Across the Nordics, and particularly in markets like Sweden, Denmark, and Finland, a quiet urgency is building inside enterprise IT departments. With SAP ending mainstream support for ECC in December 2027, Nordic organisations are deep in the planning stages of one of the most complex technology transitions.
Compounding this pressure is the fact that SAP’s Compatibility Packs for S/4HANA on-premises officially expired in May 2026, removing a crucial bridge that allowed legacy ECC functionality to run in new S/4HANA environments.
While most conversations focus on the technical migration path (greenfield vs brownfield vs hybrid), a foundational question is often deferred until it is too late: what happens to the decades of data in your current SAP system?
For Nordic enterprises serious about a successful S/4HANAtransformation, pre-migration data archiving is not just an administrative task; it is one of the most strategic decisions they will make.
The Scale of the Legacy Data Problem
Many organisations approach an S/4HANA migration with a structured plan for system conversion, but they defer the data question entirely. The reality of enterprise data volumes makes this a costly mistake:
- Unsustainable Growth: Analysis of over 300 SAP systems reveals an annual data growth rate of 20–40%.
- Decades of Debt: Many systems contain data that has never been archived since go-live, sometimes dating back 15 to 20 years.
- Costly Consequences: Because SAP S/4HANA’s in-memory database is licensed on a volume basis, migrating unnecessary historical data directly inflates licensing costs.
Organisations that migrate without archiving face longer downtime windows, highly complex cutovers, and a much higher risk of data quality issues.
For example, when Swedish retail giant Coop migrated two business-critical ECC systems (holding 56TB and 8TB of data, running for up to 20 years without archiving), the sheer complexity of the legacy data required a highly advanced Near-Zero Downtime methodology.
What SAP Data Archiving Actually Does
To support a Clean Core in 2026, the data migrated into your new S/4HANA environment should be high-quality and right-sized, with obsolete, redundant, and low-business-value historical data kept out of the operational core where appropriate.
Data Archiving is a key enabler of the data dimension of Clean Core because it reduces data volume, cost, and migration/upgrade risk – but Clean Core also depends on standardized processes, decoupled extensions, stable integrations, and effective operations.
- It is accessible but read-only: SAP Data Archiving moves inactive or historical data out of the live production system and into structured archive storage. The data remains accessible for audits, compliance, and reporting, but it no longer burdens the active database or inflates the migration scope.
- It enables compliance: Information Lifecycle Management (ILM) frameworks allow organisations to define precisely which data stays online, what moves to the archive, and how it can be retrieved. This ensures strict compliance with retention requirements under GDPR, tax law, and audit obligations across Sweden, Denmark, and Finland.
The Nordics Context
The Nordic ERP market is expanding rapidly, projected to reach USD 2.76 billion by 2031. However, executing a migration in this region requires navigating highly specific local challenges:
- Strict Data Sovereignty: Nordic procurement teams are heavily scrutinising where data lives and who controls it. Denmark’s central procurement body has elevated data security concerns above sustainability in bid evaluations, and the country has even recommended organisations avoid US cloud services.
- Active GDPR Enforcement: Regulatory bodies in the Nordics are actively enforcing data protection laws, as seen when Finland’s data protection authority issued a €1.1m fine in 2025. Structured archiving ensures compliant data retention and prevents these costly exposures.
- The Talent Shortage: A March 2025 survey highlighted that 91% of Nordic tax and finance leaders consider managed services essential due to a deepening technology talent shortage across the region. Specialist SAP data partners are no longer a luxury; they are filling critical skills gaps that internal teams cannot close alone.
Archiving as Migration Preparation
A common objection during S/4HANA planning is, “We will think about archiving after we have migrated.” This mindset should be flipped.
Archiving before migration actively reduces the volume of data that needs to be moved, which fundamentally shortens the migration project itself. It is an investment of time now that significantly reduces time, technical complexity, and cost later.
Post-migration archiving discipline is equally critical. Organisations that move to S/4HANA without establishing an ongoing archiving strategy will quickly rebuild the same bloated data footprint within a few years, entirely defeating the purpose of moving to a lean, modern system.
Secure Your Data Foundation Today
The Nordic enterprises moving confidently toward S/4HANA, driven by a culture that ranks Sweden, Denmark, and Finland in the global top 10 for innovation, are the ones treating data archiving as a strategic first step, not an administrative afterthought.
They are not just managing a technology deadline; they are building a leaner, more governed, and future-ready data foundation that will serve them well beyond go-live.
Whether you are planning your S/4HANA journey in Sweden, Denmark, Finland, or elsewhere across the Nordics, the data foundation you build before migrating will dictate the success of everything that follows.
GlueData specialises in SAP Data Archiving, S/4HANAData Migration, and Master Data Management. We are dedicated to helping Nordic enterprises build the data foundation their digital transformation deserves.
