Enterprise Application Modernisation with Low-Code

In many enterprise organisations, application modernisation does not occur through complete replacements, but rather through progressive evolution. Critical systems continue to support the business, while new digital needs emerge around them, requiring more modern interfaces, greater agility and better integration. 

In this context, low-code emerges as a pragmatic way to modernise existing applications, creating new functional layers and improving the user experience without deep interventions in core systems. 

Modernising is not replacing 

One of the most common misconceptions about application modernisation is assuming that evolution means rewriting or replacing existing systems. In practice, most organisations aim to: 

• Extend the lifespan of critical applications 

• Improve usability and operational efficiency 

• Reduce dependency on complex development 

• Prepare the portfolio for future evolution 

Low-code fits well in this incremental model, acting as a modernisation layer over existing systems rather than a total alternative to traditional development. 

Where low-code is most effective in modernisation 

In application modernisation programmes, low-code tends to generate more value when applied to specific components of the ecosystem: 

• User interfaces – Renewing digital experiences without changing existing business logic 

• Orchestration layers – Consolidating processes involving multiple systems 

• Functional extensions – Adding new capabilities to legacy applications 

• Operational flow automation – Reducing manual tasks and informal dependencies 

These uses enable visible and rapid modernisation while maintaining stability in the most critical systems. 

Low-code as a bridge between past and future 

Instead of creating ruptures, low-code can act as a transition element between legacy applications and more modern architectures. By creating new applications or extensions on top of existing systems, it becomes possible to: 

• Isolate technical complexity 

• Reduce pressure on traditional development teams 

• Introduce new practices and standards gradually 

• Facilitate future, deeper modernisation initiatives 

This approach is particularly relevant in organisations with extensive portfolios and historical dependencies that are difficult to eliminate in a single cycle. 

Maintaining coherence in the application ecosystem 

Even in modernisation initiatives, it is essential to ensure technical and functional coherence. Applications developed with low-code must integrate naturally with the rest of the ecosystem, respecting existing architectural, data and security principles. 

When this alignment exists, low-code helps simplify the portfolio rather than fragment it, supporting progressive and controlled modernisation. 

Our experience 

This approach has been applied in enterprise contexts to support application modernisation programmes, allowing interfaces to be renewed, processes automated and extensions created over existing systems, without compromising the stability of core systems or the coherence of the technological ecosystem. 

Enterprise application modernisation is an ongoing journey, made up of incremental decisions. Low-code can support this journey when used as an evolution tool, not as an indiscriminate replacement of existing systems.
