SAP’s 2027 maintenance deadline is driving SAP S/4HANA migrations. The date is technical. The risk that determines ROI is human — and it starts long before go-live.
There’s a date showing up on a lot of roadmaps right now: 2027. That’s when SAP ends mainstream maintenance for ECC (with extended maintenance available until 2030 for organizations that choose to pay for it).
It’s real. It’s one of the key drivers behind SAP S/4HANA migration programmes. And in many organizations, it is still treated primarily as a technical problem with a technical deadline.
That framing is where a significant part of the risk begins.
The 2027 date defines when standard support ends. It does not define when an organization is actually ready to work differently.
These are two different timelines. The system timeline is fixed and visible. The human timeline is slower, less visible, and shaped by trust, habits, capability, and how people adapt to change in practice.
When migration programmes are driven primarily by the technical milestone, a familiar pattern often emerges. The focus naturally concentrates on design, build, configuration, testing, and cutover planning. The people side is sometimes addressed later in the lifecycle, often through training, communications, and go-live readiness activities.
The system goes live. On paper, the programme is complete. But in practice, people are asked to work differently in a system they may not have meaningfully helped shape, within a change journey they were not fully part of from the beginning.
In those cases, the issue is not the technology. It is the gap between system readiness and human readiness.
In most transformation programmes, the earlier the people side is addressed, the lower the cost of change.
Early on, change work is about involvement. Identifying who is affected, understanding how their daily work will change, and shaping the future process with them rather than only designing it for them. At that stage, influence is strong, and resistance is still preventable.
When that work is delayed, the nature of change shifts. It becomes less about design and more about adoption. Less about shaping behavior and more about resolving resistance. At that point, conversations take longer, alignment takes more effort, and the cost of coordination increases.
The investment in change does not disappear when it is delayed. It typically increases.
Early readiness is not primarily about training volume or communication output. It is about asking different questions earlier in the lifecycle.
The 2027 date matters. And in some cases, extended maintenance until 2030 provides additional flexibility for organizations that require it.
But these are still technical milestones. They define system support timelines, not business value realization.
The outcome that ultimately determines ROI runs on a different clock entirely. A human one. And that clock starts the moment people become aware that change is coming — whether or not it is actively managed from the beginning.
If you are planning an SAP S/4HANA migration this year, a useful question is not only when the system will go live, but when people will actually be ready to use it effectively.
Are you treating people readiness as part of the design phase, or as an activity that follows go-live?
Planning an SAP S/4HANA migration? It may be worth aligning system readiness and people readiness from the start, not after cutover.
