Nordic M&A activity is gathering pace. In 2025, deal value rose across all three core markets, led by Sweden at $36bn (up 31% year on year, across around 1,070 deals), followed closely by Denmark at $32bn (up 22%, across more than 1,000 deals), with Finland growing to $10bn (up 14%).
Looking ahead, the report points to carve-outs, non-core divestments and targeted acquisitions as likely drivers of Nordic deal activity in 2026. For CIOs and IT Directors, that means executing complex data separations and integrations, often on tight timelines.
Agreeing the deal is only part of the work. Separating or onboarding enterprise data is often where the real complexity lies. Executing a smooth transition requires a migration approach tailored to the specific source and target environments involved.
1. The Four Execution Scenarios for SAP M&A and Divestitures
Depending on whether an enterprise is carving out a business unit, cloning an environment, or integrating an acquisition, SAP M&A data migrations generally fall into four core scenarios:
A. Divestment: Selective Carve-Out
Used when a divested entity represents a targeted subset of the parent organisation’s overall database. Rather than migrating the entire system, historical and master data are selectively extracted and transformed into the new target system.
B. Divestment: Clone & Delete
Deployed when the majority of the source system’s operational scope belongs to the departing entity. The complete system is cloned into the target landscape, after which data that isn’t required in the new system, such as non-relevant company codes and historical records, is deleted.
C. Logical Separation
Often required before data can be physically carved out. Logical separation splits the data within the source system itself, separating what belongs to each entity before any data is migrated.
D. Acquisitions (Buyer-Side Integration)
Contracted by the acquiring entity to onboard a newly purchased company’s data into the existing parent SAP S/4HANA landscape. This requires mapping legacy data structures (SAP or non-SAP) to match corporate governance baselines.
The right approach also depends on where the data is coming from and where it’s going, whether that’s SAP ECC to S/4HANA, S/4HANA to S/4HANA, or between SAP and non-SAP systems.
Carving Out Historical Transactions: When complex historical transactional data must be preserved and carved out into the new target entity, Selective Data Transition (SDT) serves as the primary technical methodology. SDT enables enterprise teams to migrate targeted historical tables without forcing a full greenfield or brownfield conversion.
2. Navigating Compressed Timelines and TSA Pressures
Carve-out projects often run under Transition Service Agreements (TSAs), with timelines set by the deal rather than the IT team, and little room to move them. Building a carve-out approach from scratch under that pressure adds risk.
Working with specialists who bring a proven methodology, pre-built field mapping, and ETL jobs with validation built in helps keep the migration on track within the agreed window.
Is Your SAP Architecture Ready for Deal Execution?
Whether you are preparing a business unit for a selective carve-out, managing a clone-and-delete mandate, or integrating an acquired entity into your S/4HANA environment, structural data readiness dictates your timeline.
