Sanity works well for growing content teams, until the trade-offs start to get in the way. More editors mean higher per-seat costs, document limits can affect how you manage content, and marketing may want more control over page layouts without relying on developers. For some companies, it also comes down to having more ownership and control over their content platform.

Moving from Sanity to WordPress can solve some of these issues, but it’s not as simple as exporting content and importing it into WordPress. You need to map your content, rebuild the right structures, protect SEO, and plan the cutover carefully.

In this guide, we’ll see what a Sanity-to-WordPress migration requires, what to assess before you start, how to prepare WordPress, migrate and test your content, protect your search traffic, and get through launch without disruption.

We’re rtCamp, an engineering company and WordPress VIP Premier Partner with 500+ enterprise WordPress projects. This guide is based on our experience and focuses on the decisions and practical steps that matter most for a successful migration.

TL;DR

Why companies migrate from Sanity to WordPress

A fair business case starts with what Sanity does well, so let’s start there to see what to expect from WordPress in terms of these capabilities.

Sanity’s real-time collaboration lets several editors work in the same document at once, GROQ gives developers a flexible query language across the whole dataset, and schemas are in code alongside the rest of the project. The free tier is generous, and the Growth plan starts at a low per-seat price. For each of these capabilities, your team will need an equivalent in WordPress, so list the ones you use during discovery.

The case for moving usually rests on the fact that Sanity charges per seat and meters usage on top. 3 limits tend to force the decision to migrate:

We call the cumulative effect the Platform Tax, which includes the seat fees, add-ons, overages, and engineering time that come with staying on a vendor-controlled platform. 

The Platform Tax: 100% of what you're charged minus the 40% your team uses equals a 60% Platform Tax

WordPress changes that equation because it is open-source infrastructure with no license, per-seat, or per-document fees. You only pay for 3 aspects:

That spend should be modelled honestly. In return, you get:

✅ Ownership of the codebase and data

✅ A block editor that lets marketing build pages from governed components without developer tickets

✅ REST and WPGraphQL APIs for headless delivery

✅ The ecosystem behind 43% of the web

✅ Enterprise hosting with SOC 2 compliance and 24/7 monitoring on WordPress VIP

We describe this shift as From CMS → To Infrastructure.

Staying on Sanity is often the better choice for small, developer-led teams that sit comfortably inside the Growth quotas, rely heavily on live co-editing, or use Sanity mainly to feed non-web channels. Our Sanity vs WordPress guide compares the platforms in more depth. 

If the case holds up, the next step for your successful migration is understanding how long it usually takes.

How long does it take to migrate from Sanity to WordPress?

There’s no unified timeline for a Sanity-to-WordPress migration because every setup has a different level of complexity. Based on our experience, these are typical ranges:

Migration profileTypical durationSingle site, low integration complexity2–4 monthsMid-complexity: CRM, analytics, and workflow rebuilds3–5 monthsMulti-brand or multisite enterprise4–8 months

The biggest factors are the number of document types and custom Portable Text objects, integrations, frontend approach, how many locales you support, and how much content needs to be cleaned up before migration. In a mid-complexity migration, these workstreams usually overlap. Backend design starts around week two while the migration scripts are being built alongside it. The full content migration starts once the required WordPress structures are ready.

The reference plan below follows rtCamp’s Delivery Model: Audit → Pilot → Phased Build → Enablement → Hypercare → Evolution.

Tips on planning and assessing migration

The assessment confirms the frontend approach and creates inventories for content, SEO, backend functionality, and AI-readiness. Together, these become your migration blueprint.

This step is also what makes the timeline realistic. Most migration estimates go wrong because of aspects that weren’t identified early enough.

Start with the frontend

Before going deep into the rest of the assessment, decide which frontend path you’re taking. It affects what you need to rebuild, what you can keep, and which parts of the current setup need a closer look.

Once the frontend path is clear, you can start mapping the content and SEO that sit behind it.

Assess content and SEO

This is where you find out exactly what you have, what is worth moving, and what could cause problems after launch.

Content inventory. Build the inventory from the Sanity dataset itself rather than relying on what editors remember. Count documents by type, separate published, draft, and release versions, and record which fields each type uses. Sanity schemas often contain fields that are rarely populated, so the dataset gives you a much more accurate picture. The inventory script in the pre-migration section can do this in a few seconds.

Content quality. Give each content group a clear destination: migrate, merge, rewrite, redirect, or retire. Doing this before migration can remove a meaningful amount of unnecessary work from the project.

