Service
Full-Service S/4HANA Migrations
Whether greenfield or brownfield, we guide you through low-risk, high-impact migrations. We ensure continuity, compliance, and future-readiness.
Overview
S/4HANA migration is not a re-implementation, but it's not a Basis upgrade either. It's a decision program first — what to bring forward, what to leave behind, which custom code survives, which finance configurations get re-thought, where simplification lives — and a technical program second.
deBCor delivers the full lifecycle: brownfield (in-place conversion of your ECC system), greenfield (fresh S/4HANA build with deliberate data carry-forward), and selective data transition (the middle path that combines re-implementation with brownfield data). We help you choose the right path before we deliver it.
Migrations include cutover planning, parallel runs, custom code remediation, finance simplification (New GL, document split, COPA, FI/CO integration), Fiori activation, and post-cutover stabilization. Senior architects on the lead at every phase.
The Challenge
SAP ECC Support Is Ending in 2027
Delaying your migration increases operational risk, limits innovation, and inflates long-term costs. But a poorly executed migration can be even worse. It can lead to instability, downtime, and resistance across your organization.
You only get one shot at doing this right.
How we deliver
Our engagement model.
- 01
Step 1 — Decide the path
Greenfield, brownfield, or selective transition. We map your ECC estate against the future you're actually trying to build — not against a methodology — and recommend the route with the clearest payback. Four to six weeks. No deck-ware.
- 02
Step 2 — Blueprint to cutover weekend
Detailed migration plan, data-prep program (often using our AI Phase 0 diagnostic), custom-code remediation, finance simplification design. Built jointly with your team so the plan isn't ours — it's yours, accelerated.
- 03
Step 3 — Move, validate, repeat
SUM/DMO or Migration Cockpit. Parallel runs. Finance reconciliation. Fiori activation. Real users firing real transactions weeks before cutover, so the surprises surface in sandbox — not in hypercare.
- 04
Step 4 — Cut over, then stay
Cutover-weekend command center, hypercare through the first weeks, and a documented handoff into Managed Services if you want continuity. We don't disappear at go-live. Most clients keep us on; some don't. Both are fine.
Frequently asked questions
Most projects take 6 to 12 months, depending on system complexity and business readiness.
Yes. We evaluate your existing landscape and recommend the best-fit approach based on risk, cost, and future flexibility.
Absolutely. We complement your internal team, fill any skill gaps, and ensure your staff is supported and empowered throughout the project.
Inventoried, classified (keep / refactor / retire / re-architect on BTP), and remediated as part of the migration. SAP's standard tools (Custom Code Migration app, ATC) plus deBCor's own analytics.

Client experience
“DEBCOR's white-glove approach to consulting isn't just a tagline — it's the reality of their service. They've been our trusted partner for many years because of the integrity of their approach. At our request, they cleaned up our technical debt and prepared us for S/4HANA. The migration only took four months — we were down for maybe a weekend, then back to business with no loss in revenue.”
