SAP S/4HANA Cloud Consulting & Migration Services
RISE with SAP · S/4HANA Public + Private + on-prem · Brownfield · Greenfield · Bluefield · AWS · Azure · 30%+ TCO cut
SAP ECC 6.0 leaves mainstream maintenance on 31 December 2027 and extended maintenance two years later — which means every enterprise still running ECC is on a clock, and the calendar will not stop just because the project plan does. SCM Software Lab is a specialised SAP S/4HANA Cloud consulting and ECC migration services firm, focused on getting customers off ECC and on to an S/4HANA estate they can actually run for the next decade.
Three migration paths, one decision. Brownfield converts the ECC system in place, keeping configuration, custom code and history; greenfield re-implements S/4HANA cleanly against best-practice processes; bluefield (selective data transition) takes the parts that work, leaves the parts that do not, and is the right answer for groups merging multiple ECC instances. We help you make that call on evidence, not on a vendor preference.
Cloud is not the same as on-prem S/4HANA. S/4HANA Cloud Public Edition is a fit-to-standard SaaS with quarterly innovation. S/4HANA Cloud Private Edition is a single-tenant managed cloud that carries forward bespoke ECC logic. On-prem S/4HANA still exists for customers with sovereignty constraints. We choose the right edition before we touch SUM, DMO or the cutover plan — because the edition decision drives licence, deployment and operating model for the next five years.
What this page covers. Cloud-first S/4HANA strategy and the ECC migration mechanics behind it — not generic SAP advisory (see SAP consulting companies) and not general implementation methodology (see SAP implementation companies). For the detailed migration playbook read our ECC to S/4HANA migration guide, and for budgeting work through the S/4HANA implementation cost guide. Returning customers can step back up to SAP ERP consulting.
Cloud Migrations, Delivered Globally
S/4HANA Cloud migrations delivered across India, the US, the UK and the Middle East.
Six Services That Move You From ECC to S/4HANA Cloud
A migration is not one project — it is six. Each of these is a discrete engagement with its own deliverable, its own gate and its own fixed-scope proposal.
Migration Path Assessment
Five business days to benchmark the ECC system — release, database size, modification index, business-process health, custom-code footprint, integration map — and produce a defensible recommendation between brownfield, greenfield and bluefield with a fixed-scope proposal for the next phase.
Brownfield (System Conversion)
In-place ECC to S/4HANA conversion using SUM with the Database Migration Option. Configuration, custom code and history move forward; the Customer Vendor Integration runs against the new business partner model; the simplification list is closed item by item; cutover is a planned weekend, not a re-implementation.
Greenfield (New Implementation)
Clean S/4HANA build against SAP best-practice processes, using SAP Activate sprints, ready-to-run business content and BTP side-car for what makes you different. The right path when ECC is unrecoverable, when the business has changed shape or when finance wants the central finance reset.
Bluefield (Selective Data Transition)
A hybrid path delivered with SNP CrystalBridge or SAP-led SDT. We keep the configuration that earns its keep, reset the parts that do not, and carry only the open documents and the history you actually need. The pragmatic answer for groups consolidating two, five or ten ECC instances into one S/4HANA estate.
RISE with SAP Onboarding
Commercial structuring of full-user-equivalent licences, tenant provisioning, hyperscaler landing zone, network and identity integration, and the formal hand-off to SAP-managed operations. We act as the customer-side counterpart so RISE delivery teams see one disciplined buyer, not five.
Cloud Operations & FinOps
Post-go-live managed services on AWS, Azure, GCP or HEC — basis, hyperscaler cost control, licence true-up against actual consumption, quarterly innovation adoption and SAP Note management — so the cloud TCO commitment made on day one still holds on day one thousand.
Three migration paths. One decision framework.
Brownfield is the path for ECC customers whose business model has not changed. If your processes are healthy, your custom code is real and your history must survive the move, system conversion is the right answer. SUM with the Database Migration Option moves database, application stack and ABAP in a single technical exercise — configuration is preserved, the simplification list is the only mandatory change, and the financial close keeps its years of comparison.
Greenfield is the path when ECC is no longer the system the business actually runs in. Workarounds outnumber transactions, the modification index is in the tens of thousands, central finance has been promised for years, or a recent merger has fragmented the chart of accounts. Greenfield uses SAP Activate, ready-to-run content and a fit-to-standard mindset — with BTP side-car for the genuinely differentiated processes the business will not give up.
