SAP Moves Nokia ERP Workloads to Microsoft Azure in Cloud Migration Deal

Nokia has signed a multi-year agreement with SAP to migrate its core ERP to SAP S/4HANA on Microsoft Azure using the RISE with SAP methodology, marking a significant enterprise cloud migration deal. The move reflects continued momentum in large-scale ERP cloud migrations as enterprises modernize their core business systems.

The deal was announced July 1, 2026, following an agreement concluded at the end of 2025, and represents a partnership between 3 major technology companies: Nokia, SAP and Microsoft.

Last updated August 4, 2026: added the real driver behind this deal's timing, SAP's December 2027 end-of-support deadline for its older ECC platform, and how far behind the broader ECC customer base is on migrating, context missing from the original report.

What Happened: Nokia's SAP-to-Azure Migration

Nokia is moving a broad slice of its SAP landscape to SAP S/4HANA on Microsoft Azure, covering central finance, Master Data Governance, Extended Warehouse Management, Global Trade Services, and the cloud edition of S/4HANA for advanced available-to-promise, together touching finance, supply chain, manufacturing and HR processes. SAP will operate and manage Nokia's environment within SAP-owned Azure subscriptions as part of the RISE with SAP offering, which bundles the migration methodology, tooling and managed services.

Microsoft and SAP have a longstanding partnership around cloud ERP, with Azure being a certified platform for SAP workloads. Nokia's migration validates this joint offering for large-scale manufacturing and technology companies. Microsoft's Joacim Damgard described the project as bringing "SAP S/4HANA, Azure, and RISE with SAP together," while SAP's Manos Raptopoulos said the engagement gives Nokia a "structured road map and integrated toolchain for the migration." Nokia's Marek Očkay said the agreement builds on the company's existing work to "simplify its ERP landscape."

Key Details

SAP ERP migrations to cloud platforms are complex projects that typically take months or years to complete. They involve moving critical business data, reconfiguring integrations, and often re-engineering business processes to take advantage of cloud capabilities.

Azure offers specific services optimized for SAP workloads, including certified virtual machine configurations, high-availability architectures, and direct network connectivity options. These capabilities are designed to meet the performance and reliability requirements that SAP users demand. SAP has also said AI-enabled functions embedded in its cloud applications will be adopted gradually as part of the engagement, though it has not detailed specific AI use cases, timelines or expected outcomes. The financial terms of the multi-year agreement have not been disclosed.

Why Now: The 2027 Deadline Behind the Timing

This deal isn't just opportunistic cloud modernization, it's timed against a hard deadline. SAP has confirmed mainstream support for its older ECC platform ends December 31, 2027, with no further extensions; after that, no more security patches or compliance updates. As of late 2024, only around 39% of ECC customers had licensed S/4HANA, meaning more than 60% of SAP's ECC customer base still needed to move. With migrations typically taking 18-36 months, and industry analysts warning that SAP talent, hyperscaler capacity, and migration partners will all face surging demand by late 2026 as the deadline approaches, Nokia's July 2026 move looks less like early adoption and more like getting ahead of a capacity crunch that will squeeze companies who wait.

The technical shift from ECC to S/4HANA is more than a rebrand: ECC runs on a traditional relational database architecture, where transactional and analytical data are typically stored and processed separately, while S/4HANA is built around SAP's own in-memory HANA database, which keeps far more data directly in RAM rather than on disk and lets transactional and analytical queries run against the same live dataset. That architectural change is what enables the kind of real-time reporting and embedded analytics SAP markets as S/4HANA's core advantage, but it also means a migration isn't a simple lift-and-shift: existing custom code, integrations, and business processes built around ECC's older data model often need to be reviewed, adapted, or rewritten, which is precisely the complexity RISE with SAP is packaged to manage on the customer's behalf.

Why It Matters

Nokia's decision sends a signal to the roughly 60% of ECC customers who haven't started migrating: waiting means competing for the same shrinking pool of migration talent and hyperscaler capacity as the 2027 deadline nears, likely at worse pricing since conversion credit percentages decline as the deadline approaches. For Microsoft and SAP, winning a company of Nokia's scale and complexity is a reference case they'll use to court the large remaining pool of enterprises still facing this same deadline pressure.

What Happens Next

The migration will proceed in phases, with Nokia likely sequencing non-critical workloads before core financial and supply chain processes. The more consequential story to watch is whether the predicted late-2026 capacity crunch materializes, and how the roughly 60% of still-unmigrated ECC customers fare as the December 2027 deadline gets closer with less migration capacity available to serve them.

Final Takeaway

Nokia's SAP-to-Azure migration validates cloud ERP for large enterprises, but the more important context is the clock it's racing against: a hard December 2027 end-of-support deadline that the majority of SAP's ECC customer base hasn't yet addressed, with migration capacity likely to tighten as that date approaches.

Key Points

Cloud ERP Migration Challenges

Moving SAP ERP to the cloud is 1 of the most complex IT projects an organization can undertake. ERP systems are deeply integrated with business processes, custom code, and third-party systems. Each integration point must be evaluated, modified, and tested during migration.

Nokia's experience as a technology company should provide advantages for this migration. Unlike organizations where IT is a support function, Nokia has deep technical expertise that can be applied to the migration project. However, even technology companies face challenges when migrating mission-critical systems that support global operations.

Microsoft and SAP have invested heavily in making Azure a certified platform for SAP workloads. This includes specific virtual machine configurations, high-availability architectures, and direct connectivity options. These investments reflect the strategic importance of SAP workloads to both companies.
