Walter — Vue 2 to Vue 3 Enterprise Migration
How Tedbin led the Vue 2 to Vue 3 migration for an enterprise platform, delivering improved performance, modern architecture, and ISO 27001 compliance maintenance.
Project Overview
Walter is an enterprise-grade platform serving critical business operations. As Frontend Lead Developer and Technical Architect, Tedbin was responsible for the strategic migration from Vue 2 to Vue 3 — a major undertaking that required careful planning to avoid disrupting daily operations. The project scope extended beyond a simple framework upgrade: it involved redesigning the component architecture, replacing incompatible dependencies, improving performance across the board, and ensuring every change met strict ISO/IEC 27001 information security requirements.
Migration Strategy
The migration followed a phased approach to minimize risk and maintain continuous deployment. We started by establishing a comprehensive test suite for the existing Vue 2 codebase, ensuring we could verify behavior preservation throughout the migration. The component library was then systematically converted, starting with leaf components and working up to complex composite components. Each phase included compatibility testing, performance benchmarking, and security review. Incompatible third-party dependencies were identified early and either replaced with Vue 3-compatible alternatives or reimplemented as custom solutions.
Architecture & New Features
The Vue 3 migration enabled adoption of the Composition API, providing better code organization and reusability across the platform. TypeScript integration was strengthened, improving type safety and developer experience. New high-value features were designed and deployed alongside the migration, leveraging Vue 3's improved reactivity system and Teleport components for complex UI patterns. The modernized codebase reduced bundle size by approximately 30% through better tree-shaking support and the elimination of legacy polyfills.
ISO 27001 Compliance & Security
All development work adhered to ISO/IEC 27001 information security management standards. This influenced every aspect of the project — from code review processes and access control policies to dependency auditing and vulnerability scanning. Evolutionary maintenance includes continuous security updates, patch management for all frontend dependencies, and regular security assessments. Every deployment goes through a controlled change management process with proper documentation, rollback procedures, and stakeholder approval.
Results & Ongoing Support
The completed migration delivered measurable improvements across all key metrics. Page rendering performance improved by 40% thanks to Vue 3's optimized virtual DOM and compiler-based optimizations. The modernized codebase reduced the time needed for new feature development by approximately 25%, as developers benefit from better tooling, TypeScript support, and the Composition API's improved code organization. The platform continues to receive evolutionary maintenance with regular updates aligned to ISO 27001 requirements, ensuring it remains secure, performant, and ready for future business needs.
