aid rather than a strategy.
What happens if a company misses the deadline?
The software will not instantly shut down or self-destruct on January 1, 2028. However, SAP will stop issuing new security patches, bug fixes, and crucially, legal and tax updates. If tax laws or payroll regulations change, the system will not update to reflect them, exposing the business to massive compliance and cybersecurity risks. Buying time until 2030 is widely viewed as a costly band-aid. Extended maintenance comes with a premium price tag roughly a 9% markup on existing support costs. More importantly, missing the 2027 deadline without a support contract means SAP will stop issuing standard updates. This does not mean the system instantly shuts down, but it does mean a halt to crucial security patches, legal updates, and tax regulation changes. Running a multi-billion dollar business on an unpatched system that cannot adapt to new regional tax laws is a massive compliance and cybersecurity liability.
“RISE with SAP” Explained
Many people mistakenly think “RISE” is a piece of software. It is not. RISE with SAP is a commercial bundle described by SAP as “Business Transformation-as-a-Service” (BTaaS). Historically, an SAP customer had to buy software licenses from SAP, rent servers from a hosting provider (or buy their own), hire a system integrator to install it, and buy separate tools for analytics. RISE wraps all of this into a single subscription contract managed by SAP.
What is included in the RISE bundle?
- SAP S/4HANA Cloud: The actual modern ERP system. Most legacy ECC customers choose the Private Edition because it offers a dedicated, ring-fenced environment that allows for more complex, legacy specific configurations than the Public Cloud equivalent (which is usually marketed to smaller businesses as “GROW with SAP”).
- Cloud Infrastructure: SAP handles the hosting, but the physical servers are provided by tech giants like Microsoft Azure, AWS, or Google Cloud. The customer chooses the provider, but SAP manages the SLA (Service Level Agreement).
- Business Process Intelligence (SAP Signavio): Before moving a messy, 20-year-old ECC system into the cloud, companies need to clean up their act. Signavio acts like an X-ray for business processes, identifying bottlenecks and showing companies how to standardize their workflows before migrating.
- SAP Business Technology Platform (BTP): The SAP Business Technology Platform is the technical foundation of the modern SAP strategy. In the past, companies heavily customized their core ECC code, making upgrades a nightmare. The new mandate is a “Clean Core.” Companies must build their custom apps, automations, and third-party integrations on BTP, keeping the core S/4HANA system pristine and easy to update.
- Embedded AI and Automation: RISE includes access to SAP’s latest innovations, including “Joule,” their generative AI copilot, which allows users to interact with their business data using natural language.
Why Some CIOs are Pumping the Brakes?
While smaller and mid-sized organizations are adopting RISE at a rapid pace driven by agility and SAP’s commercial incentives many large enterprises with highly complex, heavily customized systems are pushing back. It shifts their revenue model from one-time software purchases to predictable, recurring cloud subscriptions. For the customer, it shifts the burden of maintaining infrastructure and applying system updates back onto SAP, allowing the business to focus purely on operations.
The “Vendor Landlord” Dynamic
By moving infrastructure, licensing, and support under one single SAP contract, customers are inherently giving up a degree of control. Some CIOs are wary of being locked into a rigid ecosystem where they have less negotiating leverage over future price hikes.
Unpredictable BTP Costs
While the Clean Core strategy makes technical sense, SAP BTP operates on a consumption-based pricing model. Running heavy custom automations, massive data integrations, and AI workloads on BTP can quickly escalate cloud computing costs, making financial forecasting difficult.
The Rise of Third-Party Support
For massive organizations where a 2027 migration is physically impossible or financially ruinous, the alternative to SAP’s extended maintenance is third-party support (from vendors like Rimini Street). These vendors provide critical tax, legal, and security updates for legacy ECC systems at a fraction of SAP’s cost. This allows CIOs to extend the life of their current ERP, redirecting those budget savings into standalone AI and composable data architectures without committing to a massive RISE migration immediately.
The Bottom Line for 2026
The SAP ecosystem in 2026 is defined by pragmatism. The theoretical debates about cloud versus on-premise are over. For the majority of SAP customers, RISE with SAP represents the safest, most streamlined path to modernizing their operations, enforcing standard best practices, and natively integrating AI into their daily workflows.
However, organizations must enter these contracts with their eyes open prioritizing a rigorous cleanup of their legacy data (via Signavio and LeanIX) and carefully modeling the long-term consumption costs of their “Clean Core” customizations before signing on the dotted line.
