How long does an S/4HANA migration take?

It depends on scope, data volume and approach. A straightforward brownfield conversion can take several months, while greenfield programs with multiple entities usually take longer. We give a phased estimate after the readiness assessment.

What is RISE with SAP?

RISE with SAP is SAP's subscription offering that bundles S/4HANA Cloud, private edition with infrastructure and services. We can help you evaluate it and handle the migration and functional work, working alongside SAP and your chosen hyperscaler.

What happens to our custom ABAP code?

We analyze usage first; unused code is often retired. Remaining objects are remediated for S/4HANA compatibility, and important extensions can be rebuilt using released APIs or on SAP BTP.

How do you reduce downtime risk?

Through repeated mock cutovers, measured load timings, and a detailed cutover plan with clear go/no-go checkpoints, so production day follows a rehearsed script.

Do you support us after go-live?

Yes. Every migration includes a hypercare period, and we can continue with ongoing application management support.

Overview

Why S/4HANA Migration with VN Softverg

SAP's mainstream maintenance for ECC 6.0 ends in 2027, which makes S/4HANA a question of when, not if. The real decision is how: a fresh start, a technical conversion, or something in between. We help you choose the path that fits your processes, data and budget, then deliver it step by step.

We run readiness checks and custom code analysis, simplify and remediate ABAP, cleanse and migrate master and transactional data with the S/4HANA Migration Cockpit, and rehearse cutover until the timings are predictable. Business Partner conversion, new asset accounting and the Universal Journal are all planned for early, not discovered late.

Whether you are moving on-premise, to a hyperscaler like AWS or Azure, or through RISE with SAP, we keep the focus on outcomes: faster closes, real-time reporting, and a cleaner core that is easier to keep current.

Capabilities

Everything you need, under one roof

From strategy to day-two support — the full scope of our s/4hana migration work.

Readiness Assessment & Roadmap

We use SAP Readiness Check, the simplification item catalog and custom code analysis to size the effort and recommend a migration approach with a phased roadmap.

Brownfield System Conversion

Technical conversion of your ECC system with SUM and DMO, preserving history and configuration while moving to the HANA database and the S/4HANA data model.

Post-conversion reconciliation reports

Greenfield Implementation

A fresh S/4HANA build using SAP Activate and Fit-to-Standard workshops, so you adopt best-practice processes and leave years of customization behind.

Selective Data Transition (Bluefield)

Move selected company codes, years or processes into a new S/4HANA shell for a blend of history and redesign, ideal for carve-outs or consolidations.

Custom Code Remediation

We identify unused objects, fix incompatible code, and refactor critical extensions toward released APIs, cutting the custom code you carry into S/4HANA.