Bluefield is the path for groups consolidating multiple ECC instances into one S/4HANA estate. Five plant codes become one, three chart-of-accounts collapse to one global plan, and only the open documents and the relevant history carry over. SNP CrystalBridge or the SAP Selective Data Transition engine extract precisely the rows that earn their keep, transform them for the new model and load them into a clean S/4HANA target. The result is faster than greenfield, smaller-scope than brownfield, and far less risky than either at scale.
ECC vs S/4HANA On-Prem vs S/4HANA Cloud
Three operating models, ten attributes that actually move the needle. The right destination depends on which column you can defend to the board in three years, not on which one is easiest to demo today.
SAP ECC 6.0
Runs on any certified database — Oracle, DB2, SQL Server — HANA optional from 2015.
SAP GUI is the primary UI; Web Dynpro for a few flows; Fiori only with a deliberate UX project.
Perpetual licences, on-prem capex; maintenance ends 31 December 2027 (extended to 2030).
Customisation is unlimited — modifications, user exits, classical reports, repaired SAP code.
Statutory updates ship via legal change notes through 2027; after that the customer is on their own.
High three-to-five-year TCO once basis, database, hardware refresh and external upgrades are counted.
Innovation cadence is enhancement packs — roughly one feature pack every eighteen months.
Vendor lock-in is moderate — SAP for the suite, but database and basis are negotiable.
Customer-paced upgrades, typically every three to five years; many landscapes are two EHPs behind.
Exit cost is the price of the next migration project — capital write-off plus the move itself.

S/4HANA On-Prem
HANA only — the database choice is gone, but in-memory columnar performance is the trade.
Fiori is the default UX with role-based launchpad; SAP GUI remains for power-user transactions.
Perpetual licences on customer-owned infrastructure; full control of the basis layer.
Customisation still unlimited — though the clean-core discipline is strongly recommended.
Statutory updates ship via support packages and SAP Notes, applied by your basis team.
TCO sits between ECC and Cloud Private Edition — capex up front, opex on the basis team.
Annual feature pack stack release — one major upgrade window per year if you adopt them.
SAP plus HANA — tighter coupling than ECC, but your team still operates the platform.
Yearly cadence is the SAP recommendation; deferring more than two years adds compounding upgrade debt.
Lower than ECC — you own the licences and the data; moving to cloud is a deployment swap.
S/4HANA Cloud (Public + Private)
Database: HANA only, but the database is managed by SAP or by the hyperscaler — you stop running it.
UI: Fiori everywhere; Public Edition removes SAP GUI for end users; Joule conversational AI ships in the launchpad.
Licence model: Subscription per full-user-equivalent inside RISE with SAP — opex, not capex; flex up and down.
Customisation: Public Edition is fit-to-standard with extensions on BTP; Private Edition preserves bespoke ECC code.
Statutory: Quarterly compliance releases pushed by SAP — India GST, UK Making Tax Digital, EU VAT updates land automatically.
Total cost: 30%+ TCO reduction across three years once licence, infrastructure and basis ops are aggregated against the previous ECC run.
Innovation: Quarterly releases for Public Edition, half-yearly for Private — new capabilities arrive without a project.
Vendor lock-in: Highest of the three — SAP for the suite, SAP or hyperscaler for the platform; the trade for the operating-cost saving.
Upgrade frequency: Continuous — SAP applies updates on a published schedule; your team validates business processes, not the technical move.
Exit cost: Highest of the three — data export is possible but the operating model is what you actually leave behind.
Cloud Migration Capabilities
Twelve technical capabilities that decide whether an S/4HANA migration finishes on the weekend it was supposed to, on the budget it was scoped to, and at the operating cost the business case was sold on.
ECC Mainstream Support Roadmap
Where your release sits against the 2027 mainstream and 2030 extended maintenance dates — and what the realistic move-by date is for your specific landscape, not the SAP slide.
DMO — Database Migration Option
Database migration and upgrade in a single SUM run — Oracle, DB2, SQL Server moved to HANA without a separate heterogeneous system copy. Downtime-optimised DMO compresses large landscapes under twelve hours.
SUM-Driven Conversion
Software Update Manager run-time orchestrates the technical conversion — uptime phases, downtime phases, business partner conversion, customer-vendor integration, post-conversion activities — with re-startable steps and audit trails.
