Proprietary SAP Migration Solution

With SAP ECC mainstream maintenance ending for relevant releases in 2027, UK organisations need a clear migration strategy. Starting early gives your business more time to assess options, address technical dependencies, and modernise without unnecessary project pressure.

Plan Your Migration With Confidence

Allow time to assess your SAP landscape, choose the right migration approach, prepare data, and coordinate deployment around critical business operations.

Improve Real-Time Business Visibility

Connect financial and operational data to support faster reporting, more informed decisions, and better visibility across business processes.

Simplify Your SAP Landscape

Review legacy customisations, reduce unnecessary complexity, and prioritise standard SAP functionality to support long-term maintainability.

Build the Right Cloud and Technology Foundation

Evaluate deployment options and establish an architecture that can support your infrastructure strategy, integration requirements, and future business needs.

Strengthen Data, Controls, and Reporting

Review data quality, access controls, financial reporting, and applicable UK tax requirements as part of your migration and solution design.

Prepare for AI and Continuous Innovation

Create a foundation for relevant analytics, automation, and SAP Business AI capabilities as your organisation's requirements evolve.

Real-Time Data Intelligence

Shift from retrospective reporting to live insights. S/4HANA’s in-memory processing enables high-speed data analysis, allowing UK leadership to make informed decisions based on live operational reality, not last week’s figures.

Cloud Agility & Reduced TCO

Optimise your infrastructure costs. Whether through RISE with SAP or a private cloud, S/4HANA scales with your business growth while significantly reducing long-term administration and maintenance overheads.

Operational Flexibility

Modernise your deployment. S/4HANA offers a broad choice of on-premise, public, or hybrid cloud options, ensuring your ERP landscape aligns perfectly with your specific UK infrastructure and security requirements.

Process Simplification

Eliminate technical debt and complex application structures. S/4HANA’s streamlined architecture centralises resources and simplifies workflows, making your core business processes more elegant, robust, and easier to manage.

Advanced User Experience

Empower your workforce with SAP Fiori. We deliver intuitive, role-based interfaces that increase productivity across the enterprise, reducing training costs and improving employee engagement through a modern digital workplace.

Continuous Innovation

Future-proof your enterprise. S/4HANA provides a native foundation for AI, Machine Learning, and advanced analytics, ensuring your business stays ahead of the curve in a rapidly evolving UK economic landscape.

Brownfield: System Conversion

Convert your existing SAP ECC environment to SAP S/4HANA while retaining relevant configuration, processes, and business data. This approach may suit organisations that want to preserve established business processes while addressing compatibility, data, and custom code requirements.

Greenfield: New Implementation

Build a new SAP S/4HANA environment around target business processes and appropriate SAP standard functionality. This approach provides an opportunity to redesign processes, reduce legacy complexity, and establish a cleaner digital core rather than automatically reproducing historical customisations.

Selective Data Transition

Combine elements of system conversion and new implementation by selecting which processes, organisational units, and historical data should move to the target system. This approach can be useful for complex landscapes that require consolidation, restructuring, or a phased transformation.

What Our AI-Assisted SAP ECC to S/4HANA Migration Services Cover

LeverX supports the full migration lifecycle, combining AI-assisted capabilities with specialist SAP delivery.

SAP ECC Assessment and Migration Planning

Evaluate the existing landscape, custom code, interfaces, add-ons, data volumes, and business processes. Establish migration priorities, identify dependencies, and develop a roadmap.

Data Migration and Management

Support extraction, profiling, cleansing, mapping, transformation, loading, validation, and reconciliation using appropriate migration tools and automation.

Custom Code Remediation and Clean Core

Assess legacy developments and identify unnecessary customisations, incompatible objects, and technical debt. Prioritise standard SAP functionality and maintainable extensions.

SAP Integration and Cloud Architecture

Review interfaces and dependencies between SAP ECC, SAP S/4HANA, non-SAP applications, cloud platforms, and third-party systems. Prepare the target integration architecture.

Testing, Cutover, and Deployment

Plan and coordinate functional testing, integration testing, regression testing, user acceptance testing, data reconciliation, cutover rehearsals, and go-live readiness.

Post-Go-Live Support and Optimisation

Stabilise the new environment, address outstanding issues, monitor relevant performance indicators, and plan improvements after the transition.

1. Assess the Existing Landscape

Review SAP ECC configuration, custom code, data structures, integrations, add-ons, infrastructure, and business processes. AI-assisted analysis can help organise technical information and identify dependencies for expert review.

