SAP S/4HANA implementation and migration before ECC end of support (2027)
We move your ERP to S/4HANA with the right path for your case — brownfield, greenfield or selective — and SAP Activate methodology. Clean core and Fiori from day one so you do not drag ECC technical debt into the new system. Demos every 2 weeks, verifiable deliverables and configuration and code that are 100% yours.
SAP S/4HANA is SAP’s next-generation ERP suite on the in-memory HANA database: real-time processes, a simplified data model and the Fiori user experience.
The decision to migrate has a deadline: mainstream support for SAP ECC 6.0 / Business Suite 7 ends in 2027 (with paid extended support through 2030), so after that there are no security patches or standard support. We do the implementation and migration with SAP Activate methodology and the path that makes sense for your landscape: brownfield (conversion of the existing system), greenfield (a fresh redesign with clean processes) or selective (selective transition, the best of both).
The code and configuration are 100% yours from day one.

ERP with CFDI 4.0 invoicing
We implement Odoo with integrated SAT stamping (PAC), client portal and reconciliation — a full operation, not just software.
When you need it
What it includes
Assessment and path decision
Analysis of your landscape, data and custom code with SAP tools (Readiness Check, Custom Code Migration where it applies) to recommend brownfield, greenfield or selective with arguments, not by default.
Brownfield migration
Conversion of the existing ECC system to S/4HANA preserving history and configuration, with custom code remediation and process adjustment to the simplified S/4HANA model.
Greenfield implementation
A fresh implementation with standard fit-to-standard processes, clean core from the start and selective migration of the master data and balances you actually need.
Selective transition
A hybrid approach that migrates the data and processes worth keeping and redesigns the rest, useful when neither pure brownfield nor greenfield fits.
Data migration and validation
Cleanup, mapping and load strategy for master and transactional data, with reconciliation reports and validation prior to go-live so you do not migrate garbage.
Clean core and Fiori apps
Extensions on BTP instead of Z objects in the core, and Fiori apps (Elements or freestyle) that replace classic transactions and improve adoption.
Cutover, go-live and support
Cutover plan with a defined rollback, acceptance testing, controlled go-live and post-launch hypercare support to stabilize operations.
QA and documented handoff with ARIA
Functional, integration and regression testing backed by our internal ARIA platform, with documented configuration and code that is 100% yours.
How we work
1Prepare
We define scope, team, governance and work plan, set up the S/4HANA environments and run the Readiness Check to set the path (brownfield / greenfield / selective).
2Explore
We analyze as-is processes and design the to-be with fit-to-standard, identify gaps and decide build vs. configure, validated with your key users.
3Realize
Configuration, Fiori/ABAP development with clean core, integrations and data migration in 2-week sprints with continuous demos and validations.
4Deploy
Training, cutover plan, final data migration, acceptance testing and controlled go-live with a defined rollback plan.
5RunDeliverableconfiguration, code and runbook that are 100% yours
Post-go-live hypercare, performance monitoring, continuous optimization and an adoption roadmap, with the option to continue under AMS support.
Tech stack
The tools and platforms we build it with — chosen for your problem, not for hype.

SAP set the end of mainstream support for Business Suite 7 (which includes ECC 6.0) at 2027, with the option of paid extended support through 2030. After that window, there are no security patches or standard support except for special contracts at significant cost. That is why it pays to start the migration plan early: the closer the date, the more saturated and expensive consultants become.
Brownfield, greenfield or selective? Which suits me?
It depends. Brownfield (conversion) preserves your configuration and history and is faster, but drags technical debt if you do not remediate it. Greenfield (a new implementation) gives you clean processes and clean core, but means redesigning and takes more effort. Selective migrates what is worth keeping and redesigns the rest. We do not decide by default: we run the Readiness Check and analyze your custom code and processes before recommending, with arguments.
How long does an S/4HANA migration take?
As an estimate, a typical brownfield takes 6 to 12 months depending on module count, data volume and customization complexity; a greenfield can run 9 to 18 months as it involves redesigning processes. Critical factors are data cleanup, custom ABAP code remediation and training. We recommend starting at least 18 months before the support deadline.
What are RISE and GROW with SAP?
RISE with SAP is SAP’s offering that bundles S/4HANA Cloud, infrastructure and services into a subscription, aimed at companies migrating their existing ERP to the cloud. GROW with SAP targets new cloud implementations, typically for companies starting on S/4HANA Cloud public edition. We help you size which one fits your case, scope and budget, with no unnecessary licenses.
Do we own the configuration and code?
Yes, 100%. All configuration, Fiori/ABAP developments and BTP extensions are delivered documented and are your property, with no vendor lock-in. We apply clean core so your extensions live outside the standard and do not break future upgrades. We are a partner within the SAP ecosystem: the system lives inside your landscape, maintainable by any competent team.
