What 2027 Means for Training, Adoption, and Change Risk
SAP’s ECC end-of-maintenance in 2027 is approaching quickly. For many organisations, this is no longer a distant milestone. If no action has already been taken it is an active programme risk.
However, the challenge is not only technical. Migration to SAP S/4HANA introduces changes to processes, roles, and behaviours.
What does the 2027 deadline mean for training, adoption, and change risk?
SAP ECC End of Maintenance 2027: What Is Changing?
SAP has confirmed that mainstream maintenance for SAP ECC will end in 2027. Extended maintenance options are available, although they come at a higher cost.
As a result, organisations must decide whether to migrate, transform, or extend legacy systems temporarily. However, moving to SAP S/4HANA is not a simple upgrade. It is a shift in operating model, albeit one increasing numbers of SAP ECC sites have successfully made.
S/4HANA introduces Fiori-based user experiences, simplified data models, and standardised processes aligned to clean core principles. Consequently, user interaction with the system changes significantly.
Why S/4HANA Migration Readiness Is More Than Technology
Many organisations initially focus on technical readiness. This includes system conversion, data migration, and infrastructure planning. While important, this is only one part of the picture.
Research from McKinsey & Company shows that transformation programmes often fail due to adoption challenges rather than technology issues.
Similarly, Deloitte highlights that user readiness is a key driver of ERP programme success.
Therefore, S/4HANA migration readiness must include people, processes, and behaviours. Without this, organisations risk delayed adoption and reduced return on investment. This can be seen as a technical shift, but the organisation becomes out of step.
The Training Gap in S/4HANA Programmes
Traditional SAP ECC training focused on transactions and navigation. Users followed structured steps within a familiar interface. However, S/4HANA introduces a different experience.
Fiori applications are role-based and process-driven. Users must understand end-to-end workflows rather than isolated transactions. This creates a training gap and requires a new approach to training.
If training remains transaction-focused, or relies on generic one-size-fits-all materials users are very likely to struggle to adapt. As a result, confidence decreases, and errors increase post go-live and ROI will nosedive.
iTrain’s deep experience across S/4HANA programmes designing, developing and delivering company-specific S/4 enablement programmes has consistently shown that early engagement in role-based learning improves adoption outcomes.
Clean Core and Its Impact on Users
The move to S/4HANA is closely linked to the clean core principle. This approach limits customisation and promotes standard processes.
While this improves system stability, it changes how users work.
Previously, many organisations adapted SAP ECC to fit existing processes. In contrast, S/4HANA encourages organisations to adopt standard workflows.
This requires behavioural change. A path many other ECC sites have now successfully completed.
Users must adjust to new ways of working rather than relying on customised transactions.
According to PwC, clean core strategies improve long-term agility. However, they also require strong change management to succeed.
Lessons from S/4HANA Transformation Programmes
Experience from real programmes highlights consistent risks. For example, iTrain’s work across large ERP transformations shows that adoption issues often emerge after go-live. These issues are rarely technical. Instead, they relate to user understanding, confidence, and process alignment.
Across these programmes, organisations that aligned training, testing, and change management achieved stronger outcomes.
In contrast, programmes with fragmented approaches often experienced extended hypercare periods and lower than expected programme ROI..
Why Change Management Is Critical for 2027
The 2027 deadline creates pressure. However, rushing migration without addressing change risk can lead to long-term issues. Change management provides structure during this transition.
It ensures that users understand why changes are happening. It also supports communication, engagement, and reinforcement. Moreover, it aligns training with business objectives.
iTrain’s approach integrates change management with learning and testing. This helps organisations manage both technical and behavioural risks. Programmes are successful at both technical and organisational levels.
Embedding Training into Migration Strategy
Training should not be treated as a standalone activity. Instead, it must be embedded within the migration programme.
Firstly, training should begin early. iTrain, or your training partner, are a key component of the programme. Users need exposure to new processes in a more sophisticated, structured engagement than simply a run-through before go-live.
Secondly, learning should be role-based and scenario-driven. This ensures relevance to daily tasks. In addition, reinforcement is essential. Post go-live training supports long-term adoption, maintains functional awareness and as with all systems enables performance tuning.
This approach reduces risk and improves confidence. It also ensures that users can operate effectively from day one.
What Organisations Should Do Now
With 2027 approaching, organisations should act decisively.
Firstly, assess current readiness for S/4HANA migration. This should include both technical and user readiness.
Secondly, identify gaps in training and change management. These areas often represent the highest risk.
Finally, align training, testing, and change strategies. Integration is key to successful adoption. Organisations that take this approach are better positioned to meet the deadline without disruption.
