Why Migrate to SAP S/4HANA?
-
Prepare for the Future of SAP
As SAP ECC approaches the end of mainstream maintenance, organisations need a clear migration strategy to manage technical dependencies, minimise disruption, and plan the transition to S/4HANA.
-
Build an AI-Ready Digital Core
SAP S/4HANA provides a modern foundation for analytics, automation, and AI. Clean data, streamlined processes, and a maintainable core help organisations make better use of these capabilities.
-
Modernise Business Processes
Migration creates an opportunity to review processes, retire unnecessary customisations, and adopt SAP standard functionality where appropriate. LeverX helps align the target environment with your current and future business needs.
-
Accelerate Migration with AI and Automation
LeverX uses AI-assisted tools and automation to support data analysis, mapping, validation, reconciliation, and other migration activities. Our Data Management Platform helps reduce manual effort and improve migration efficiency.

Evaluation and Migration Planning
We assess your existing SAP environment and wider IT landscape to understand the systems, business processes, integrations, custom developments, data, and technical dependencies involved in the migration.
The assessment can include:
- Analysis of the existing SAP landscape and system dependencies
- Assessment of customisations and custom developments
- Identification of integration and technical dependencies
- Analysis of data volumes, quality, and migration requirements
- Identification of technical and functional risks
- Evaluation of migration requirements and constraints
- Definition of the migration roadmap and key activities
Where the starting environment is SAP ECC, we assess the specific technical and functional requirements associated with the transition to SAP S/4HANA. For other SAP landscapes, the assessment is adapted to the relevant source systems and migration scenario.
AI-assisted analysis and automation can support the assessment of large volumes of technical and system information, helping teams identify dependencies and potential areas of risk more efficiently.
System Preparation
Before migration, we prepare the existing SAP landscape and target environment for the SAP S/4HANA transition.
Depending on the source environment and selected migration approach, preparation activities can include:
- Required SAP system updates and technical preparation
- Custom code analysis and remediation planning
- Identification of obsolete or redundant developments
- Analysis of technical debt
- Preparation for SAP S/4HANA-specific requirements
- Integration and interface preparation
- Activities supporting a Clean Core strategy
For SAP ECC-based migrations, this can include the technical and functional preparation required for the transition from ECC to SAP S/4HANA.
The objective is to address relevant technical issues before migration and reduce unnecessary complexity in the target environment.
Data Migration
We support the extraction, transformation, and loading (ETL) of data from existing SAP and relevant legacy systems into the SAP S/4HANA environment.
The data migration process can include:
- Data extraction from SAP and legacy source systems
- Data profiling and quality assessment
- Data cleansing and transformation
- Mapping source data to the target structure
- Data validation and reconciliation
- Migration testing and mock migrations
- Identification of data that should be archived rather than migrated
AI-assisted tools and automation can be used where appropriate to analyse data, identify quality issues, and support transformation and validation activities.
This approach helps maintain data consistency and provides visibility into migration results before go-live.
Custom Code and Development Remediation
Existing custom developments, including custom ABAP code where applicable, are assessed for SAP S/4HANA compatibility, business relevance, and alignment with Clean Core principles.
We identify:
- Custom code requiring remediation
- Developments affected by SAP S/4HANA changes
- Obsolete or unused customisations
- Developments that can be replaced with standard SAP functionality
- Opportunities to reduce unnecessary custom code
Business-critical developments are remediated and tested as required. Functional and technical testing verifies that relevant custom processes operate correctly in the SAP S/4HANA environment.
Testing, Training, and Business Readiness
Migration requires both technical validation and preparation of business users.
We support testing activities across the migration lifecycle, including:
- Unit and technical testing
- Integration testing
- End-to-end business process testing
- Data validation
- Regression testing
- User acceptance testing
- Defect identification and resolution
We also support role-based user training, training documentation, and business-readiness activities. Training is aligned with the processes and functionality users will work with in the SAP S/4HANA environment.
Go-Live and Post-Migration Support
Our support continues through go-live and the initial stabilisation period.
Post-migration activities can include:
- Resolution of post-go-live issues
- System and process monitoring
- Performance analysis
- User support
- Data and process validation
- Defect management
- Knowledge transfer to internal teams
Once the SAP S/4HANA environment is stable, we can support further optimisation and the adoption of capabilities across SAP BTP, automation, analytics, and AI, based on the organisation's business and technology priorities.

FAQ
What is SAP S/4HANA migration, and why is it important?
SAP S/4HANA migration is the transition from legacy SAP ECC systems to SAP’s next-generation, AI-powered ERP platform. Unlike a simple upgrade, this migration moves your business onto the HANA in-memory database, providing real-time analytics and a modern user experience via SAP Fiori.
