What Is a CMS Migration to Headless?

A headless CMS migration splits your content layer from the frontend — cutting out monolithic platforms like WordPress, Drupal, TYPO3, or Sitecore and replacing them with an API-driven backend (Supabase, Sanity, Payload) and a Next.js frontend. Pages load 2-3x faster. You get full GDPR compliance through UK/EU-hosted infrastructure. And hosting costs? They drop 40-60% once you're on serverless deployment via Vercel.

Onde os projetos falham

Legacy CMS platforms routinely score below 50 on Core Web Vitals Google demotes slow sites. Every 100ms of delay costs you 1% in conversions.
WordPress and Drupal push security patches monthly — and they break things Unpatched CMS platforms are the #1 attack vector for UK businesses right now.
Hosting costs keep climbing whenever traffic spikes Monolithic CMS servers can't scale elastically, so you're paying for peak capacity 24 hours a day whether you need it or not.
Content editors end up working around the backend rather than with it That leads to inconsistent content and SEO drift creeping across your pages.
If a previous migration attempt tanked your rankings for months, you already know how badly botched 301 redirects and missing schema markup can hurt organic traffic — sometimes permanently. Botched 301 redirects and missing schema markup can tank organic traffic permanently.
GDPR compliance gets bolted onto a stack that was never designed for it ICO fines go up to £17.5M or 4% of global turnover. A cookie consent plugin won't save you.

Conformidade

301 Redirect Mapping

We crawl every URL on your legacy CMS and build a complete redirect map before we touch anything. Canonical tags, hreflang attributes, and structured data all transfer intact.

GDPR Data Audit

We run a full audit of personal data sitting in your current CMS. Supabase Row-Level Security and UK/EU-hosted PostgreSQL handle data isolation and encryption at rest.

Zero-Downtime Deploy

Blue-green deployments via Vercel with atomic swaps keep your old site live until the new stack clears automated health checks. Nothing goes live until it's ready.

Content Schema Transform

WordPress ACF fields, Drupal Paragraphs, TYPO3 Flux elements, Sitecore Helix modules — they all map to clean headless schemas. Nothing gets left behind.

SEO Monitoring Dashboard

We watch your rankings through Google Search Console for 60 days after launch. Automated alerts flag ranking drops, crawl errors, and broken redirects the moment they show up.

Auth & Consent Migration

User accounts move to Supabase Auth with OAuth, Magic Links, and JWT. Consent tracking gets rebuilt with proper GDPR-compliant flows and full audit logs.

O que construímos

WordPress Migration

We pull posts, pages, ACF fields, media, and taxonomies from WordPress via WPGraphQL or REST API and push them straight into a headless CMS or Supabase.

Drupal Migration

Drupal entities, paragraphs, and media export via JSON:API, with full content modelling into Sanity or Payload schemas.

TYPO3 Migration

Custom extraction scripts pull Flux elements, TemplaVoilà templates, and extension data out of TYPO3 into structured headless content.

Sitecore Migration

Sitecore migrations are a different animal — they involve Helix module decomposition and content tree export. We've built this process specifically for enterprise-scale projects running 50,000+ assets.

Supabase Backend

We configure PostgreSQL, Edge Functions, Realtime subscriptions, and Row-Level Security around your migrated data layer.

Next.js Frontend

The frontend runs on Next.js App Router with React Server Components, ISR for dynamic content, and middleware handling dynamic 301 redirects.

Nosso processo

01

Migration Audit

First, we crawl your legacy CMS — every URL, custom field, plugin, and data relationship. You get a migration feasibility report with a risk assessment and redirect map before anything moves.
Week 1-2
02

Architecture & Schema Design

Then we design the architecture. We pick your headless CMS (Sanity, Payload, or Supabase-native), design the content schema, and plan the frontend component structure. Everything gets signed off before a single line of code is written.
Week 2-3
03

Content Extraction & Transform

Data migration comes next. Automated scripts pull content via API or direct database export, clean and transform it, then load it into the new headless backend with validation at every step.
Week 3-5
04

Next.js Build & Integration

The build phase delivers a Next.js 15 frontend with App Router, wired to Supabase Auth, Edge Functions, and your headless CMS — with full 301 redirect middleware already in place.
Week 4-7
05

Zero-Downtime Cutover & Monitoring

Launch runs on Vercel via blue-green deployment. The old site stays live until every health check passes. Then 60 days of post-launch SEO monitoring with weekly reports.

Perguntas frequentes

How long does a CMS migration to Next.js take?

Most migrations take 6-10 weeks, depending on page count and how complex the CMS is. Straightforward WordPress sites under 2,000 pages finish in around 6 weeks. Enterprise Sitecore or Drupal migrations with custom modules and 50,000+ pages run 12-16 weeks. Every project kicks off with a scoped audit — no surprises.

Will I lose my Google rankings during migration?

No. We build a complete 301 redirect map before cutover, preserving every URL, canonical tag, hreflang attribute, and structured data markup. After launch, we watch Google Search Console for 60 days and fix crawl issues within 24 hours. Our clients retain 99.9% of organic traffic.

Is Supabase GDPR compliant for UK businesses?

Yes. Supabase runs EU-hosted PostgreSQL with encryption at rest and in transit. We configure Row-Level Security for data isolation, rebuild consent tracking through Supabase Auth, and make sure all personal data processing meets UK GDPR and ICO requirements. Your data doesn't leave EU data centres.

What does zero-downtime migration mean?

Your existing site stays live throughout the entire build. On cutover day, we deploy to Vercel using a blue-green deployment — the DNS switch is atomic and instant. Automated health checks verify every page before traffic moves to the new stack. Users never hit an error page.

Can you migrate custom WordPress plugins and ACF fields?

Yes. We extract Advanced Custom Fields, custom post types, WooCommerce products, Gravity Forms submissions, and plugin-specific data via WPGraphQL or REST API. Custom functionality gets rebuilt as Next.js components using Supabase Edge Functions or native headless CMS features — no plugin dependencies carried across.

How much does a website migration cost in the UK?

Simple WordPress migrations start at £10,000 for sites under 2,000 pages. Mid-market Drupal or TYPO3 projects with custom content models typically run £20,000-£40,000. Enterprise Sitecore migrations involving multi-site, multi-language, and complex data relationships start at £60,000. All quotes are fixed-fee — no hidden costs.
