Migrating from a Non-SAP ERP to SAP S/4HANA Cloud Public Edition

For organizations on Microsoft Dynamics, Exact, AFAS, Oracle NetSuite, Infor, and other non-SAP platforms — how the move to SAP S/4HANA Cloud Public Edition works, and why starting without legacy SAP can be an advantage

Migration Paths NON SAP ERP systems SAP S/4HANA Cloud Public Edition

Migrating from a non-SAP ERP to SAP S/4HANA Cloud Public Edition is, in structural terms, closer to a new implementation than to a system conversion. There is no existing SAP database to convert and no accumulated SAP customization to carry forward, so the solution is built on SAP's Industry Best Practices and adapted to the organization, rather than reshaped from a legacy SAP landscape.

Organizations arrive from a wide range of platforms — Microsoft Dynamics 365 Business Central / NAV, Exact Globe / Synergy, AFAS Profit, Oracle NetSuite, Infor LN, Epicor ERP, Visma AccountView, ECI Ridder iQ, Odoo, or Sage 100, among others. The source system does not determine the method: in every case the migration is assessed the same way, by measuring current processes and data against the standardized target rather than lifting them across unchanged.

What the move looks like from your current ERP

Each platform leaves its users in a slightly different position. Organizations on Dutch mid-market systems such as Exact, AFAS Profit, Visma AccountView, or ECI Ridder iQ often reach their limits once operations become multi-entity, international, or manufacturing-intensive, where standardized processes and native multi-company, multi-currency support matter. Users of international mid-market platforms such as Microsoft Dynamics 365 Business Central / NAV, Infor LN, Epicor ERP, Oracle NetSuite, or Sage 100 typically carry a heavily customized, integration-dependent landscape that SAP's built-in best practices can reduce. And organizations on a flexible open-source ERP such as Odoo gain enterprise-grade governance and a continuously updated platform.

The approach is consistent across all of them. A fit-to-standard analysis maps required functionality against SAP Best Practices and the scope of SAP S/4HANA Cloud Public Edition — more than 850 standard functional scope items — so end-to-end processes such as Order-to-Cash, Source-to-Pay, Plan-to-Produce, and Record-to-Report have a strong chance of a direct fit. Data is migrated selectively rather than wholesale, and requirements outside standard scope are handled through SAP Business Technology Platform extensions rather than modifications to the core, which keeps a Clean Core realistic from the start.

Why starting without legacy SAP is an advantage

Because there is no legacy SAP database to convert and no years of SAP customization to reconcile, a non-SAP organization can start directly on current best practices, much like a GreenField implementation. The effort shifts from technical conversion to process alignment, data preparation, and change management, resulting in a current, standardized system from day one rather than a modernized copy of an older one. Scheer IDS supports these migrations from a Discovery Assessment through implementation with SAP Activate.

Non-SAP — Frequently Asked Questions

Is migrating from a non-SAP ERP to SAP harder than moving between SAP systems?

No — in most cases it is cleaner. With no existing SAP landscape to reconcile and no years of SAP customization to carry forward, a non-SAP organization starts directly on SAP's Industry Best Practices, much like a GreenField implementation, rather than untangling a legacy SAP system first.

Which non-SAP systems can move to SAP S/4HANA Cloud Public Edition?

A wide range, including Microsoft Dynamics 365 Business Central / NAV, Exact Globe / Synergy, AFAS Profit, Oracle NetSuite, Infor LN, Epicor ERP, Visma AccountView, ECI Ridder iQ, Odoo, and Sage 100, among others. The approach is the same regardless of the source system: assess current processes against the SAP standard, then configure and migrate what the organization genuinely needs.

What do organizations gain by moving from a mid-market ERP such as Exact or AFAS Profit?

Scalable, standardized processes with native multi-company and multi-currency support, and the industry depth that mid-market platforms tend to reach their limits on once operations span multiple entities, countries, or complex manufacturing.

What happens to the customizations in a system like Microsoft Dynamics?

A fit-to-standard analysis maps requirements to SAP's pre-built scope items, so much of what was custom in the previous system is available as standard functionality. Genuinely unique requirements are handled through SAP Business Technology Platform extensions rather than custom code in the core.

How is the migration scoped?

It typically starts with a Discovery Assessment that sets business goals and processes against the SAP S/4HANA Cloud Public Edition scope — more than 850 standard functional scope items. Data is migrated selectively, so the organization brings the master data and history it actually needs rather than copying the old system's structures into a clean platform.

Will existing processes fit SAP's standard, or is heavy custom work needed?

With more than 850 standard scope items covering end-to-end processes such as Order-to-Cash, Source-to-Pay, Plan-to-Produce, and Record-to-Report, most organizations achieve a high degree of direct fit. Fit-to-standard workshops confirm where processes match the standard and where a genuine gap needs an SAP Business Technology Platform extension.

What is Clean Core, and why does it matter coming from a non-SAP system?

Clean Core means keeping the SAP core close to the standard, with extensions built outside it on SAP Business Technology Platform. Coming from a non-SAP system is an advantage here: with no legacy SAP customization layer to carry forward, a Clean Core is realistic from day one, which keeps upgrades smooth and maintenance costs low.

How long does a non-SAP migration take?

Because the solution is built on Industry Best Practices rather than converted from a legacy SAP system, timelines are typically measured in months and depend on scope, number of entities, data complexity, and the extensions required. SAP Activate structures the project through the Prepare, Explore, Realize, Deploy, and Run phases.
