The Challenge

SAP ECC End-of-Maintenance Creates an Unavoidable Strategic Decision

SAP has confirmed mainstream maintenance for ECC ends in 2027, with extended support available only under premium contract terms. Organisations that delay their S/4HANA transition face escalating technical debt, security exposure on an unsupported platform, and competitive disadvantage as peers leverage real-time analytics and embedded AI that only S/4HANA delivers. The complexity of the transition - particularly custom code volumes, data quality remediation, and integration rewiring - makes early, well-governed programme design the difference between a controlled transformation and a crisis migration.

Why QuickHire

Why Enterprises Choose QuickHire

01

All Three Migration Approaches

Our consultants are certified across greenfield, brownfield system conversion, and selective data transition. We match the approach to your business objectives rather than defaulting to one methodology.

02

Fit-to-Standard Rigour

We run structured fit-to-standard workshops for every in-scope module before any build activity commences. This eliminates scope creep and ensures configuration decisions are made by the right business stakeholders.

03

Data Migration Factory

Our data migration team operates as a parallel workstream - not a final-phase activity. Running mock migrations from Week 4 ensures data quality issues surface early and reconciliation rates improve iteratively.

04

Custom Code Remediation at Scale

We combine SAP CCMW tooling with experienced ABAP developers who understand business context. Each remediated object is unit-tested and regression-tested before being transported forward.

05

Integration Architecture Expertise

Whether your landscape uses SAP Integration Suite, third-party middleware, or direct API connections, our integration architects design patterns that survive go-live and scale with your business.

06

Proven Hypercare Model

Our four-to-eight week hypercare commitment includes on-site support, accelerated ticket SLAs, daily war-room calls, and formal stabilisation sign-off criteria before transition to steady-state.

Challenges

Common Enterprise Pain Points

01

Custom Code Volume and Incompatibility

Large ECC landscapes commonly contain thousands of custom ABAP objects, many of which reference deprecated tables or APIs that no longer exist in S/4HANA. Without a structured remediation workstream, these blockers surface during testing and compress the cutover window.

02

Data Quality and Migration Complexity

Decades of transactional data accumulated in ECC often contains duplicates, referential integrity violations, and incomplete master data records. S/4HANA's simplified data model is less tolerant of these inconsistencies, making pre-migration cleansing a programme-critical activity.

03

Business Process Change Resistance

Fit-to-standard decisions require business process owners to accept standard SAP processes in place of long-established custom workflows. Without strong executive sponsorship and a disciplined change management programme, these decisions stall and scope creep follows.

04

Integration Rewiring Across the Landscape

S/4HANA changes the API surface area and message formats that downstream systems depend on. Cataloguing every integration point, redesigning affected interfaces, and testing end-to-end process chains is frequently underestimated in project scoping.

05

Cutover Window and Business Continuity Risk

Production cutovers for complex S/4HANA migrations require coordinated blackout windows during which business transactions cannot be processed. Managing the tension between minimising downtime and completing all cutover tasks safely is one of the highest-stakes activities in the programme.

Our Approach

A Structured Programme Methodology Built for S/4HANA Complexity

Our S/4HANA delivery methodology follows SAP Activate with enhancements drawn from hundreds of enterprise ERP programmes. We front-load risk identification through comprehensive discovery, run data migration and custom code remediation as parallel workstreams during the build phase, and invest heavily in testing cycles and cutover rehearsals so that the go-live event is a planned, validated transition - not an experiment.

01
Migration Strategy and Discovery
We assess your ECC landscape, quantify custom code and data migration complexity, and recommend the optimal migration approach with a fully costed programme roadmap.
02
Fit-to-Standard and Business Blueprint
Structured module-by-module workshops produce a validated business blueprint, gap list, and configuration workbook before any technical build begins.
03
Build, Remediation, and Integration
Parallel workstreams handle S/4HANA configuration, ABAP custom code remediation, data migration development, and integration build with weekly cross-track synchronisation.
04
Testing, Cutover, and Hypercare
Unit, integration, UAT, and performance testing cycles culminate in multiple cutover rehearsals and a go-live followed by our structured hypercare and stabilisation programme.

Case Studies

Enterprise Outcomes

Manufacturing

A global industrial manufacturer running SAP ECC 6.0 across 14 company codes needed to migrate to S/4HANA ahead of the 2027 maintenance deadline.

We delivered a brownfield system conversion using a phased rollout strategy, remediating over 3,200 custom ABAP objects and running eight mock migration cycles to achieve a 99.2% data reconciliation rate at go-live.

34%reduction in period-end close duration post-migration
Consumer Goods

A FMCG organisation needed to carve out two divested business units from their ECC system and establish them on an independent S/4HANA platform within a 14-month timeline.

