Migration playbook: WordPress → Headless WordPress and Next.js

WordPress to headless Next.js migration

Keep the WordPress editor your content team knows while visitors get a fast Next.js frontend — and take WordPress itself off the public internet.

Migration drivers

Why teams make this move

Driver 01

Slow pages

Heavy themes and plugins rendering every page in PHP, which hurts Core Web Vitals and search visibility.

Driver 02

Plugin security exposure

A public attack surface from outdated plugins and the admin login page.

Driver 03

Database load under spikes

Every visit hitting MySQL, so campaign traffic slows or breaks the site.

Execution sequence

How the migration runs

Each phase ends with a check you can verify — data parity, error rates, latency — and the rollback path is agreed before any traffic moves.

  1. 01Phase

    WPGraphQL and custom fields

    Exposing content through WPGraphQL with typed custom fields.

  2. 02Phase

    Next.js frontend

    Building the frontend with Server Components, responsive images and Tailwind CSS.

  3. 03Phase

    On-demand revalidation

    WordPress webhooks that revalidate changed pages when editors publish.

  4. 04Phase

    Admin lockdown

    Moving the WordPress admin behind a VPN, SSO or IP allow-list, so it is no longer public.

Risk prevention

Pitfalls that derail this migration

Risk 01

Broken previews

Not implementing authenticated draft previews for unpublished WordPress revisions.

Risk 02

Missing SEO metadata

Forgetting to map Yoast or Rank Math fields into the Next.js Metadata API.

Risk 03

Unoptimized media

Serving raw WordPress uploads instead of passing images through next/image.

Before and after

What we measure

We take a baseline before any change and report the same numbers after cutover, from your own tools. They are the evidence of whether the migration worked — not figures promised in advance.

Questions

Frequently asked migration questions

No. Editors keep working in the WordPress editor; the Next.js frontend renders what they publish.

Visitors only reach the Next.js frontend and the CDN, not the WordPress server, so plugin vulnerabilities are no longer exposed to the public internet. WordPress still needs updates — it is just much harder to reach.
