Next.js Migration Services for Teams Outgrowing Legacy Frontends
Move to App Router and modern performance patterns without disrupting the business.
We migrate websites and applications to modern Next.js so your team gets better performance, better SEO, cleaner deployment workflows, and a codebase that is easier to extend. Whether you're moving from the Pages Router, CRA, Vite, an older React stack, or a legacy marketing site, we plan the migration to protect search traffic, preserve critical functionality, and avoid risky all-at-once rewrites.
Why teams choose us
Phased Migration Instead of Risky Rewrites
We break migrations into controlled slices: routing, layouts, SEO-critical pages, data fetching, and design system updates. That reduces business risk and lets your team keep shipping while the migration is underway.
SEO and URL Equity Protected
Search traffic is usually the biggest migration risk. We preserve route structures where possible, implement redirects where needed, maintain metadata and schema, and verify crawlability before and after launch.
Cleaner Delivery for Engineering Teams
A successful migration should improve developer experience as well as runtime performance. We modernize the component structure, data boundaries, deployment pipeline, and rendering strategy so the codebase is easier to maintain long after the migration ends.
How we work
A clear, repeatable process — no surprises.
Audit the Existing Frontend
We review routing, shared components, third-party integrations, SEO dependencies, analytics, and deployment constraints. This tells us what must be preserved, what can be simplified, and what is already creating technical debt.
Define the Migration Plan
We choose the target architecture, prioritize high-value pages and flows, and decide whether the move should happen incrementally or as a controlled cutover. Redirect mapping and tracking continuity are planned up front.
Rebuild and Validate in Parallel
We migrate layouts, pages, and components to Next.js patterns such as server rendering, metadata APIs, route segments, and streaming where appropriate. Every migration milestone is validated for SEO, performance, and behavioral parity.
Launch With Monitoring
We ship the migration with redirect checks, crawl validation, analytics verification, and rollback safety. After launch, we monitor rankings, errors, and runtime metrics to catch regressions early.
Tech stack
What we build
Common use cases and project types.
- Migrating Create React App marketing sites to SEO-friendly Next.js
- Moving from Pages Router to App Router with modern metadata handling
- Combining marketing and app experiences into one deployable system
- Reducing JS-heavy rendering on content and landing pages
- Modernizing design systems during a frontend platform upgrade
- Improving Core Web Vitals and crawlability for revenue pages
Common migration paths we handle
| Current stack | Why teams migrate | Outcome |
|---|---|---|
| Create React App | Weak SEO and aging build setup | Server-rendered pages, better performance, easier deployment |
| Vite SPA | Great DX but poor content discoverability | Hybrid rendering with SEO-ready landing pages |
| Older Next.js | Legacy patterns and maintenance drag | Modern App Router architecture and cleaner route boundaries |
Frequently asked questions
Can you migrate an existing React or Vite app to Next.js without losing SEO?
Yes. For SEO-sensitive projects, we start by mapping current URLs, metadata, schema, internal linking, and indexable page types. We preserve route equity wherever possible and add explicit redirects when URLs must change. We also verify rendering, crawlability, canonicals, and analytics before launch so the migration protects existing search performance.
Do we need to rewrite the entire frontend at once?
Usually not. Most migrations are safer when phased. We can start with landing pages, blog content, or a specific product surface first, then migrate more complex application areas after the new architecture is stable. That keeps risk manageable and allows for faster business wins.
Will a migration improve performance automatically?
Not automatically, but it creates the conditions for meaningful gains. The real improvements come from better rendering strategy, less unnecessary client-side JavaScript, optimized images and fonts, cleaner data fetching, and removal of legacy bloat. We treat performance as an explicit migration deliverable, not a side effect.
How long does a typical migration take?
A focused marketing-site migration can take 2-4 weeks. A larger app migration involving shared components, account flows, dashboards, or CMS dependencies usually takes longer and is best handled in phases. We scope the migration around business risk and traffic importance, not just line count.
Why hire a team for Next.js migration services instead of letting the internal team do it gradually?
Internal teams can absolutely own migrations, but the problem is usually prioritization and migration design. A specialist team helps define the safest path, avoid SEO mistakes, modernize architecture while moving, and accelerate the work without forcing your product team to pause feature delivery for months.