Custom Code Adaptation
Readiness Check 2.0, ATC with S/4HANA variant, Code Inspector and clean-core retrofit — deprecated tables, removed transactions and changed APIs identified up front and refactored before the cutover, not after.
Fiori UX Migration
Role-based launchpad rollout, Fiori app catalogue mapping to ECC transactions, custom Fiori for the gaps and SAP GUI for HTML where the long-tail transactions still belong — user adoption planned, not assumed.
BTP Side-Car Architecture
SAP Business Technology Platform — CAP, RAP and Integration Suite — for genuinely differentiated extensions, so the S/4HANA core stays clean and quarterly upgrades stop being a project of their own.
Cloud Native Integration
SAP Integration Suite, Cloud Connector, Event Mesh and Open Connectors — replacing ageing PO and PI estates with a cloud-first integration layer that survives the move to RISE without re-architecting.
Data Volume Management
SAP DVM, ILM, ADK archiving and decommissioned-system replacement strategies — cutting database size before the migration so the HANA footprint and the cloud bill both shrink at go-live.
Licence Optimisation
SAP user measurement, full-user-equivalent conversion and indirect-access digital-document review — the same engagement that frees the licence budget needed to pay for the cloud subscription.
Test Automation
SAP Cloud ALM test orchestration, Tricentis Tosca for end-to-end automation and Solution Manager for unit-level regression — running the same scenarios on ECC and on S/4HANA so the cutover compares output, not opinion.
Cutover War Room
A weekend control tower — functional leads, basis, security, integration, infra, telco — with a minute-level runbook, go/no-go gates and a rollback script that exists in writing before Friday evening.
Cloud FinOps Continuity
Hyperscaler tagging, reserved-instance management, S/4HANA Cloud consumption metering and quarterly licence true-up — so the cloud TCO commitment made in the business case still holds in year three.
Why S/4HANA Cloud Is a Board Conversation
Nine outcomes a CFO, COO or CIO can each take into their own committee — the same migration delivers a different proof to each audience.
ECC sunset risk addressed
The 2027 mainstream and 2030 extended maintenance dates stop being a tail risk on the audit committee’s register and start being a closed item.
Up to 30% TCO reduction
Aggregated three-year savings across licence subscription, infrastructure consolidation, basis automation and statutory-update labour — benchmarked against the previous ECC run.
Real-time analytics with HANA
In-memory columnar HANA replaces overnight batch — embedded analytics, CDS views and live operational reporting against the transactional record, no separate BW project required.
Quarterly innovation in cloud
Public Edition ships every quarter, Private Edition twice a year — new features arrive on a schedule, not as a capital-funded upgrade programme every three years.
Reduced custom code
The clean-core discipline cuts modifications by sixty to eighty percent on a typical brownfield, lowering future upgrade cost and shortening every regression cycle that follows.
Vendor-managed infrastructure
Inside RISE with SAP, SAP owns the basis, hyperscaler and OS layers — your team is freed for business work instead of patching kernels at midnight.
Continuous compliance
India GST, UK MTD, EU VAT, Saudi e-invoicing and statutory updates from every other jurisdiction land through the cloud release stream — not through a separate localisation project.
Pay-as-you-grow
Full-user-equivalent subscription scales with the business — a seasonal retailer flexes up for the festive quarter; a divestiture flexes down without writing off perpetual licences.
Side-car BTP innovation
The genuinely differentiated processes that justify the bespoke logic move to SAP BTP — CAP, RAP, Integration Suite — sitting beside S/4HANA, not inside it.
The Migration Flow — Assess, Plan, Convert, Optimise
Every successful S/4HANA Cloud migration we have delivered — from a four-hundred-user single-country ECC system to a multi-country group consolidation — followed the same four-phase flow. The artifacts change, the cadence changes, the war-room composition changes; the discipline does not.
1. Assess
Five business days end-to-end. SAP Readiness Check 2.0, custom-code scan with ATC, business-process discovery interviews, integration inventory and hyperscaler architecture options. The deliverable is a defensible recommendation between brownfield, greenfield and bluefield, plus a fixed-scope proposal for the next phase. No upfront fee.
2. Plan
Detailed planning sprint — landing zone on AWS, Azure, GCP or HEC; tenant model for RISE; integration target architecture with Integration Suite; data-migration strategy with object-level mapping; functional fit-gap with business owners; cutover plan with minute-level runbook; rollback plan that actually exists in writing before convert begins.