URL inventory. This is one of the areas where Sanity migrations can easily go wrong. Sanity stores content and slugs, but the actual URLs are usually created by the frontend’s routing code, such as /blog/[slug]. That means you need to combine several sources to build a complete URL inventory:

  1. A full crawl of the live site.
  2. Your XML sitemaps.
  3. The frontend’s route definitions.
  4. Google Search Console and your backlink tool, including URLs that have generated traffic or backlinks in the past 12 months but are no longer linked internally.

Metadata and structured data. Document where every SEO element comes from in the current setup. Titles, descriptions, and Open Graph fields often live in a custom seo object in the Sanity schema. Canonical tags, hreflang, and JSON-LD such as Article, Organization, BreadcrumbList, FAQPage, and Product are often generated by frontend code instead, so they won’t be part of the Sanity export. Capture them from the rendered pages.

Baselines. Record organic traffic and rankings by template and for your most important pages, along with crawl statistics, indexed page counts, Core Web Vitals, and the internal link structure. These become your reference points when you check the site after launch.

With the content and SEO picture in place, the next step is to understand everything the Sanity backend currently does beyond storing content.

Review the backend

The backend assessment is about finding the functionality that has to be rebuilt, replaced, or deliberately left behind.

Review the schema. Go through the Studio schema files, including every document type, object type, field, validation rule, and reference. These files are usually the most accurate specification of how your Sanity content model actually works.

Inventory functionality. Document the Sanity features your team relies on, including:

Map integrations and workflows. For every integration, record where the data goes, what triggers the integration (webhook, scheduled job, or on-demand API call), how it authenticates, and who owns it. Do the same for editorial workflows: document the steps, roles, and notifications involved.

Simple process maps are useful here. They make missing steps and unclear ownership much easier to spot before UAT.

Assess AI-readiness before migration

AI-readiness is worth assessing as part of the migration. The content model, APIs, and governance decisions you make now will determine what AI can do with the platform afterwards.

Sanity already has its own AI capabilities, including AI Assist and agent features, so this may be functionality your team is already using. WordPress 7.0, released on May 20, 2026, also introduced AI foundations into core: an AI Client that allows plugins to send prompts to an AI provider connected by the site owner,  and a Connectors screen for managing providers. 

rtCamp has released 3 open-source connectors for the WordPress AI Client: for OpenRouter, LM Studio, and the Universal OpenAI API Connector.

We assess AI-readiness with The 5 AI Dimensions Framework, which looks at five areas:

The priorities you set here go straight into the migration blueprint, so AI planning should be part of the migration.

Turn the assessment into a migration blueprint

By the end of the assessment, you should have the frontend approach, target content model, mapping rules, integrations, redirect strategy, AI-readiness requirements, and a timeline based on what the team found covered. Combined, you can build a migration blueprint for your team to follow.

With that blueprint agreed, you can move on to preparing the WordPress environment and the content itself.

Let’s look at the migration process in more detail. 

How to migrate frontend, backend, and content

A Sanity-to-WordPress migration has 3 main workstreams that include frontend, backend, and content. The backend defines the content model, the content fills it, and the frontend renders it. 

We start with the frontend because it shapes the other two layers. Sanity is headless, so what happens to your existing frontend determines 3 things:

Frontend migration

Most enterprise sites don’t need a headless architecture, and a well-governed block editor gives marketing more independence than a decoupled one. For Sanity teams, the trade-off looks like this:

Decide per property, based on who changes pages, how often, and what the frontend does beyond rendering content. rtCamp has delivered both patterns, including OpenWeb‘s decoupled WordPress backend with a Gatsby and React frontend.

Keeping your frontend

If WordPress only serves content through its APIs, there’s no theme to build. The work covers 6 areas:

  1. Data fetching. Rewrite each GROQ query as a WPGraphQL query (or REST call) that returns the same shape. GROQ’s -> joins become nested fields.

  2. Rich content. Choose how post content reaches the page:

    • Render the post’s HTML with WordPress’s block library styles.
    • Or query structured blocks through WPGraphQL Content Blocks and map each block to a component.

  3. Preview. Sanity’s Visual Editing doesn’t carry over, so build a preview route that makes authenticated requests to WordPress, using application passwords or JWT.

  4. Revalidation. Replace GROQ-powered webhooks with WordPress hooks that call your frontend’s on-demand revalidation endpoint.

  5. Images. Sanity handles crops and hotspots through URL parameters, while WordPress generates registered image sizes and srcset. If your design relies on hotspots, carry the values over as metadata or add an image CDN.

  6. Routing. The frontend often handles redirects, sitemaps, and robots.txt today. Decide which system takes over each one after launch.

