React Migration Services

Migrate legacy frontend codebases to modern React and Next.js architectures.

About

Many teams are stuck with legacy frontends: old React SPAs, Angular/Vue apps, jQuery layers, or SEO-blind architectures that no longer scale. We migrate these systems to modern React and Next.js in a controlled, measurable way — preserving functionality, URLs, key SEO signals, and internal logic where possible. This is not a "big bang rewrite". It is a staged migration designed for products operating in production environments.

What we migrate

Comprehensive migration services for legacy frontend architectures.

Legacy React SPAs

Migration from outdated React setups to modern React (18/19) with improved rendering, data fetching, and performance.

Angular / Vue / Mixed Frontends

Step-by-step migration to React/Next.js without breaking existing workflows.

SEO-blind architectures

SPAs migrated to SSR / SSG / ISR with proper metadata, structured data, and indexable pages.

Monolithic Frontends

Refactoring toward modular architectures and clear domain boundaries.

Performance-bottlenecked UIs

Migration combined with bundle reduction, rendering optimization, and Core Web Vitals optimization.

Typical problems we solve

Poor SEO due to client-side rendering only
Slow first load and heavy JavaScript bundles
Fragile legacy codebases that block feature development
Inconsistent UI and duplicated logic
Risky "rewrite from scratch" proposals

How we work

Step 01 — Migration Audit

Codebase analysis, dependency mapping, routing & SEO review, and risk assessment.

Step 02 — Target Architecture Design

Next.js structure (App Router / Pages), rendering strategy (SSR/SSG/ISR), data layer, and routing plan.

Step 03 — Incremental Migration

Route-by-route or module-by-module migration with parallel operation and feature parity.

Step 04 — SEO & Performance Validation

URL parity, redirects, metadata, Core Web Vitals, and regression testing.

Step 05 — Rollout & Handover

Safe rollout, documentation, and team enablement.

What you get

Modern React / Next.js architecture
Preserved URLs and analytics, with careful handling of SEO signals
Faster performance and smaller bundles
Cleaner codebase ready for long-term growth
Clear migration documentation

FAQ

FAQ

Yes — we migrate Angular, Vue, jQuery, and other legacy frontend frameworks to modern React and Next.js architectures.

No — we preserve URLs, redirects, metadata, and SEO signals throughout the migration process. Our incremental approach is designed to minimize SEO impact during migration.

Yes — we use incremental migration strategies (route-by-route or module-by-module) that allow parallel operation and deployments with minimal downtime.

Migration timelines depend on codebase size and complexity. Typical migrations often take several months for medium-sized applications, with incremental rollouts throughout.

We recommend and implement Next.js App Router for new migrations, but can work with Pages Router if needed. The choice depends on your requirements and timeline.
