Drupal to Headless CMS Migration
Your Drupal Site Runs Fine — Until You Try to Ship Fast
Why leave Drupal?
- Hunt down a Drupal developer every time a module breaks after a core update
- Wait through multi-hour cache rebuilds just to preview a homepage tweak
- Pay premium rates for shrinking talent pool familiar with Drupal 9 or 10 internals
- Watch your Time to First Byte crawl past 2 seconds while competitors ship sub-500ms pages
- Budget $18K–$35K annually for module licenses, hosting overhead, and maintenance contracts
- Explain to your marketing team why launching a new content type requires a developer sprint
What you gain
- Ship content changes in under 8 seconds from save to live deploy across global CDN
- Hire from the React ecosystem — 12× larger talent pool than Drupal specialists
- Edit in Sanity's real-time interface where three editors collaborate without lock conflicts
- Cut infrastructure spend by 60–70% moving to serverless Next.js on Vercel or Netlify
- Run your entire CMS and frontend stack for under $400/month at 500K monthly visits
- Launch new page templates without backend developer dependency — your frontend team owns it
Full Drupal migration vs headless Drupal
There are two ways to move off Drupal's frontend. Headless Drupal keeps Drupal as the backend and replaces the theme with Next.js or Astro. This is less disruption but you still maintain Drupal.
A full migration moves content from Drupal to a modern headless CMS — Sanity, Contentful, or Storyblok — and rebuilds the frontend from scratch. More work upfront, but you end up with a significantly simpler stack with better tooling and a larger pool of developers who can maintain it.
Migrating Drupal content types
Drupal's content types map to CMS collections in Sanity or content types in Contentful. Paragraphs (Drupal's structured content module) map to block-based content in Sanity or rich text fields. I write migration scripts that transform every Drupal node into the target CMS format, preserving all field data and media references.

Launch & Monitor
DNS cutover with zero downtime. 30-day monitoring period included.
Drupal vs Sanity / Contentful + Next.js
| Metric | Drupal | Sanity / Contentful + Next.js |
|---|---|---|
| Developer availability | Limited (Drupal) | Large (React/Next.js) |
| Module/plugin updates | Complex, breaking | Simple, managed |
| Editorial interface | Drupal admin | Sanity Studio / Contentful |
| Lighthouse (mobile) | 40–70 | 90–100 |
Common questions
Which headless CMS should I migrate Drupal content to?
Sanity for developer-first teams who need maximum flexibility. Contentful for enterprise teams that prioritise stability and integrations. Storyblok if your editorial team wants visual page editing. I assess your content model and team workflow before recommending.
How complex is migrating Drupal Paragraphs?
Drupal Paragraphs are structured content blocks. They map well to Sanity's portable text or Storyblok's components. The migration requires mapping each paragraph type to its CMS equivalent — this is the most complex part of a Drupal migration but fully achievable.
Will we lose any content in the migration?
No. I write migration scripts that validate every node before and after migration. Content counts, field values, and media references are all verified. Nothing is published until validation passes.
How long does a full Drupal to headless CMS migration take?
Depends on content complexity. A site with 10-20 content types and under 10,000 nodes takes 6-8 weeks. A large enterprise site with 50+ content types and 100,000+ nodes takes 12-20 weeks.
What happens to Drupal workflows and moderation states?
Content workflows (draft, review, published) are rebuilt in the target CMS. Sanity and Contentful both support multi-state content workflows. User roles and permissions are reconfigured to match your current Drupal access control setup.