3. Convert
The technical migration — SUM with DMO for brownfield, SAP Activate sprints for greenfield, SDT or CrystalBridge for bluefield. Sandbox, development, quality and production conversions executed in disciplined succession; business validation against parallel ECC at each gate; data reconciliation signed off line by line; cutover weekend run from a unified control tower.
4. Optimise
Twelve weeks of hypercare run twenty-four-seven from the war room, followed by managed operations — cloud FinOps, quarterly innovation adoption, licence true-up, Fiori catalogue expansion, BTP side-car build-out. The cloud TCO commitment made in the business case is the metric we manage to in year one, year two and year three.

Fixed-scope migration proposals
Migration By Sector
The migration path that wins varies by sector — manufacturing has plant codes, banking has regulators, retail has POS estates, pharma has validation, logistics has connected fleets. Eight sectors, eight specific cloud-migration considerations.
Manufacturing
Plant-code consolidation and EWM integration drive a bluefield path — ten ECC instances become one S/4HANA estate with embedded production planning and Digital Manufacturing on BTP.
Banking
Regulatory data residency and GRC continuity make Private Edition on a regional hyperscaler the safe answer — treasury and CML migrated with central finance reset, IFRS 9 retained.
Retail
Festive peak load and POS integration force a fit-to-standard greenfield with omnichannel orchestration on BTP — the move is timed for the off-season, not against Black Friday.
Pharma
GxP validation, computer-system validation and serialisation make brownfield the path of least re-validation — existing IQ/OQ/PQ packs are extended rather than rewritten from zero.
Logistics
Connected fleet, telematics and yard management push integration to the front of the plan — SAP TM and SAP EWM modernised on cloud with Integration Suite replacing legacy PO.
Utilities
SAP IS-U meter-to-cash sits on top of S/4HANA Utilities — brownfield with selective archiving cuts the historic device-management footprint and unlocks the HANA performance dividend.
Telco
BRIM convergent charging and billing on S/4HANA replace ageing CC and CI estates — subscription, prepay and B2B revenue models harmonised inside one billable record.
Public Sector
Sovereign cloud, citizen data residency and audit trail set the bar — Private Edition on a sovereign hyperscaler region with extended retention via SAP ILM as the standard pattern.

Cloud is not a destination. It is a discipline.
We move you there once, then we stay to keep you fluent. Quarterly innovation, licence true-up, FinOps tagging, custom-code retro-fit and BTP side-car build-out — the work that turns an S/4HANA Cloud go-live into a three-year TCO win does not happen on its own. It is the operating routine of an estate that earns its subscription.
Why SCM Software Lab for S/4HANA Cloud Migration
Nine reasons buyers shortlist us when the migration is real, not theoretical. None of them are about brand recognition; all of them are about specific delivery muscle.
ECC Migration Specialists Since RISE Launch
Migration is our line of business, not a side practice. We have moved ECC customers off mainstream maintenance since the day RISE with SAP launched — the methodology, the runbook and the failure modes are documented from real cutovers.
Brownfield + Greenfield + Bluefield Experience
We have shipped all three paths, on the same week, for different customers. That is the only way to give honest advice between them — a firm that has only ever sold one path will recommend it every time.
Multi-Cloud — AWS, Azure, GCP, HEC
SAP-certified deployment patterns on all four targets. We architect for the cloud the customer already has a commitment to, not the one our sales team has a quota with.
SAP-Certified Migration Consultants
S/4HANA conversion, RISE with SAP architecture, BTP, Fiori and HANA certifications across the migration team — not just the technical lead on the proposal slide.
DMO + SUM Mastery
Downtime-optimised DMO, near-zero downtime maintenance, parallel exports and pre-converted minimal databases — the techniques that cut a fifty-hour cutover to under twelve.
Licence Optimisation In Scope
SAP user measurement, full-user-equivalent conversion and indirect-access digital-document review are inside the migration scope — the saving usually pays for the technical project.
Cloud FinOps Continuity
We do not hand the FinOps problem back to the customer at go-live. Tagging, reserved-instance management and licence true-up run as a managed service that protects the TCO commitment.
Fixed-Scope Migration Proposals
The proposal that comes out of the five-day assessment is fixed scope, fixed timeline and fixed price — not a time-and-materials envelope with a ceiling and a smiley face.
