Legacy Application Modernization

eFAIDA helps businesses streamline their legacy application modernization and legacy code migration to promote faster digital transformation journeys and build the foundation for future innovation. We revive your cumbersome legacy software by updating applications and adopting Agile methodologies, integration-ready APIs, DevOps practices, Microservices architecture, and Cloud technologies.





Legacy System Modernization Strategies
Legacy Application ModernizationLegacy Application Modernization

We unlock the new value of the front end of a legacy system by improving or enhancing its current capabilities. Our legacy system modernization services breathe a new life into the back-end code if it requires a complete re-architecture. However, we can redesign or upgrade it within the current infrastructure.

Legacy Application Migration Legacy Application Migration

We ensure a seamless transition of your data, apps, infrastructure, or APIs without affecting core business logic and architecture. eFAIDA will develop a tailor-made legacy data migration strategy depending on the application and business needs while ensuring efficiency, continuity, and minimizing disruption.

Enterprise-Grade Software Development Enterprise-Grade Software Development

We replace outdated though business-critical systems or develop them from scratch. Our legacy modernization services aim to replace or redesign the complete enterprise application system when it is impossible to reuse the existing legacy business logic.

We Provide

Application Modernization Services


Our tech experts open up possibilities to encapsulate the existing legacy software and make it available for flexible open-system platforms via API.Build on the wrapping technology, which leaves the code in the current environment, We offer low-value and low-threat legacy gadget modernization to satisfy your needs.


We can move your existing applications to more efficient business platforms and preserve the existing functionality and current business logic. To adapt the code to a new platform, we modify the system components until they can run in new environments.



If you opt for rehosting as the modernization strategy, we can move an outdated software system to modern hosting solutions without significant changes to the application’s features or functions. When migrating from legacy hardware to up-to-date open systems, we enable timely UI/UX updates, performance optimization, and database migration without reformatting. Port legacy software to virtual machines using our solid platforming and refactoring know-how to ensure a future-proof, cloud-native, microservices-based architecture.


Our rearchitecting application services involve unparalleled tools and methodologies to move on from legacy systems with medium risk. We are your strategic partner in shifting to a new application architecture while transforming the code to make it ready for ecosystems with better capabilities.



With a vast pool of legacy modernization skills, we can create a reengineering plan that aligns with your visions and goals. We prioritize and modify the required tools for your long-running enterprise applications by extracting business-critical and antiquated features. As a result, we boost the system’s functionality and scalability and enhance its performance.


To smoothly substitute a legacy application and dig practical value in creating optimized code, we can refactor an application component without affecting its external behavior or functionality. With us, you will be able to remove technical debt, maximize the cost efficiency of each software part, and access UX updates just at the right time.

Rebuilding (Redesign)

Rebuilding (Redesign)

If you want to add more features, functionality, and processes on top of the current system, opt for our rebuilding application modernization services. Our legacy migration specialists will redesign the application’s parts from scratch without modifying their specifications to perform similar functions.

Our Work Speaks for Itself


Need Help? We've Got You Covered!

A legacy application is a system that is based on outdated technology but remains critical to the operation of the enterprise. Due to lack of support to meet new business requirements or technological inability to scale or integrate with the latest platforms, such a system requires modernization or redesign or complete replacement in extreme cases.

We can find legacy software examples across numerous use cases within organizations. Some of them underestimate the importance of legacy application retirement, while others have already taken steps to implement legacy system modernization strategies. These examples include CRM, supply chain management and order processing systems, financial management software, business intelligence tools, billing and invoicing management platforms, and many others.

Companies need to plan out how they will approach legacy application modernization to eliminate overspending and save resources. The first step is to evaluate the obsolete system using business and IT drivers, including, among other things, lack of business agility and security risks. The next step is to weigh legacy system modernization options that vary depending on the ease of implementation. Finally, it is necessary to choose the right modernization approach based on its effect on the system’s structure, functionality, and cost.

System migration involves a transition of outdated software components to modern systems and platforms and migration from legacy systems to cloud or other premises. With a proper legacy data migration strategy, it is possible to implement necessary changes without disruption and critical data losses.

Legacy code migration to modern platforms is the need of the hour due to several reasons:

  • High costs of legacy system maintenance and support
  • Lack of compliance with current industry regulations
  • Lack of integration-ready architecture
  • Shortage of specialists proficient in outdated languages like COBOL
  • Lost opportunities for future growth due to the system’s inability to evolve
  • Lack of business agility to adapt to market challenges.

When tasked with how to migrate legacy applications to the cloud, go through the following steps:

  • Test feasibility of moving your application to the cloud;
  • Evaluate the existing infrastructure of both physical and virtual workspaces;
  • Choose an appropriate migration strategy ( lift and shift, re-platforming, rearchitecting, etc.);
  • Deploy a test migration to gain user feedback and identify potential issues;
  • Move the existing legacy system to the cloud;
  • Conduct continuous monitoring and optimization of the cloud environment.
