For enterprise teams, Sitecore can become harder to justify when content takes too long to publish, routine changes depend heavily on developers, and CMS costs keep rising without a clear improvement in speed or flexibility.
This is why some organizations start looking at Sanity. The move can reduce architectural complexity and give content teams a more flexible way to create and reuse structured content, but it also requires careful planning around cost, SEO, integrations, governance, and cutover.
This guide is for CMOs and IT leaders evaluating a Sitecore to Sanity migration. It explains what the move involves, why enterprises make the switch, how the migration progresses from initial audit through final cutover, what it costs, and how to manage risks and preserve SEO.
What Does Migrating From Sitecore to Sanity Involve?
A Sitecore to Sanity migration involves separating the content from Sitecore-specific structures and presentation logic, remodeling it as structured content in Sanity, and adapting or rebuilding the frontend to consume that content.
This is fundamentally different from moving to Sitecore XM Cloud, now called SitecoreAI CMS. Sitecore’s SaaS CMS remains part of the Sitecore ecosystem and continues to use concepts such as content items, data templates, fields, components, and page layouts. Moving to Sanity means replatforming the content layer rather than modernizing it within Sitecore.
The migration typically follows this sequence:
- Audit the existing Sitecore estate and identify what should move, change, or be retired.
- Design the Sanity content model around the business entities and relationships the organization needs.
- Build repeatable migration tooling to transform and import content and assets.
- Pilot the migration on a representative part of the estate.
- Run both platforms in parallel where necessary while content and integrations are validated.
- Train editors on Sanity Studio, then cut over the frontend and traffic to the Sanity-backed implementation.
- Retire Sitecore only after publishing, analytics, SEO, and integrations are stable.
Sitecore templates and fields provide useful source information, but they should not simply be reproduced one-for-one. Sanity models content through configurable document types, typed fields, and references, all defined in JavaScript or TypeScript schema code. These schemas also shape the editing experience in Sanity Studio, determining which fields editors can use, how those fields are presented, and what validation rules apply. Because the content model is defined in code, developers can version-control schema changes, review them, and deploy updates as part of their development workflow.
Presentation also changes. Sanity stores structured content independently of the frontend, so Sitecore renderings and other presentation behavior generally need to be mapped to components in the new frontend implementation. Sanity can then connect that frontend back to Studio for live preview and visual editing through its Presentation tooling.
For a large enterprise estate, the work spans content architecture, migration engineering, frontend implementation, integrations, governance, SEO, and cutover planning rather than a simple CMS export and import. The biggest risks are losing SEO equity and recreating Sitecore’s complexity inside the new content model, which is why many enterprises run the migration with a partner experienced in both Sitecore and Sanity, such as Multidots.
Why Do Enterprises Move From Sitecore to Sanity?
Enterprises typically consider moving from Sitecore to Sanity to reduce CMS overhead, improve content operations, and adopt a more flexible headless architecture. The exact cost benefit depends on the existing Sitecore contract, traffic, team size, and implementation, but the broader goal is usually to simplify how content is managed and delivered.
For content teams, the biggest change is moving toward structured, reusable content. Sanity stores content independently of a particular page or presentation, so the same product information, article, campaign asset, or other content object can be referenced and reused across websites, apps, and other digital experiences.
Sanity Studio also provides a customizable editing environment with real-time collaboration. In Sitecore’s traditional Content Editor, editors navigate a hierarchical tree of content items to find and update their fields, and the Experience Editor (Pages in SitecoreAI) adds on-page editing, which Sanity covers with its Presentation tool. Sanity Studio, by contrast, lets teams customize how documents are organized and presented, grouping content by type, campaign, or editorial workflow. This makes it easier for editors to find and manage reusable content based on how their teams work rather than where an item sits in a predefined hierarchy.
For development teams, headless delivery creates a cleaner separation between the CMS and frontend. The frontend can use frameworks such as Next.js while Sanity supplies structured content through APIs, giving engineering teams more control over rendering, deployment, and performance optimization. A headless rebuild does not automatically make a site faster, but it gives teams more freedom to optimize the delivery layer independently.
Cost can also influence the decision; the cost section below compares how the two pricing models work.

