From Payload to Sanity

The process
How we migrate from Payload to Sanity
- 01
Access and gating audit
First we check the existing Payload and see whether the data is clean enough to move straight over to Sanity, and plan around any auth walls or bot protection in the way.
- 02
Rendering assessment and extraction
Then we work out how Payload 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 Sanity 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 Sanity 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 Payload
Key pain points
Payload’s biggest issue is how quickly it hands you the responsibility baton. Because it leans so heavily on self-hosting, you’re suddenly running databases, managing infra, dealing with scaling, and debugging auth quirks at 11 pm. And since the platform is still maturing, updates can feel unpredictable, and the surrounding ecosystem isn’t quite deep enough yet to soften the landing when something breaks. The recent Figma acquisition didn’t help either. Support has felt a bit lighter, and some priorities clearly shifted, alongside pricing.
Payload feels flexible on day one, the moment your project grows you’re either engineering around gaps or paying more than expected. If you're debating whether Payload fits the future of your stack (or you’re already feeling the cracks), we’re always happy to help you plan a cleaner path or a migration that won’t come back to bite you.
Steep learning curve
Payload’s code-first approach means you need solid dev experience to use it effectively. Non-technical teams will struggle, and onboarding takes longer compared to more guided CMSs.
Smaller ecosystem of plugins
There aren’t many ready-made extensions, so you’ll end up building features yourself. This adds development time and increases long-term maintenance.
Potential performance overhead
Because it’s a full JavaScript backend, Payload can get resource-heavy under high traffic. You’ll need to optimise your server setup and monitor performance more closely.
Gaps in documentation
The docs are improving, but there are still missing pieces and unclear sections. New users often have to dig through GitHub issues to find answers.
Small community
The community is growing but still small, so there’s less shared knowledge, fewer tutorials, and slower troubleshooting compared to bigger CMS ecosystems.
Requires separate hosting
Payload doesn’t come with built-in hosting, so you’re responsible for setting up and managing your server. That adds extra cost, extra setup, and extra operational overhead.
Benefits of Sanity
Key advantages
You know where our bias' lies. We think Sanity is literally the best headless content management out there. The schema is code-based, so it can be easily versioned, scaled, and extended without a heap of third-party hoops to jump. Providing you build it with a solid foundation, which we always recommend Turbo Start Sanity, it's going to be the most valuable hub for content you can imagine.
It's got a very unique tooling called the Live Content API, which in simple terms means
when you press publish, its live.
No issues with caching, and a single API usage that scales perfectly with multichannel content delivery.
It also offers one of the best editorial experiences in the industry with Presentation and customizable content structures. We're obviously huge fans of it, and we've pivoted our business with it when we realised how ahead it is.
Real time collaboration
You write, your teammate tags in, adds citations, and updates the same doc without stepping on each other. It’s the fastest way to ship content without the "who has edit access?" chaos.
Live preview block building
With Sanity, you don’t have to guess what your page might look like. Real-time previews update the moment you type. It’s a 1:1 mirror of your site before it ever goes live, so your campaigns look right the first time.
Meta tags, structured content
Sanity’s structured content gives Google clean data and rich schema, so your pages surface higher without manual hacking. Automated schema, smarter metadata, and better rankings.
Better media management
A blazing-fast media library with first-class support for Cloudinary, Mux, Wistia and more. Upload, drag-and-drop, preview without wrestling with assets, and waiting for spins of doom.
Automated social sharing
Ever wanted to share one update, and automatically populate every social platform? Welcome to the future we've built that. Why should social media be a chore.
Automated image generation
Sanity keeps your subject centred and sharp like a tiny author thumbnail or a full-page hero banner. There are no awkward crops, or chopped heads. Your visuals just look right everywhere.
Common questions
Payload to Sanity migration FAQs
Answers to the most common questions about Payload to Sanity migration
Payload stores content in MongoDB or Postgres, so extracting your data is straightforward compared to proprietary platforms. The real work is restructuring your content model for the target CMS and rebuilding any custom access control logic you've written. We typically complete Payload migrations in 3 to 6 weeks depending on how much custom backend logic is involved. The code-first nature of Payload means most of the content model is well-documented in your own codebase, which actually makes migration planning easier.
The migration is step one. Our Sanity team handles what comes after: builds, integrations and the content model work that keeps the new platform clean.