24x7 Cutover Hypercare
Twelve weeks of round-the-clock hypercare from the war room, with functional, basis, security and integration leads on standby — the difference between a clean go-live and a six-month aftermath.
S/4HANA Migration FAQs
Eight questions buyers ask most when their ECC system is on the clock and the path forward is still a slide.
When does SAP ECC mainstream support end and what are my options?►
SAP ECC 6.0 mainstream maintenance ends 31 December 2027, with extended maintenance available at a premium until 31 December 2030. After that, ECC moves to customer-specific maintenance with no new patches or statutory updates. Practical options are: convert to S/4HANA on-premise or private cloud, subscribe to RISE with SAP for S/4HANA Cloud Private Edition, adopt S/4HANA Cloud Public Edition for a fit-to-standard re-implementation, or run extended maintenance while planning the move.
Should I pick brownfield, greenfield or bluefield migration?►
Brownfield (system conversion) is the right choice if your ECC processes are healthy, custom code is needed and history must stay intact — it carries the whole landscape forward in place. Greenfield is right when ECC is heavily customised, processes are broken or the business has changed shape and you want SAP best practice with a clean slate. Bluefield (selective data transition) sits between the two — it keeps the parts that work, resets the parts that do not, and is the most common choice for groups consolidating multiple ECC instances.
What is RISE with SAP and do I need it?►
RISE with SAP is a single subscription that bundles S/4HANA Cloud Private Edition, the underlying hyperscaler infrastructure, technical managed services and embedded tools like SAP Business Technology Platform, Signavio and LeanIX. You need it if you want SAP as the single accountable party for the cloud run-state, or if you want a consumption-priced commercial model instead of perpetual licences. You do not need it if you prefer to run S/4HANA on your own hyperscaler contract and manage the basis layer separately.
What is the difference between S/4HANA Cloud Public Edition and Private Edition?►
Public Edition is a true multi-tenant SaaS — quarterly innovation releases, fit-to-standard processes, no modifications, side-by-side extensions only on BTP, fastest time-to-value. Private Edition is single-tenant managed cloud — full customisation depth, custom code allowed, annual release adoption, and a one-to-one mapping for ECC customers who carry years of bespoke logic. Public is for clean-core businesses; Private is for ECC customers who want cloud without losing their differentiated processes.
How much downtime should I plan for the ECC to S/4HANA cutover?►
A standard brownfield cutover for a medium ECC system using SUM with DMO runs roughly forty to seventy-two hours of business downtime, planned across a weekend. With DMO downtime-optimised techniques — near-zero downtime maintenance, parallel exports and pre-converted minimal databases — large landscapes have been compressed to under twelve hours. Greenfield cutovers are usually shorter at the cutover itself but require a longer pre-cutover data migration window.
Will my custom ABAP code work in S/4HANA?►
Most ABAP compiles in S/4HANA, but it does not all run correctly. The S/4HANA simplification list deprecates classical tables — MARC, MBEW, KONV, BSEG enhancements — and removes transactions like MD04 and VA01 in their old form. Our custom code adaptation runs the SAP Readiness Check, the ABAP Test Cockpit with S/4HANA variant and the Code Inspector, then refactors the flagged objects, replaces deprecated APIs with the released ones and validates against Fiori where the UI changed.
Can I migrate to S/4HANA Cloud on AWS or Azure or do I need SAP HEC?►
Yes. S/4HANA is SAP-certified to run on AWS, Microsoft Azure and Google Cloud Platform — all three hyperscalers offer SAP-validated virtual machine families and HANA-certified storage. SAP HEC (now branded as SAP-managed infrastructure inside RISE with SAP) is the SAP-operated option. The right answer depends on existing cloud commitments, network latency to surrounding workloads, regional data-residency requirements and whether you want SAP or your own team owning the basis layer.
What is the realistic cost of an S/4HANA migration?►
For a mid-market ECC customer of three hundred to one thousand users, a brownfield system conversion typically lands between 300,000 and 900,000 USD in services, with the RISE with SAP subscription adding 100,000 to 400,000 USD per year depending on full-user-equivalents. Greenfield re-implementations sit higher at 600,000 to 1.8 million USD in services because they include process design, data migration and change management. Bluefield projects fall between the two. Most of our customers achieve a thirty percent or greater TCO reduction within three years once licence optimisation, infrastructure consolidation and operations efficiency are counted. See the S/4HANA implementation cost guide for the detailed model.
