The process
How we migrate from Joomla to Sanity
- 01
Access and gating audit
First we check the existing Joomla 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 Joomla 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 Joomla
Key pain points
Joomla sits in the same bracket as WordPress, except it is somehow even harder to explain to anyone under 40. If your C-suite still thinks "PHP developer" is a personality type, Joomla will make them feel right at home. You will also keep your hosting provider happy, because nothing about this platform is light or low-maintenance.
The dev experience feels stuck in a pre-Composer, pre-type-hints era. Major upgrades are the real horror story. Joomla 3 and 4 both went end of life in October 2025, and moving up a major version tends to break extensions and templates badly enough that you rebuild the site anyway. The community is smaller than WordPress's, the documentation is hit-and-miss, and the admin panel feels like a government portal that accidentally became a CMS. Performance on shared hosting is shaky and the editing workflow is clunky. If you really, truly still want Joomla, we will point you to another agency, or sit down with us for half an hour and we will talk you out of your biggest digital regret.
Steep learning curve
Joomla makes even simple tasks feel like you’re onboarding into a new corporate ERP system. If you’re not already fluent in its quirks, prepare to lose a weekend (or three).
Outdated coding standards
Still clinging to older PHP conventions, missing modern practices, and generally stuck in a time capsule. If you enjoy fighting your own tools, you’ll love it.
Complex migration process
Upgrading versions feels less like an update and more like a full-blown rebuild. Random extensions break, templates combust, and you’re left questioning your career choices.
Extension compatibility issues
Half the ecosystem works… depending on your version, your template, the time of day, and whether Mercury is in retrograde. Reliability is not its strong suit.
Limited template selection
Unless you’re aiming for "government website from 2011," the design ecosystem doesn’t give you much to work with.
Interface complexity barriers
The admin panel still feels like an escape room puzzle. Everything is technically there, but actually finding or using it is another story.
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
Joomla to Sanity migration FAQs
Answers to the most common questions about Joomla to Sanity migration
Yes. Joomla is open-source software under the GPL, so there is no licence fee and you can download Joomla 6 and self-host it for nothing. The real cost is everything around it. You pay for hosting, for any commercial extensions and templates you bring in, and for the developer time that keeps it patched and upgraded. Treat the price tag as hosting plus extensions plus maintenance, not a SaaS subscription. On a busy site those running costs add up fast, which is the part most "Joomla is free" claims quietly skip.
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.