Moving the frontend into WordPress

On this path, the separate app is retired and your design is rebuilt as a block theme:

  1. Choose a starting point. Adapting an existing block theme from the WordPress directory is faster. For enterprise sites we recommend a custom theme built from your design system, because it gives you governed components and clean markup.

  2. Audit components. List every section, module, and component, including those driven by Portable Text custom types.

  3. Map them to WordPress.

    • Simple components become patterns.
    • Components with custom behaviour become custom blocks.
    • Page layouts become templates.

  4. Move design tokens (colours, typography, spacing, and widths) into theme.json as global styles.

  5. Rebuild interactive features such as carousels, filters, and search as custom blocks, using the Interactivity API for front-end behaviour.

  6. Baseline Core Web Vitals on the current site and treat them as acceptance criteria for the rebuild.

SnapWP: a path between the two

SnapWP is rtCamp’s open-source framework for headless WordPress, built on WPGraphQL and WPGraphQL Content Blocks.

It renders your WordPress block theme on a Next.js frontend, so you get a working headless site immediately without rebuilding every template as a component. It suits Sanity teams who want to keep a JavaScript frontend and give editors control of layout. Discover more about SnapWP in this article.

Backend migration

Whichever frontend path you choose, it reads from the same content engine. The backend workstream builds that engine in WordPress, and it has five parts.

1. Content model. Your Sanity Studio schema files are the specification, and they map to WordPress like this:

Register post types, taxonomies, and meta in code (register_post_type, register_taxonomy, and register_post_meta with show_in_rest enabled so the APIs expose them). Use a field framework such as Secure Custom Fields or ACF where editors need a field UI.

2. Roles and editorial workflow. Map Sanity’s roles to WordPress roles and capabilities, and write down every approval step your team uses today.

3. Integrations. List every system that reads from or writes to Sanity. These include CRMs, ERPs, marketing automation, search indexes, DAMs, translation services, analytics, and any Sanity Functions or webhook consumers. For each one, decide how it will be rebuilt and where its credentials will be stored. The options are:

A CRM connection, for example, usually becomes a CRM plugin or a small custom integration. Plan for data consistency during the transition, too. While both platforms are live, some systems may need scheduled synchronization, middleware, or custom scripts for edge cases, so they don’t read stale or conflicting data.

4. Localization and personalization. Sanity projects handle translation at either the document level or the field level. WordPress handles it with a multilingual plugin (WPML or Polylang) or a multisite network with one site per locale. The right choice depends on whether translations share structure and whether locales publish independently. If your Sanity setup drives personalized experiences, usually through the frontend or a third-party tool, decide which system will handle that logic and hold its audience data after the move.

5. Platform and API layer. Install WordPress on hosting sized for your scalability, security, and performance needs, then configure it for how the content will be consumed.

Next, test each rebuilt feature in staging against the Sanity behaviour it replaces, checking API responses, workflow automations, and integration points. Based on what that testing shows, tune the configuration for performance, security, and reliability. Once the backend passes these checks, it’s ready to receive content.

Content migration

Once the backend structures are in place, the content workstream fills them. It moves documents, rich text, references, media, and metadata from Sanity into WordPress, preserving relationships and SEO value. The process is built to run repeatedly until the output is right, and it follows an extract, transform, load, and verify loop.

Extract. Export the dataset with the Sanity CLI. It produces a gzipped tarball containing data.ndjson (every document, one per line), assets.json, and folders of image and file binaries. For smaller migrations, or when you want references resolved at query time, you can extract with GROQ queries through @sanity/client instead. Another option is Sanity’s Export API, which streams documents without the asset binaries.

Transform. Map each Sanity document to its WordPress equivalent (a post, page, or custom post type) and convert it into the shape WordPress expects:

The result is a clean, transformed data file that the importer reads.

Load. Start with a fresh WordPress install that already has the content model in place, so no leftover data interferes. Install and activate the importer plugin. rtCamp uses its own Sanity to WordPress Migration plugin, which automates most of the work of transferring content and media.

WordPress Plugins screen with the Sanity to WordPress Migration plugin installed.

Then open your command line and run the import through WP-CLI. This is the fastest option because it runs on the server:


			wp sanity-to-wp import --source=cleanData.json

Replace cleanData.json with the path to your transformed file. If the importer has to run somewhere other than the server, the REST API is the alternative. The command reads the transformed data and creates posts, pages, and custom post types. It also sets metadata and preserves the relationships defined in your mapping. Every write is an upsert keyed on the Sanity document ID, so re-running the import updates content instead of duplicating it.

Media. The importer handles media before the documents that use it:

  1. It downloads the images, videos, and other files your content references from Sanity.
  2. It uploads each one to the WordPress Media Library once, with alt text and captions carried over.
  3. It updates every reference and URL in the content to point at the new media locations, so embedded media, files, and internal links keep working.