How Do You Migrate From Sitecore to Sanity?
A Sitecore to Sanity migration works best as a phased replatform rather than a one-time content export. The goal is to keep the existing experience running while the new content model, frontend, integrations, and editorial workflows are built and validated.
That approach protects three things that matter to the business: site availability, SEO equity, and editorial continuity. Sanity itself recommends repeatable migration tooling and incremental migration so teams can keep source content current and reduce the pressure around final cutover.
For planning purposes, Multidots’ 2026 migration matrix classifies migrations from both Sitecore On-Prem and Sitecore XM Cloud to Sanity as high complexity, with an estimated timeline of 20–32 weeks. This estimate assumes a mid-sized implementation with 10,000–50,000 content items, 5–10 content types, and standard integrations. For enterprise-scale estates, the matrix adds 30–50% to that timeline. Where a project lands in that range depends on the complexity of the existing content, integrations, frontend rebuild, governance requirements, and localization.
Before migrating content, teams also need to translate Sitecore concepts into a Sanity architecture:
| Sitecore concept | Sanity approach | What this means for your team |
|---|---|---|
| Data templates | Schema and document types | Use the existing templates as source material, but redesign types around reusable business entities rather than copying every Sitecore template. |
| Template fields | Typed schema fields | Map useful fields to Sanity types such as strings, numbers, images, references, arrays, objects, and Portable Text. |
| Rich Text fields | Portable Text | Convert HTML-based rich text into structured Portable Text blocks, mapping formatting, links, embedded media, and custom elements while validating the results. |
| Content-tree items and hierarchy | Documents and references | Preserve relationships deliberately instead of reproducing the Sitecore tree simply because it existed. |
| Renderings and presentation details | Frontend components | Reimplement presentation behavior in the frontend and connect components to structured Sanity content. |
| Media library | Sanity assets, Sanity Media Library (an Enterprise add-on), or an external DAM | Decide where enterprise assets should live, then migrate files, metadata, and references accordingly. |
| Language versions | Field-level or document-level localization | Decide whether translations belong in shared documents or separate language-specific documents, then migrate localized content while preserving translation relationships and language-specific publishing requirements. |
The goal isn’t to recreate Sitecore inside Sanity, but to preserve what works, redesign what doesn’t, and avoid carrying legacy complexity into the new platform.
Audit the Sitecore Estate
Start by inventorying the templates, fields, content items, renderings, media, languages, workflows, personalization rules, URLs, and external integrations that make up the current estate.
Then classify each element as migrate, remodel, rebuild, or retire. Moving everything automatically is usually the wrong goal. Sanity specifically recommends using a replatform to clean up obsolete, inconsistent, or presentation-bound content rather than carrying legacy structure into the new system.
This audit becomes the source of truth for schema design, migration scripts, frontend scope, redirects, and QA.
Extract and Transform the Content
Next, build migration tooling that can extract Sitecore content and transform it into the new Sanity schema.
That typically means mapping fields, reconstructing references, migrating assets, normalizing inconsistent values, and converting suitable rich-text content into Portable Text. Portable Text stores rich content as structured JSON rather than tying it to HTML markup, which makes the same content easier to render across different frontends.
The migration scripts should also be repeatable. Sanity recommends idempotent migration processes that can be rerun against current source data, which reduces the need for a long content freeze before launch.
Run a Pilot and Validate the Migration
Before moving the full estate, migrate a representative but lower-risk section.
The pilot should test more than whether text appeared in Sanity. Use automated reconciliation scripts to compare migrated content against the agreed source-to-target mappings, checking for missing records, broken references, incomplete assets, and discrepancies in required fields or language versions. Alongside these automated checks, validate metadata, redirects, frontend rendering, integrations, permissions, and how editors actually create and update content in Studio.
This is where teams find schema decisions that looked sensible on paper but become awkward in real editorial use. Correcting them at pilot scale is considerably safer than remodeling thousands of documents later.
Run Sitecore and Sanity in Parallel
Where the publishing schedule requires it, keep Sitecore live while the Sanity implementation is being validated.
Editors can continue working in the existing platform while migration tooling is rerun to bring newer content across. The team then reconciles changes made during the migration window before the final switch.
