Free S/4HANA Readiness Assessment

Why Move Now

The clock is ticking on SAP ECC

SAP ends mainstream maintenance for ECC 6.0 in 2027, with costly extended maintenance only until 2030. Every quarter you wait, migration talent gets scarcer and timelines get riskier. But S/4HANA is far more than a forced upgrade:

Real-time everything: the in-memory HANA database eliminates batch jobs and overnight reporting waits.
Simplified data model: the Universal Journal merges FI and CO into a single source of financial truth.
Fiori user experience: role-based, mobile-ready apps replace decades-old transaction screens.
Embedded intelligence: built-in analytics, machine learning and the Joule AI assistant.
Lower TCO: smaller data footprint, fewer add-ons, simplified landscape operations.

Migration Paths

Three roads to S/4HANA. One right answer for you.

We recommend from evidence — a scored assessment of your processes, custom code and data — not from what's easiest to sell.

Greenfield

New Implementation

Start fresh with a clean core and SAP Best Practices. Ideal when legacy processes are outdated or the current system is customized beyond repair.

Re-engineered, standardized processes
Clean master data from day one
Selective historical data migration
Fastest route to innovation adoption

Brownfield

System Conversion

Convert your existing ECC system in place using SUM/DMO. Preserves your processes, configuration and full history with the least business change.

Keeps proven processes & customizations
Full historical data retained
Shorter project, lower change impact
Downtime-optimized DMO execution

Hybrid

Selective Transition

The best of both: carve out what works, redesign what doesn't, and consolidate multiple ERPs into one S/4HANA instance.

Multi-ERP consolidation
Selective data & config transition
Phase-wise business go-lives
Ideal for M&A and carve-outs

Scope of Work

Your migration, step by step

Everything our S/4HANA service covers, in the order it happens.

Assessment

Readiness check, simplification-item analysis, custom code evaluation and business impact mapping — so the plan is built on facts.

Custom Code Remediation

ATC-driven cleanup and HANA optimization of Z-programs. Typically 30–50% of custom code is unused and simply retired.

Data Migration

Cleansing, de-duplication, Migration Cockpit loads, validation and business-signed reconciliation reports.

Finance Conversion

New GL migration, customer/vendor to Business Partner (CVI) and Universal Journal adoption.

Fiori Activation

Launchpad setup, role-based app catalogs and UX adoption for your key business roles.

Testing

Unit, integration, regression and UAT cycles with documented scripts and tracked defect burn-down.

Cutover & Go-Live

Rehearsed cutover plans, minimized downtime windows, go/no-go governance and command-centre support.

Hypercare & AMS

Post-go-live stabilization, user hand-holding and a smooth transition into managed support.

FAQ

S/4HANA migration questions, answered

It depends on how well your current processes serve the business, how much custom code you carry, and your appetite for change. Heavily customized systems with outdated processes favour greenfield; well-run ECC systems with valued history favour brownfield. Our assessment gives you a scored recommendation, not a guess.

With the Database Migration Option (DMO) and downtime-optimized techniques, most mid-size conversions complete within a weekend window (24–48 hours of technical downtime). For very large databases we apply near-zero-downtime approaches to shrink the window further.

We run SAP's custom code analysis against the simplification database to classify every object: still works, needs adjustment, or obsolete. Typically 30–50% of custom code is unused and can be retired — reducing both migration effort and future maintenance cost.

Yes. With selective data transition we can go live by company code, region or business unit. Phased approaches lower risk for multi-national landscapes, though they need temporary interfaces between old and new systems — we design and operate those bridges as part of the project.

Yes — S/4HANA on-premise, S/4HANA Private Cloud (RISE with SAP), and S/4HANA Public Cloud (GROW with SAP). We advise on the right deployment model based on your customization needs, compliance requirements and budget, then deliver the implementation end to end.