Verify. Check counts per content type, spot-check rendered pages against the live site, and confirm every image resolved. Compare the new URLs against the redirect map, and set up 301 redirects for any that changed. Then open a sample of posts in the block editor to confirm the markup validates.

Here’s how to install and activate the Sanity to WordPress Migration plugin and run the import command to transfer blog content.

Sanity_migration-to-wp

Once the import passes verification, you have a WordPress site populated with your Sanity content, ready for full testing.

Launch your new site

By launch day, most of the hard work should already be behind you. The goal now is to make the switch predictable, so prepare everything in advance, move traffic in a controlled way, and keep a tested rollback option in case something goes wrong.

Pre-launch preparations

A few final checks can save a lot of trouble after the switch.

Once these checks are done, the actual switch should be fairly uneventful.

Go-live procedure

rtCamp uses a blue-green deployment approach for migrations. Once the new platform is built and tested alongside the live site, the existing environment stays available until the new one is confirmed. The final switch happens at the DNS level, which also gives you a straightforward rollback path.

  1. Final staging review. Run through the critical workflows one more time, including forms, sign-ups, purchases, and search. Remove placeholder content and make sure staging-only settings, such as noindex, cannot reach production.
  2. Switch. Update DNS or, for a headless setup that keeps its existing frontend, switch the frontend to the new WordPress data source. Then confirm that traffic is reaching the new platform.
  3. Verify the live site. Run the redirect crawl again, submit the new sitemaps, and check analytics, tag firing, and server error logs.
  4. Monitor. Keep a close eye on traffic, errors, and performance during the first 24 hours. Once the site is stable, move into hypercare.

Rollback plan

You may never need to roll back, but you should know how to do it before launch.

For high-traffic sites, you can reduce the risk with a phased cutover. For example, you could route /blog/* to the new WordPress-backed pages while the rest of the site continues running on Sanity. 

Once that section passes its checks, move to the next one.

Post-migration checklist

The migration doesn’t really end when DNS changes. The first few weeks are about making sure the content, SEO, performance, and editorial workflows all survived the migration and helping the team get comfortable with the new setup.

Content validation

Start with the things users and editors are most likely to notice.

Once the content is in good shape, keep an eye on the technical side too.

Performance monitoring

Use the pre-migration baseline to see whether the new setup is holding up in real-world use.

Security and maintenance

WordPress needs regular maintenance, especially as the number of plugins and integrations grows.

Helping the team get comfortable

A new CMS can be technically sound and still create friction if editors aren’t comfortable using it.

Hypercare and what comes next

The first 30 days after launch are typically the hypercare period: close monitoring, quick fixes, and regular SEO checks against the pre-migration baseline.

After that, the site moves into the next phase, and ongoing improvements, new features, content model changes, and platform upgrades take place. Your team can handle this internally, rtCamp can support it, or both teams can work together.

FAQ

How long does a Sanity-to-WordPress migration take?

A single site with light integrations typically takes two to four months. Migrations that include CRM, analytics, and workflow rebuilds usually take three to five months, while multi-brand or multisite programmes can take four to eight months. For a more specific timeline, feel free to contact our team. 

Can we keep our Next.js frontend?

Yes. WordPress can run headless and serve content through WPGraphQL or the REST API. In that setup, the main frontend work is adapting data fetching, preview, revalidation, and image handling to WordPress.

If you want to keep a headless frontend but give editors more control over layouts, SnapWP can render WordPress block themes on a Next.js frontend.

What happens to Portable Text?

Portable Text is converted into Gutenberg block markup using a migration script with explicit rules for each block style, mark, and custom object. Custom objects can become custom WordPress blocks. The resulting markup is then validated in the block editor so editors get clean content.

Will we lose search rankings?

A migration doesn’t mean losing search visibility. The main safeguards are keeping existing URLs where possible, creating a complete one-to-one redirect map from a live-site crawl, mapping metadata field by field, preserving server-rendered structured data, and monitoring the site after launch.

Some temporary fluctuation can happen after a migration. If traffic or rankings stay down, the cause is often something concrete, such as a missing redirect, changed URL, or missing metadata.

Do we need to freeze content during the migration?

Only for a short period. Editors can keep publishing in Sanity while the migration is being prepared. Just before cutover, you pause publishing and run a final delta import, which moves only the documents changed since the previous migration run. When rtCamp migrated Videojet from AEM CQ5 to WordPress VIP, we moved 28 websites, 12,000+ pages, and 22 languages with zero marketing downtime.
