Headless CMS migration guide

Everything that goes into moving to a headless CMS — what actually changes, how long it takes, what it costs, and how to pick the right platform without losing your search and AI visibility.

A headless CMS separates content from presentation: instead of a platform that also renders your pages, you get a content API and build the front end yourself — typically React/Next.js, Vue/Nuxt, or Astro. Teams move to headless for omnichannel delivery, faster sites, a modern developer experience, and a composable stack they can swap piece by piece.

Moving from a traditional CMS or DXP to headless is a re-platform, not a port. You remodel content into typed content types, rebuild the front end, and re-implement anything the old platform did for you — templating, forms, personalization, and search. Editors also trade in-context WYSIWYG for a structured editor, so a platform’s authoring experience matters as much as its API — and every URL that changes needs a redirect to protect your rankings.

Why teams migrate to a headless CMS

Omnichannel delivery — one content source feeds a website, mobile app, email, and more.
Performance — a modern static/edge front end typically beats a monolith on Core Web Vitals.
Developer experience — build in the framework your team already likes, with content as clean JSON.
Composability — swap search, commerce, or analytics without re-platforming the whole stack.
Scale & governance — enterprise platforms add roles, workflow, localization, and multi-brand structure.

What changes when you go headless

Content model — free-form pages become typed content types; years of ad-hoc authoring surface as modeling decisions.
Front end — the entire presentation layer is rebuilt in a framework; this is the biggest cost, not the content transfer.
Editor experience — in-context WYSIWYG gives way to structured fields; preview and training protect adoption.
Integrations — forms, search, personalization, and analytics are re-wired, each with its own testing.
SEO & URLs — routes change, so a complete 301 map, preserved metadata, and post-launch monitoring are essential.

The headless CMS platforms

The most common headless destinations, and the migration guides that cover moving to each.

Contentful

Headless CMS

The enterprise default for API-first content — strong content modeling, multi-space governance, and CDN delivery, usually paired with a Next.js or Nuxt front end.

Sitecore → ContentfulAEM → ContentfulWordPress → ContentfulDrupal → Contentful

Contentstack

Headless CMS

An enterprise, composable-DXP headless platform with workflow, localization, and an automation and personalization ecosystem built around the content API.

AEM → Contentstack

Sanity

Headless CMS

A developer favorite: a fully customizable Studio, real-time collaboration, the GROQ query language, and structured Portable Text instead of raw HTML.

Sitecore → SanityWordPress → Sanity

Storyblok

Headless CMS (visual)

Headless with a real-time visual editor — the closest thing to in-context WYSIWYG in the headless world, which softens the editor-adoption gap.

WordPress → Storyblok

Strapi

Open-source headless CMS

The leading self-hostable Node.js headless CMS — the Community edition is open-source (MIT); paid Growth/Enterprise tiers add per-seat pricing. Full control, in exchange for running and securing it yourself.

Prismic

Headless CMS

Built around reusable page 'slices' (Slice Machine), so marketers assemble pages from a component library rather than free-form fields.

DatoCMS

Headless CMS

An API-first headless with a best-in-class image and asset pipeline and GraphQL delivery — strong for media-heavy, multi-locale sites.

Hygraph

GraphQL headless CMS

GraphQL-native headless (formerly GraphCMS) with content federation, letting you stitch multiple sources behind a single API.

Directus

SQL-based headless platform

A data platform that turns any SQL database into a headless API and admin app — ideal when content already lives in a database. Source-available (BSL) rather than OSI open-source since 2023.

Payload

TypeScript headless CMS

A code-first, TypeScript-native open-source headless CMS you self-host; config-as-code appeals to engineering-led teams.

Static-site frameworks (your front end)

A headless CMS has no front end of its own — you render it with a framework or static-site generator. These are the common choices; you can point a scan at a move like WordPress → Astro and get a report tailored to it.

Astro

Static site framework

A content-focused framework that ships zero JavaScript by default — excellent Core Web Vitals. Content comes from markdown/MDX Content Collections or any headless CMS.

Next.js

React framework (SSR/SSG)

The dominant React framework (SSR + static + ISR), usually paired with a headless CMS. The default front end for enterprise headless builds.

Gatsby

React static site generator

A React static site generator with a GraphQL data layer. Once the headless darling; many teams now migrate off it to Astro or Next.js.

Hugo

Static site generator (Go)

An extremely fast Go static site generator driven by markdown — popular for docs, blogs, and marketing sites that want speed and simplicity.

Eleventy

Static site generator (JS)

A lightweight, flexible JavaScript static site generator (11ty) that turns markdown and templates into a fast static site with minimal config.

FAQ

Headless CMS migration: FAQ

Is a headless CMS worth it?

Headless pays off when you publish to more than a website (apps, kiosks, email), want top-tier performance, or need a composable stack you can swap piece by piece. For a single marketing site with non-technical editors and no omnichannel needs, a modern traditional CMS is often simpler and cheaper.

How long does a headless CMS migration take?

Most content-site moves run 3–6 months; larger DXP or multi-site estates run 6–12 months or more. The front-end rebuild, not the content transfer, drives the timeline — the content itself moves through APIs fairly quickly once the model is mapped.

Will editors lose the visual (WYSIWYG) editor?

Usually yes — most headless platforms replace in-context, on-page editing with a structured field editor. Storyblok offers a real-time visual editor that narrows the gap, and every platform benefits from a good preview environment, so pilot the authoring experience with real editors before you commit.

What happens to my SEO when I move to a headless CMS?

URLs almost always change, so a complete 301 redirect map is the make-or-break task. Preserve titles and meta descriptions, re-implement structured data, keep your XML sitemap current, and watch Search Console for crawl errors and Core Web Vitals for 30–90 days after launch.

Do I need developers to run a headless CMS?

Yes — headless assumes an engineering team or agency to build and maintain the front end. Content editors don't write code, but the site does not exist without a front end that someone builds and hosts.

Which headless CMS is best?

It depends on your team: Contentful and Contentstack for enterprise governance, Sanity for developer flexibility, Storyblok for editor-friendly visual editing, and Strapi, Payload, or Directus for open-source self-hosting. Match the authoring experience to your editors and the API to your stack.
