Support & Application Modernization

Our support & application modernization practice turns aging systems into platforms you can extend again — without a risky big-bang rewrite. We refactor legacy code, replatform to modern stacks, and use AI-assisted discovery to map technical debt, document AS-IS architecture, and plan migration with engineers owning every merge and release.

Application modernization and legacy system upgrade

Modernization services

Smartym Pro’s approach

  • 1

    Technical Audit

    We assess legacy application modernization options, map your business model to the technical reality, and propose a target architecture. AI-assisted code and dependency analysis accelerates the inventory; engineers validate findings and deliver a roadmap you can execute in phases.

  • 2

    Implementation

    Code conversion, data migration, refactoring, and redesign — plus new features, defect elimination, and architecture rebuild where needed. AI tooling supports boilerplate and test scaffolding; every change ships through your review gates and CI.

  • 3

    System testing

    Integration and regression testing, with AI-assisted test case drafts reviewed by QA. After internal sign-off, we run acceptance testing with your stakeholders.

    Delivery

    A stable release with modernized architecture, improved functionality, and documentation your team can operate — ready for ongoing support or handover.