We designed and executed a selective data transition using SLT replication for real-time cutover synchronisation, migrating six years of historical transactional data and all open items with zero financial reconciliation discrepancies.

$2.1Mavoided in premium extended maintenance fees
Chemicals

A specialty chemicals company sought to replace a heavily customised ECC system with a standard-process S/4HANA environment to reduce ongoing maintenance cost.

Our fit-to-standard programme eliminated 60% of existing custom development through process redesign, with the remaining custom code fully remediated and regression-tested over a 22-month greenfield implementation.

Frequently Asked Questions

A greenfield implementation starts fresh on S/4HANA without carrying over existing ECC configurations, offering the opportunity to adopt standard SAP best practices and simplify processes from the ground up. A brownfield approach converts your existing SAP ECC system directly to S/4HANA, preserving historical transactional data, customisations, and configurations while upgrading the technical foundation. The choice depends on your appetite for process transformation, the volume of custom development in your current landscape, and the business disruption tolerance your organisation can sustain. Our fit-to-standard workshops help you quantify the trade-offs before committing to an approach.
Selective data transition - also known as a shell conversion - allows organisations to migrate only a subset of entities, company codes, or historical periods from an existing SAP system into a new S/4HANA environment. This is particularly relevant for organisations divesting business units, consolidating multiple ECC systems into a single S/4HANA tenant, or wanting a clean cutover without legacy open items. The approach uses SAP Landscape Transformation Replication Server (SLT) and specialised migration objects to move precisely scoped data sets. It reduces data migration risk but requires careful mapping of financial carryforwards and open document migration.
Programme duration varies considerably based on the chosen migration approach, the complexity of the existing ECC landscape, and the number of modules in scope. Greenfield implementations for a mid-market organisation typically run 12 to 18 months from project initiation to go-live. Full brownfield system conversions for large enterprises with significant custom development and multi-country rollouts commonly take 18 to 24 months. Our programme planning methodology breaks the timeline into discrete phases - discovery, fit-to-standard, build, testing, cutover rehearsal, and hypercare - so that milestones are clearly visible and dependencies are managed proactively.
A fit-to-standard analysis is a structured series of workshops in which your business process owners evaluate SAP S/4HANA standard functionality against your current process requirements. The objective is to identify where standard S/4HANA processes can be adopted as-is, where configuration is needed, and where genuine gaps exist that may require custom development or third-party solutions. This analysis directly informs the business blueprint, the scope of custom code remediation, and the overall implementation effort estimate. Organisations that skip or abbreviate the fit-to-standard phase frequently encounter scope creep and budget overruns during the build phase.
SAP provides the Custom Code Migration Worklist (CCMW) and the Adaptation Transport Organiser (ATO) toolset to scan your existing ABAP codebase and flag incompatibilities with S/4HANA. Our team runs these analyses in a sandbox environment to categorise custom objects by impact severity - critical blockers, functional changes, and performance optimisation candidates. Each object is then remediated by certified ABAP developers who understand both the S/4HANA simplified data model and the original business intent of the code. Remediation is followed by unit testing and regression testing to confirm functional parity before transport to quality and production systems.
Legacy System Migration Workbench (LSMW) is appropriate for structured, low-volume master data migration where business users need to map fields manually and validate records interactively. SAP Business Objects Data Services (BODS) is suited to high-volume, complex data transformations where ETL pipelines need to cleanse, deduplicate, and enrich data before loading into S/4HANA. SAP Landscape Transformation Replication Server (SLT) is the tool of choice for real-time replication during go-live cutover windows, selective data transition scenarios, and continuous synchronisation between source and target systems. Our data migration architects select the appropriate toolchain based on data volumes, transformation complexity, cutover window constraints, and the criticality of near-zero downtime requirements.
Poor data quality is one of the most common causes of S/4HANA go-live delays and post-cutover issues. Our data migration methodology starts with a comprehensive data assessment that profiles completeness, accuracy, consistency, and referential integrity across key objects including customer and vendor master, material master, open purchase orders, and financial documents. We work with your data stewards to define cleansing rules, establish ownership, and execute remediation iteratively through multiple mock migration cycles. Each mock migration produces reconciliation reports that track error rates and allow cleansing actions to be validated before the production cutover.
SAP S/4HANA exposes business processes through SAP Integration Suite, which provides pre-built integration content packages for common scenarios such as Ariba procurement, Concur travel, Salesforce CRM, and third-party logistics platforms. For bespoke integrations, our architects design event-driven patterns using SAP Event Mesh or direct API connections using OData and SOAP services exposed through the S/4HANA API Business Hub. We document all integration points in an integration architecture catalogue, implement error handling and monitoring through SAP Alert Management, and conduct end-to-end integration testing across the full process chain before go-live.
