The Story

The client initially adopted Vue 2 for application views but faced obsolescence when Vue 3 was released. To stay updated and leverage the latest features, they decided to migrate the entire platform from Vue 2 to Vue 3. The process, however, posed significant technical challenges due to breaking changes, compatibility issues, and the complexity of refactoring a large-scale application.

The client is a technology-driven enterprise seeking to modernize its legacy .NET platform by migrating to Vue 3 for improved performance, scalability, and future-ready UI enhancements.

The challenge

• > Migrating over 20 screens and hundreds of components from Vue 2 to Vue 3.

• > Addressing compatibility issues and ensuring seamless functionality.

• > Adapting the existing codebase to Vue 3’s syntax and features.

• > Performing rigorous testing to maintain stability and prevent disruptions.

• > Executing the transition within a tight deadline./p>

The solution

The development team executed a structured migration plan, systematically upgrading the codebase to Vue 3. They utilized Vue 3’s advanced features while maintaining compatibility with existing components. Technologies such as Vuex, Storybook, and Jest were deployed for frontend optimization, while Java, Spring Boot, OPA/OPAL, KeyCloak, and Postgres ensured backend stability. Rigorous testing was conducted at each stage to ensure a seamless transition without compromising performance.

The outcome

Within a month, the migration was successfully completed, modernizing over 20 screens and hundreds of components. The transition to Vue 3 enhanced the platform’s longevity, security, and performance, enabling future UI enhancements. With a unified technology stack, the client significantly reduced downtime, minimized revenue loss, and improved overall operational efficiency.
