Why does modernizing legacy systems matter?

Many businesses rely on systems built years ago in technologies such as Yii, Drupal, CakePHP, Django, or Ruby on Rails. While these platforms once delivered value, today they often create technical debt, high maintenance costs, and limited flexibility. Employees struggle with slow, unintuitive interfaces, while IT managers face pressure to deliver new features and integrations quickly.

Choosing legacy software modernization services means turning these challenges into opportunities. Our role as a legacy modernization company is to make your internal tools future-ready. By upgrading frameworks, refactoring code, modernizing UI/UX, and adopting API-first architectures, we help your systems keep pace with business growth while maintaining complete stability.

Technologies powering our modernization services

We modernize systems by combining proven engineering practices with modern technologies. Backend layers are re-engineered using Laravel and API-first architecture, enabling easier scaling and seamless integrations with other tools. Frontend modernization is carried out with React.js, replacing outdated technologies like AngularJS or jQuery to deliver responsive, intuitive interfaces. Along the way, we focus on code refactoring, framework upgrades, and security improvements, ensuring your applications meet current standards.

Our approach to software product modernization services

Every organization has unique challenges when upgrading legacy systems. That’s why we deliver tailored software product modernization services designed around your goals. Our modernization scenarios include:

  1. Full system rewrite – a complete re-engineering of the application into a modern stack, available once migration is finished.
  2. Modular migration – a step-by-step approach where both old and new modules run in parallel, enabling smooth transition.
  3. Selective modernization – upgrading only specific layers: backend, frontend, frameworks, or UI/UX.

This flexibility allows us to upgrade legacy systems gradually, ensuring your team can continue to work without disruption.

Let’s modernize your legacy system together!

What’s included in our legacy software modernization services?

Our legacy software modernization services cover the full scope of activities needed to transform outdated ERP, CRM, CMS, or intranet platforms into modern, scalable, and secure solutions:

  • Legacy system audit and consulting

    Every software modernization process starts with an in-depth audit. We perform a detailed assessment of your existing applications, identifying technical debt, security risks, and scalability issues. Our experts highlight which modules need urgent modernization and create a roadmap that aligns with your business goals. This consulting phase ensures that when you modernize legacy systems, you achieve measurable improvements quickly, while keeping mission-critical operations stable.

  • Legacy software re-engineering

    Sometimes, incremental upgrades are not enough. Our legacy software re-engineering services focus on rebuilding outdated business logic so your applications can meet modern demands. We analyze how your current system supports workflows, then redesign or optimize components that limit performance, security, or integration. This approach transforms old systems into powerful tools ready to support automation, cloud migration, and advanced integrations.

  • Legacy system upgrade services

    Many organizations struggle with upgrading legacy systems that still power their core business but rely on outdated technologies. Our legacy system upgrade services include migrating ERP, CRM, and CMS platforms to modern architectures. This often involves backend transitions to Laravel or Node.js, frontend framework upgrades to React, and adopting API-first designs for seamless integration. With these upgrades, you can future-proof your IT landscape and remove the barriers that prevent scalability and innovation.

  • Framework and libraries upgrades

    Outdated frameworks and third-party libraries create serious security and compatibility risks. Our framework upgrades and libraries upgrades ensure that your system benefits from the latest vendor support and performance standards. For example, we migrate applications from Yii or CakePHP to Laravel, or from AngularJS to React, depending on business needs. These upgrades improve long-term sustainability, reduce technical debt, and enable smoother integration with modern SaaS platforms.

  • Frontend modernization (UI/UX)

    A successful legacy modernization company must address not only backend performance but also user experience. We provide complete UI/UX modernization by redesigning outdated interfaces into responsive, intuitive, and accessible platforms. Using React.js and modern design practices, we deliver systems that improve employee efficiency and reduce frustration. A modernized frontend empowers teams to work faster and boosts adoption of upgraded systems.

  • Data migration and integration

    When upgrading or re-engineering a system, data accuracy and security are crucial. We provide precise data migration and integration services, ensuring that business-critical information is transferred securely and consistently. Our team connects your modernized platform with ERP modules, APIs, and SaaS applications, guaranteeing that your system remains the central hub of your digital ecosystem. This step minimizes downtime and allows you to leverage new opportunities for automation and business intelligence.
