Frontend MigrationZero-Downtime Framework Upgrades
Ship the modern stack without breaking what's live. A progressive cutover playbook — SEO parity, Core Web Vitals gains, and risk-managed rollout from pilot to handover.
The Migration Runway
Five phases from audit to handover — no big-bang rewrites, no surprise downtime.
02
Pilot
One route live on the new stack — measure, learn, iterate.
03
Parallel
Feature flags and traffic split between old and new paths.
04
Cutover
Redirects, SEO parity, schema, sitemaps, and GSC validation.
05
Handover
Docs, CI/CD, observability, and a rollback plan you trust.

Legacy vs Modern Stack
See what changes when you move from brittle legacy tooling to a framework built for speed, SEO, and scale.
Legacy Frontend
CRA, jQuery plugins, PHP templates, Vue 2 Options API
RoutingClient-only SPA, hash routes
DataAd-hoc fetch, global state sprawl
BuildWebpack 4, slow HMR, CRA eject
SEOMeta tags bolted on, poor SSR
DeployManual uploads, no preview envs
Framework Destinations
We migrate to the stack that fits your team — not a one-size template.
Next.js
App Router, RSC, SSR/ISR, and edge-ready deploys.
Nuxt
Vue 3, Nitro server, hybrid rendering, and module ecosystem.
Vue
Composition API, Vite builds, and progressive adoption.
Svelte
SvelteKit routing, adapters, and lean client bundles.
React
Modern React patterns, TypeScript, and component systems.
Not sure which framework?
We help you choose based on team skills, SEO needs, and product roadmap.
Risk-Managed Rollout
Every migration ships with guardrails — not hope and prayers.
Pilot
Route first
Ship one path on the new stack before touching the rest.
Flags
Progressive rollout
Feature flags and staged traffic for safe cutover.

Observability
Error tracking and monitoring baked in from day one.

Downtime goal
Rollback plan and staging QA before every production push.

Delivery Process
Six clear steps from discovery to a production-ready modern frontend.
01
Audit
Map architecture, dependencies, integrations, SEO footprint, and migration constraints.
02
Strategy
Choose target framework, routing model, data layer, and phased rollout plan.
03
Pilot
Migrate one route, wire CI/CD preview environments, and validate metrics.
04
Migrate
Roll out remaining routes with feature flags and parallel traffic where needed.
05
QA
Functional, regression, performance, accessibility, and compliance testing.
06
Handover
Documentation, observability setup, redirects, and team enablement.

Migration FAQ
Common questions before starting a framework migration.
Which frameworks do you migrate to?
Next.js, Nuxt, Vue, Svelte, and modern React setups — chosen based on your team skills, SEO needs, and product goals.
How do you ensure SEO isn't lost?
We keep URL parity, implement redirects, preserve meta and Open Graph data, update sitemaps and schema, and validate with Google Search Console. Core Web Vitals are improved post-migration.
What's the typical timeline?
Starter pilots take 1–2 weeks. Full migrations run 3–8 weeks depending on app size, integrations, and QA scope.
Will the site go down during migration?
No — we use a progressive rollout: pilot routes, feature flags, parallel traffic, and staging QA before cutover. A rollback plan is always in place.
How is migration different from front-end development?
Front-end development builds new UI from scratch. Migration moves an existing app to a modern framework while preserving SEO, behaviour, and business continuity.
