LeverX provides UK organisations with end-to-end SAP S/4HANA migration expertise, from migration assessment and strategy to data migration, custom-code remediation, system transformation, testing, cutover, and post-go-live optimisation.
As organisations across the UK modernise their enterprise technology landscapes, the transition from SAP ECC to SAP S/4HANA is becoming a strategic business priority. Successful migration requires more than technical system conversion. Organisations need to assess their existing SAP landscape, select the right transformation approach, manage data and custom code, modernise integrations, and minimise disruption to business operations.
LeverX is an SAP Gold Partner and SAP Global Strategic Supplier. With more than 20 years of collaboration with SAP, more than 2,200 experts, and more than 1,500 delivered projects, LeverX combines SAP consulting, engineering, data, integration, and automation capabilities to support complex S/4HANA transformation programmes.
As an SAP S/4HANA Migration Partner, LeverX helps organisations navigate the full migration lifecycle - from initial assessment and migration strategy through implementation, data management, testing, cutover, and post-go-live optimisation.
Choosing an SAP S/4HANA migration partner is not only about selecting a technical implementation provider. Organisations need a partner capable of understanding the existing SAP landscape, making strategic migration decisions, managing transformation risks, and supporting the business through go-live and beyond.
LeverX supports the full migration lifecycle:
This end-to-end approach enables organisations to address technical, data, process, and integration requirements within a coordinated S/4HANA migration programme.
A successful S/4HANA migration starts with understanding the environment being transformed.
LeverX provides SAP S/4HANA migration assessments to help organisations evaluate their current SAP landscape and establish a migration roadmap.
The assessment can cover:
LeverX analyses the existing SAP environment, architecture, system components, dependencies, and technical prerequisites for the target S/4HANA environment.
Existing custom developments are assessed to determine what should be retained, adapted, replaced, redesigned, or retired.
LeverX evaluates data quality, volumes, structures, dependencies, and migration requirements to identify where cleansing, transformation, archiving, or migration activities may be required.
Current processes are reviewed to identify opportunities for standardisation, optimisation, and redesign within S/4HANA.
Existing SAP and non-SAP integrations are assessed to identify dependencies and determine what needs to be adapted for the target architecture.
For organisations moving to SAP S/4HANA Cloud, the assessment can also consider the technical and architectural implications of the target cloud environment.
LeverX helps organisations compare Brownfield, Greenfield, Selective Data Transition, and broader landscape transformation approaches based on business and technical requirements.
LeverX states that a typical assessment takes two to six weeks, depending on the complexity of the SAP landscape.
For organisations with established SAP ECC environments, a Brownfield approach can provide a path to S/4HANA while retaining relevant processes, configuration, and business data.
As an SAP S/4HANA Migration Partner, LeverX supports Brownfield programmes across:
This approach can be particularly relevant for organisations that have invested heavily in their existing SAP environment but need to modernise the underlying platform.
For a global manufacturer of optical fibres, cables, and laser-delivery systems, LeverX supported a Brownfield migration from SAP ECC to SAP S/4HANA.
The programme covered:
The project involved the transfer of full business data to S/4HANA and required a constrained three-day cutover.
Following the migration, LeverX continued to support the customer with SAP support, configuration, and enhancements.

A Greenfield implementation allows an organisation to establish a new S/4HANA environment and redesign business processes around the target platform.
LeverX supports Greenfield programmes with:
Greenfield can be appropriate for organisations looking to move away from legacy process complexity, reduce unnecessary customisation, and establish a more standardised SAP environment.
Selective Data Transition can provide an alternative for organisations that want to transform their SAP environment without fully converting the existing system or starting completely from scratch.
LeverX supports selective transformation scenarios involving:
The approach enables organisations to determine which elements of their existing SAP environment should move to the new platform and which should not.
Large enterprises may have multiple SAP systems resulting from acquisitions, regional operations, organisational changes, or years of independent system development.
LeverX supports broader SAP landscape transformation programmes that can combine:
For complex landscapes, the migration strategy needs to consider the relationships between systems, data, business units, and processes rather than treating each SAP instance independently.
Data migration is one of the areas where an experienced migration partner can make a significant difference to the outcome of an S/4HANA transformation.
LeverX provides data-management and migration capabilities covering extraction, cleansing, transformation, validation, loading, and reconciliation across SAP and non-SAP environments.
LeverX's Data Management Platform is designed to support complex migration scenarios.
SAP AppHaus has published the LeverX use case “Facilitating Migration from Legacy ERP to SAP S/4HANA – LeverX.” The described solution combines SAP Migration Cockpit with LeverX's DMP technology and supports capabilities including:
This capability forms part of LeverX's broader approach to SAP S/4HANA migration, where data quality and transformation are addressed alongside system and process transformation.
LeverX is also applying AI and automation to selected migration activities.
The LeverX Data Management Platform can work with SAP AI technologies and SAP Business Technology Platform to support automation in areas such as:
The solution was featured in the SAP Innovation Awards 2025 under the title “Agentic AI: Revolutionizing SAP S/4HANA Data Migration with LeverX's Data Management Platform & SAP Cloud.”
The SAP-published submission reported:
These figures are reported results from the LeverX SAP Innovation Awards submission and should be considered project or business-case figures rather than independently audited industry benchmarks.
An SAP S/4HANA migration is also an opportunity to address the technical debt accumulated in an SAP ECC environment.
LeverX helps organisations assess their custom developments and determine whether functionality should be:
This approach supports SAP Clean Core objectives and can help organisations avoid transferring unnecessary legacy complexity into the new S/4HANA environment.
LeverX's capabilities include custom-code and custom-object analysis, remediation, and optimisation as part of the broader S/4HANA migration programme.
An SAP S/4HANA migration affects the wider enterprise architecture.
LeverX supports organisations in assessing and modernising integrations between SAP and non-SAP systems, including integration design, development, testing, and validation.
The migration partner role also extends to testing and cutover.
LeverX supports:
The objective is to help organisations move to S/4HANA while maintaining business continuity and reducing migration-related risk.
LeverX's SAP S/4HANA migration experience spans manufacturing, telecommunications, utilities, and industrial distribution, covering both established SAP ECC environments and more complex enterprise transformation scenarios.
LeverX supported a global manufacturer of optical fibres, cables, and laser-delivery systems with a Brownfield SAP ECC-to-S/4HANA migration. The project covered Finance, Production and Quality, Materials Management, Sales, HR, master data and SAP Basis, as well as custom-developed functionality.
The migration followed the SAP Activate methodology and required a tightly controlled three-day cutover window, as the customer needed to minimise disruption to manufacturing operations and deliveries. LeverX reports that the full business-data migration was completed within the planned timeline, followed by ongoing SAP support, configuration and enhancements.
LeverX supported Eurasia Group in its transition from SAP ECC to S/4HANA.
The programme used the SAP Activate methodology and included system analysis, custom-code assessment, business-data migration, integration testing, user training and production migration. LeverX reports that the transformation restored the system's upgradeability, provided access to new S/4HANA functionality and prepared the organisation for subsequent SAP EWM implementation.