2. Define the Migration Strategy

Compare Brownfield, Greenfield, and Selective Data Transition approaches. Establish scope, target architecture, data requirements, Clean Core objectives, governance, and project milestones.

3. Prepare the Source and Target Systems

Address relevant SAP prerequisites, assess custom code, prepare interfaces, define transformation rules, and establish data quality and migration validation criteria.

4. Migrate and Validate Data

Execute planned data migration cycles, apply transformation rules, compare source and target records, and investigate discrepancies. Use automated validation where appropriate and retain documented reconciliation results.

5. Test, Cut Over, and Go Live

Validate business processes, integration scenarios, authorisations, reports, and data. Rehearse cutover activities and coordinate the transition to production based on the agreed business continuity plan.

6. Stabilise and Optimise

Resolve post-go-live issues, verify critical processes, transfer knowledge, and establish operational support. Identify opportunities to improve the target environment after the initial transition.

	SAP ECC	SAP S/4HANA
Database	Compatible with traditional relational databases (such as Oracle, SQL Server, DB2, and others).	Has an exclusive SAP HANA in-memory database that enables real-time data processing and analytics.
Architecture	Has a complex architecture of multiple index and aggregate tables, which slows down data processing and reporting procedures.	Introduces a simplified data model without index and aggregate tables, accelerating transactions.
User interface	Runs on a traditional SAP GUI that is functional, but not user-friendly for new users.	It provides a role-based, intuitive SAP Fiori user experience that ensures cross-device compatibility.
User interface customization	Has very limited customization capabilities.	Users can tailor dashboards and workflows to their needs across all Fiori apps.
Extensibility	Customizations are difficult to manage, particularly during upgrades.	SAP Fiori and SAP Cloud Platform provide easier customization and extension, with more agile responses to business needs, and without heavy reliance on custom code.
Core functionality	Provides a comprehensive suite of modules, including Finance (FI), Controlling (CO), Sales and Distribution (SD), Materials Management (MM), and Production Planning (PP).	Retains the core functionality of SAP ECC and enhances it with: Universal Journal, New Cash Management, and Financial Planning & Analysis (Finance); Advanced Available-to-Promise and embedded Production Planning and Detailed Scheduling (Supply Chain); Simplified Material Ledger and embedded Extended Warehouse Management (Logistics)
Deployment options	Typically deployed on-premise, but can also be hosted in a private cloud environment, which involves large infrastructure and maintenance costs.	Offers multiple deployment models: On-premise: For organizations that require complete ERP control. Cloud: Available in private, public, or hybrid cloud setups, offering greater flexibility, lower infrastructure costs, and easier scalability. Hybrid: A mix of on-premise and cloud, allowing businesses to utilize both environments.
Integration	Integrates with other SAP and third-party systems, but often requires complex middleware solutions, such as SAP PI/PO.	Seamlessly integrates with SAP Cloud Platform, SAP Ariba, SAP SuccessFactors, and other cloud solutions.
Licensing	Is based on a perpetual license model, with costs varying depending on the number of users and modules implemented.	Offers more flexible licensing options, including subscription-based models for cloud deployments.
Costs	Costs are usually high due to the need for separate hardware, databases, and extensive maintenance.	Initial migration and potential hardware upgrade costs are usually high, but long-term operational expenses may be lower due to reduced infrastructure and maintenance (especially in cloud environments).

What Is AI-Assisted SAP ECC to S/4HANA Migration?

It is a migration approach that combines SAP expertise with AI-assisted tools and automation for activities such as data profiling, mapping, validation, reconciliation, technical analysis, and documentation. Experts remain responsible for architecture, business decisions, testing, and approval of migration results.

How Can AI Help Reduce Migration Effort?

AI-assisted tools can help process large volumes of data and technical information, identify inconsistencies, support mapping, and organise validation findings. The actual reduction in effort depends on data quality, migration complexity, and how effectively automation is incorporated into the delivery process.

Is AI-Assisted Migration Suitable for Every SAP ECC Environment?

Not every activity benefits equally from AI. The suitability depends on system complexity, data availability, custom code, integrations, tooling, and governance requirements. A migration assessment helps determine where AI-assisted automation can add practical value.

How long does a typical SAP S/4HANA migration take?

Timelines depend on landscape complexity and the chosen migration path. Typically, a strategic transition spans 6 to 12 months. We provide a detailed roadmap during the discovery phase to align with your UK fiscal year and peak operational periods.