S/4HANA introduces a significantly different user experience through SAP Fiori, and process changes resulting from fit-to-standard decisions mean end users cannot simply rely on their existing ECC muscle memory. Our change management programme begins with a stakeholder impact assessment that maps role-based process changes to affected user populations. Training content is developed in collaboration with your functional leads and delivered through a combination of instructor-led workshops, e-learning modules, and sandbox practice environments. We train super-users first so they become embedded champions who can support colleagues during the hypercare period immediately after go-live.
Hypercare is the intensive support period immediately following go-live during which the implementation team remains on-site or on-call to resolve issues, answer user questions, and stabilise the system under real production load. Our standard hypercare commitment is a minimum of four weeks for a single-country go-live, extending to eight weeks for multi-country rollouts or complex integrations. During hypercare we operate an accelerated ticket triage process with defined response SLAs, daily war-room calls with business process owners, and daily system monitoring dashboards covering batch job success rates, interface throughput, and user adoption metrics. Hypercare concludes with a formal stabilisation sign-off and transition to your ongoing AMS provider.
Cutover planning begins at the blueprint phase, not the week before go-live. We construct a detailed cutover runbook that sequences every task - transport imports, final data loads, interface switchovers, authorisation activations, and smoke-test scripts - with assigned owners, durations, and dependency links. Multiple cutover rehearsals are conducted in a dedicated cutover environment to validate timing estimates and identify bottlenecks. Where business requirements demand minimal downtime, we use a near-zero downtime migration approach supported by SLT replication to keep the production system available during the bulk of the technical migration, restricting the actual blackout window to the final delta load and system switch.
Most S/4HANA programmes place Finance (FI/CO) at the core because the Universal Journal is the architectural centrepiece of S/4HANA and simplifies the reconciliation between sub-ledgers and the general ledger. Procurement and Supply Chain (MM, SD, PP, WM/EWM) typically follow given their tight integration with finance. Asset Management (PM, CS), Human Capital Management (HCM or SuccessFactors), and Project Systems (PS) are included depending on the organisation. Our programme managers have delivered S/4HANA implementations spanning all major modules and can scope phased rollouts that prioritise the highest-value capabilities first while maintaining a coherent integration architecture.
S/4HANA introduces new authorisation objects, removes deprecated transactions that authorisation roles may reference, and adds Fiori-specific catalogues and groups that must be incorporated into the role design. Our security consultants conduct a role rationalisation exercise early in the project to map existing ECC roles to S/4HANA equivalents, identify orphaned or over-privileged roles, and design a simplified role concept aligned with segregation-of-duties requirements. We use SAP Access Control (GRC) where clients have it in place, and integrate authorisation testing into each testing cycle to ensure production roles are fully validated before go-live.
The most significant risks in S/4HANA programmes are scope creep driven by under-scoped fit-to-standard workshops, data quality issues discovered late in the testing cycle, custom code remediation effort underestimation, and insufficient executive sponsorship leading to delayed business decisions. Our risk mitigation approach includes a formal risk register reviewed at every programme steering committee, mandatory fit-to-standard exit criteria before advancing to build, a data migration factory that runs parallel to design and build rather than sequentially after them, and a custom code assessment completed during the project preparation phase so remediation effort is quantified before contracts are signed.
SAP S/4HANA runs exclusively on the SAP HANA in-memory database, eliminating the need for separate aggregate tables and materialised views that ECC required for performance. The data model is fundamentally simplified - for example, the Materials Management and Finance integration no longer requires reconciliation between the Controlling and Financial Accounting modules because both now write to the same Universal Journal table (ACDOCA). Deprecated tables, redundant indices, and aggregation objects that many custom programs read directly are removed, which is why custom code remediation is non-trivial. These architectural differences deliver real-time reporting, embedded analytics, and significantly faster batch processing, but they require careful planning to migrate existing custom logic safely.
Following successful go-live and stabilisation, we offer Application Management Services (AMS) covering corrective maintenance, functional configuration changes, minor enhancements, and SAP basis administration. Support is structured in tiered SLA packages ranging from business-hours coverage for organisations with mature internal teams to 24/7 global support for critical operational systems. We also provide continuous improvement retainer engagements that systematically unlock additional S/4HANA capabilities - such as Embedded Analytics, Predictive Accounting, or Material Ledger - through structured quarterly release cycles. All post-go-live engagements include regular health checks against SAP EarlyWatch Alert reports to identify performance degradation or configuration drift before it impacts end users.
