What is SAP Migration
and who needs it?
SAP migration is the transfer of business data, users, and processes from a current ERP to SAP S/4HANA or SAP Business One. It becomes relevant for organizations running SAP ECC, whose mainstream support ends in 2027, a legacy non-SAP ERP, or a fragmented system that no longer supports their growth.
Any business running SAP ECC, an older legacy ERP, or a set of disconnected tools will need an SAP migration at some point.
| Current status | Migration type | Recommended SAP destination | Urgency |
|---|---|---|---|
| Using SAP ECC (EHP 6 – 8) | ECC to SAP S/4HANA | SAP S/4HANA, cloud or on-premise | Critical: 2027 deadline |
| Using Microsoft Dynamics GP, NAV, or AX | Legacy ERP to SAP | SAP Business One or SAP S/4HANA | High: GP support ends 2029 |
| Running several legacy systems after an acquisition | Consolidation onto SAP | SAP S/4HANA, multi-entity | High: operational risk |
| Using Tally, QuickBooks, or a custom ERP | Non-SAP to SAP | SAP Business AI | When growth requires it |
| On on-premise SAP, want cloud benefits | On-premise to cloud | RISE with SAP or SAP S/4HANA Cloud | Strategic priority |
Our expertise in SAP migration
We migrate SAP ECC systems to SAP S/4HANA through Brownfield, Greenfield, Bluefield or selective data transition, selecting the method that suits your landscape. Each project is scoped, planned, and delivered before mainstream ECC support ends in 2027, with essential customizations retained and accumulated technical debt cleared in the process.
We move on-premise SAP environments to public, private, or hybrid cloud, including both editions of SAP S/4HANA Cloud and RISE with SAP. Our engineers handle data migration, system configuration, integration testing, and post go-live support, holding security and compliance at every stage.
We relocate the full SAP ecosystem, from databases and applications to integrations, onto new hardware or platforms with no data loss. The service covers OS and database migrations, Unicode conversions, and system consolidation that reduces server footprint by up to 50%.
We assess your current SAP environment, identify the risks, and design a migration strategy to match. Our consultants map system dependencies, calculate total cost of ownership, and build a phased roadmap that limits disruption and protects return on investment.

FAQ
It depends on the approach, your data volume, the level of customization, and your business requirements. As a general guide, Brownfield migrations run 6 to 10 months, Bluefield 9 to 18 months, and Greenfield 12 to 18 months, plus 2 to 3 months for assessment and planning. Starting early is the single best way to reduce risk and keep the project on track.
Mainstream support for SAP ECC ends on 31 December 2027, after which you stop receiving regular updates, security patches, and regulatory changes. Extended maintenance is available until 2030 at additional cost, but it is a stopgap rather than a solution. Migration is no longer a question of if, only when, and beginning early lowers both cost and risk.
Cost depends on the migration approach, system complexity, customizations, data quality, and the number of modules and integrations involved. Because no two environments are alike, an accurate figure requires a proper assessment of your current setup. We run a migration readiness assessment before any implementation begins, which is where a reliable estimate comes from.
SAP S/4HANA uses updated APIs, so existing integrations are rebuilt as part of the project. Our team maps every connection point, reworks each one, and tests thoroughly before switchover. Your other business systems keep running throughout, since we maintain temporary interfaces until the new ones are ready.
