The process
How we migrate from Sanity to Contentful
- 01
Access and gating audit
First we check the existing Sanity and see whether the data is clean enough to move straight over to Contentful, and plan around any auth walls or bot protection in the way.
- 02
Rendering assessment and extraction
Then we work out how Sanity renders its pages and pull the content out, even without CMS access.
- 03
AI-assisted sanitization
Everything extracted runs through our sanitization pipeline, which flags slop, normalizes structure, and leaves us clean content to work with.
- 04
Content-model design with the client
Before anything moves, we agree the Contentful content model with you, shaped around how your editors actually work.
- 05
Transform and soft-migrate
We transform the content to the agreed schema and run a full dry run, so mappings and edge cases prove out before production.
- 06
Execute the real migration
Once the dry run is clean, everything moves into Contentful in one controlled cutover.
- 07
Redirect mapping and throttled sitemap submission
Every old URL gets mapped to its new home with the right redirect, so rankings and link equity survive the move.
- 08
Agentic-browser QA
Finally, automated browsers sweep the new site for data issues, design regressions, and missing SEO signals.

Challenges with Sanity
Key pain points
We obviously prefer Sanity, so much so that our own website is on Sanity. But if you don't have the right implementation team, you might find yourself in a bad situation. Its highly customizable nature can lead to complexity and time-consuming setup processes for less experienced developers. We've inherited our fair share of stinkers, but we advise that before you jump ship, you let us look over it to see if it's salvageable.
That said, if you are considering moving, we can help you migrate away with automated migration scripts, web scraping, and content mapping. It'll be a 1:1 with whatever platform you choose.
Not always plug-and-play
Sanity gives you a ton of flexibility, but it’s not a "drag-and-drop" CMS. If your team prefers instant themes and presets, you’ll need a little extra setup to get started.
Potentially high resource demand
As your content model grows, Sanity gives you incredible power and real-time performance. Just keep in mind that very large projects may require a bit more horsepower behind the scenes.
Less ideal for beginners
Editors love Sanity once everything is set up, but teams switching from traditional CMSs may need a short onboarding period to learn the workflow.
Infrastructure management needed
Unlike hosted CMS platforms, you own your content pipeline. That gives you full control and scalability, but also means setup and environments need to be managed properly.
Technical skill required
Since Sanity is schema-driven, developers can model content precisely the way your business needs it. Non-technical teams benefit from that structure, but setup usually requires engineering support.
Complexity in setup
Sanity doesn’t force rigid templates or assumptions. You have to define everything like content, structure, and workflows. The tradeoff: a bit more initial setup for much more flexibility long-term.
Benefits of Contentful
Key advantages
Contentful is one of the most established headless CMS choices, and we still see plenty of customers land on it after a shortlist.
It's built around structured content, so you model fields once and pull them into any front end you like. That means no copy-pasted components scattered across pages. It also has first-party support for A/B testing and personalization through its Studio add-on, which most competitors don't match natively. The app ecosystem covers SEO, translation, validation, and asset management, and editors get live side-by-side preview for content they're working on.
If your team has the budget and the developer resources to model content properly, it's a solid pick.
API-first design
Contentful was built for APIs from day one, which means your content plugs cleanly into apps, websites, and mobile.
Developer-friendly flexibility
Schemas, content models, and references can be tuned however you like. If your stack is anything beyond "cookie-cutter," Contentful won’t get in your way.
User-friendly interface
Editors enjoy using it. Clean UI, quick search, structured fields, and no "where does this go again?" confusion.
Extensive integration capabilities
Plug in analytics, eCommerce, automation, and translation. Contentful plays nicely with almost anything. And if something isn’t supported yet, you can wire it up yourself without hacking the platform apart.
Scales under traffic
Contentful's global CDN holds up under heavy load. We've run it on sites pushing millions of monthly requests without needing bespoke infrastructure to handle spikes.
Cloud-based architecture
You don't have to install, patch, or maintain anything. It’s fast, globally distributed, and always up to date. Your content team can ship from anywhere without a DevOps babysitter.

Sanity's Free plan includes 20 user seats, 10,000 documents, 1M CDN API requests, 250K regular API requests, 100GB of assets, and unlimited locales. The Growth plan is $15 per seat/month for up to 50 seats, with 25,000 documents and the same API allowances, plus pay-as-you-go overages, private datasets, and 5 roles including Editor, Developer, and Contributor. Enterprise pricing is custom for organisations that need custom roles, dedicated SLAs, or single-tenant infrastructure. Most mid-size teams we work with stay well inside Growth's limits.
The migration is step one. Our Contentful team handles what comes after: builds, integrations and the content model work that keeps the new platform clean.