Why it is critical for your business today:
- The 2027 Deadline: SAP will end mainstream support for legacy ECC systems in 2027. Planning your S/4HANA transition roadmap now is essential to avoid business disruption and talent shortages as the deadline approaches.
- Operational Agility: It enables a Clean Core strategy, allowing you to adopt new features and SAP Business AI innovations without the complexity of traditional, heavily customised legacy systems.
- Real-Time Data Sovereignty: For UK enterprises, S/4HANA provides superior visibility into supply chains and financial reporting (HMRC/MTD), allowing for faster decision-making based on live data rather than retrospective reports.
- Cloud-First Innovation: Through RISE with SAP, migration becomes a gateway to digital transformation, offering scalable infrastructure that reduces long-term Total Cost of Ownership (TCO).
Bottom line: Migration is no longer just a technical necessity - it is a strategic move to ensure your business remains competitive, compliant, and ready for the future of AI-driven commerce.
Which SAP S/4HANA migration approach is best for our business?
The ideal path depends on your legacy complexity and your vision for the future. We specialize in three primary strategies:
- Greenfield (New Implementation): Best if you want a "fresh start." You’ll move to a Clean Core by redesigning processes from scratch and abandoning years of custom code.
Ideal for: Businesses seeking total transformation or moving from non-SAP systems. - Brownfield (System Conversion): Best for a "lift-and-shift." This preserves your existing processes and historical data while upgrading the underlying technology to S/4HANA.
Ideal for: Companies with highly optimized ECC systems who need to meet the 2027 maintenance deadline with minimal disruption. - Selective Data Transition (Bluefield): A hybrid approach that allows you to choose which data and processes to migrate. It combines the speed of Brownfield with the flexibility of Greenfield.
Ideal for: Large UK enterprises with complex global landscapes needing to consolidate or split entities.
Our Recommendation: We start with a Discovery Phase to assess your current landscape. Most UK clients now opt for a RISE with SAP framework, which can be delivered through any of these three approaches depending on your cloud readiness.
How do you reduce risk during SAP S/4HANA migration?
We minimize project risk through a structured, "safety-first" framework designed for complex UK enterprise environments:
- Pre-Migration Assessment: We use tools like SAP Readiness Check and Spotlight to identify technical bottlenecks, incompatible add-ons, and data inconsistencies before the first line of code is moved.
- Custom Code Remediation: We analyze your existing footprint to retire unused code and adapt necessary customisations, ensuring they function perfectly on the HANA database.
- Clean Core Strategy: By separating custom enhancements from the standard SAP code, we reduce the risk of future upgrade failures and lower your long-term Total Cost of Ownership (TCO).
- Rigorous Data Validation: We implement automated data cleansing and migration protocols to ensure that only high-quality, relevant data enters your new environment, preventing "garbage in, garbage out" scenarios.
- Phased Testing & Hypercare: Our approach includes multiple cycles of User Acceptance Testing (UAT) and a dedicated Hypercare period post-launch to ensure business continuity and rapid issue resolution.
- Local Governance: Having a UK-based project management team ensures real-time oversight and alignment with local compliance standards (HMRC/GDPR), eliminating the risks associated with time-zone gaps.
The Result: A predictable, transparent migration that avoids costly downtime and ensures your business remains fully operational throughout the transition.
Why choose a UK-based SAP S/4HANA migration partner?
Choosing a local partner is a strategic decision to mitigate risk and ensure your SAP S/4HANA transition roadmap aligns with British business standards.
- Local Regulatory Expertise: We ensure full compliance with HMRC’s Making Tax Digital (MTD), UK GDPR, and industry-specific regulations that offshore providers might overlook.
- Strategic Delivery Models: Whether you require a Greenfield, Brownfield, or Selective Data Transition, a UK partner provides the hands-on expertise needed for complex ECC to S/4HANA migration services.
- RISE with SAP Support: Local experts help you navigate the RISE with SAP UK offering, ensuring your cloud strategy fits the UK’s digital infrastructure and latency requirements.
- Time-Zone and Cultural Alignment: Real-time collaboration in GMT/BST ensures faster decision-making during critical Fit-to-Standard workshops and User Acceptance Testing (UAT).
- Commitment to Clean Core: We implement a SAP Clean Core strategy, reducing technical debt and ensuring your system is future-proof for Business AI and automated updates.
- On-Site Accountability: From London to Manchester, having consultants who can be on-site provides a level of security and post-go-live Managed Services (AMS) that remote teams cannot match.
Key takeaway: A UK-based partner bridges the gap between global SAP best practices and local operational realities, helping you meet the SAP 2027 maintenance deadline with confidence.
