Introduction
Many SMEs struggle with legacy systems that work reliably but block innovation. Whether it is an outdated ERP, custom-built specialist solutions or sprawling Excel landscapes — legacy systems tie up resources, prevent integration and create risks due to a lack of support and missing security updates.
Modernisation does not necessarily mean replacing everything. Synergie-Services takes a pragmatic approach with three strategies: wrapping (the legacy system stays in place and is extended with a modern API layer), step-by-step migration (modules are replaced one after another) and rebuilding (only where the technology is severely outdated). Which strategy is used depends on a thorough cost-benefit analysis.
Key aspects
Risk analysis of existing systems
Each legacy system is assessed against five criteria: technical risk, business criticality, maintenance costs, integration capability and strategic relevance. This produces a clear order of priority.
Step-by-step migration
The most tried-and-tested strategy for SMEs is step-by-step migration. It minimises risk and allows investment to be spread over several financial years.
Data migration as the key
The most critical aspect of any modernisation is data migration. A structured migration plan with data cleansing, mapping and comprehensive testing is essential.
Conclusion
Legacy modernisation is not an IT project — it is a strategic investment in future-proofing your company. Talk to us about your modernisation strategy.
