From Legacy to Leading-edge: A Global Software Leader’s AI-Driven Angular Migration

Accelerating legacy modernization with AI-powered automation

A global software company needed to migrate its application stack from AngularJS to Angular 15 to modernize its technology infrastructure and eliminate technical debt. The challenge was ensuring a seamless transition without disrupting development workflows or compromising code stability. GlobalLogic’s AI-powered solutions automated code migration, generated detailed documentation, and enabled unit testing—saving 40% effort, reducing manual rework, and accelerating project delivery.

Challenge

The client faced multiple challenges in modernizing its technology stack:

Legacy technology constraints – AngularJS was outdated, limiting performance, security, and maintainability.
High manual effort – Migrating a large codebase to Angular 15 required significant developer resources.
Knowledge gaps – Lack of complete documentation on legacy code made migration difficult.
Ensuring stability – Maintaining code quality and avoiding regressions during migration was critical.
Project timelines – Delays could impact product development cycles and business commitments.

As a result, the client sought an AI-driven solution that could streamline migration, enhance code quality, and reduce manual effort.

Value Created

GlobalLogic leveraged AI-powered solutions to accelerate the migration and reduce risk, automating key aspects of the transition from AngularJS to Angular 15. Automating code migration minimized manual rework and ensured a seamless transformation of the existing application stack.

AI-generated documentation bridged knowledge gaps in the legacy codebase, offering a clear view of the system’s architecture and making it easier for developers to maintain and enhance the application after migration. AI-enabled unit testing further ensured that the migrated code maintained high stability and performance, reducing the risk of regressions and improving overall software quality.

This holistic approach not only streamlined the migration process but also created a more scalable, maintainable, and future-ready technology foundation.

Impact

GlobalLogic’s AI-powered approach delivered measurable benefits, transforming the migration process:

40% reduction in effort – Automation streamlined workflows, significantly cutting manual migration tasks.
15-20% time savings – Faster execution helped meet project deadlines while maintaining stability.
Improved code quality – AI-driven testing and documentation ensured high performance and maintainability.
Seamless transition – The client successfully migrated to Angular 15 without disrupting product development or business operations.

This successful migration sets the foundation for future modernization efforts, enabling the client to stay ahead with a scalable and efficient application stack.