Cut Over to Sanity and Retire Sitecore
The final cutover should happen only after the content, frontend, integrations, redirects, analytics, and editorial workflows have passed production-level QA, and editors have been trained on the new Studio workflows.
Run the final content sync, activate the prepared URL mappings and 301 redirects, deploy the Sanity-backed frontend, and verify critical journeys immediately after launch.
Sitecore should be retired after, not during, that transition. Monitor search traffic, indexing, analytics, forms, integrations, publishing, and content accuracy long enough to confirm the new platform is operating as expected before shutting the old environment down.
What Does a Sitecore to Sanity Migration Cost?
Sanity Growth costs $15 per seat per month, Sanity Enterprise uses custom pricing, and Sitecore pricing is defined in each customer’s contract. The one-time cost of migrating from Sitecore to Sanity is separate and varies with the size and complexity of the estate.
Sitecore uses contract-based pricing rather than publishing a standard enterprise list price. Sitecore states that each customer’s Order defines the products and services purchased, pricing, subscription terms, and applicable entitlements.
Sanity Growth supports up to 50 user seats, five permission roles, and two private or public datasets, with pay-as-you-go pricing available for higher usage. Enterprise supports a custom number of seats, roles, datasets, and usage quotas.
| Pricing consideration | Sitecore | Sanity |
|---|---|---|
| Pricing model | Pricing is defined in the enterprise Order rather than on a public price list. | Growth is $15 per seat per month, with usage quotas and applicable overages. |
| Enterprise terms | Commercial scope depends on the Sitecore products, services, subscription terms, and entitlements purchased. | Enterprise uses custom pricing and custom usage quotas. |
| Cost drivers | Existing organizations need to review their own contract to establish the current platform cost. | Cost depends on factors such as seats, datasets, documents, API usage, assets, bandwidth, and enterprise requirements. |
The CMS subscription is only part of the migration budget. Enterprises should also account for content-model design, migration tooling, frontend work, integrations, asset migration, SEO preservation, testing, editor training, and the period when Sitecore and Sanity run in parallel.
A large frontend rebuild or heavily customized Sitecore estate can cost considerably more to migrate than a content-heavy site with a relatively clean headless frontend. Conversely, retiring obsolete templates, integrations, and content during the migration can reduce the amount of legacy complexity that needs to be rebuilt.
For a useful budget, scope the actual estate rather than applying a generic per-page migration rate. Multidots offers enterprise Sanity migration services covering content architecture, migration, integrations, implementation, and launch planning.
What Are the Main Sitecore to Sanity Migration Risks?
The main risks in a Sitecore to Sanity migration are losing SEO equity, carrying Sitecore’s legacy complexity into the new content model, and overlooking capabilities such as personalization, integrations, governance, or localization during the rebuild. An audit-first, phased migration gives teams a way to identify and test each of these before cutover.
| Migration risk | Control |
|---|---|
| SEO loss | Inventory existing URLs, preserve metadata and structured data, create 301 redirects, and test links before launch. |
| Content-model mismatch | Model business entities and relationships first instead of recreating Sitecore templates and page structures one-for-one. |
| Lost personalization | Inventory existing personalization and experimentation logic, then decide what should be rebuilt, redesigned, or moved to another service. |
| Integration failures | Map every integration, API, webhook, search service, form, analytics tool, and downstream dependency during discovery. |
| Poor data quality | Validate, normalize, and deduplicate source content as part of the transformation process. |
| Low author adoption | Involve editors during schema and Studio design, test real workflows, and provide training before cutover. |
The most important content-model risk is a lift-and-shift migration. Sanity advises against simply reproducing a legacy CMS’s page-oriented structure. Instead, content should be remodeled around what it represents, such as a product, person, location, or article, with references connecting reusable documents.
SEO requires its own migration workstream. Changing the CMS or frontend can alter URLs, internal links, metadata, structured data, and rendered HTML. The section below on preserving SEO during migration explains how to manage these changes and protect search visibility throughout the transition.
Personalization and integrations also need to be treated as separate capabilities rather than assumed to migrate with the content. Sitecore Personalize, for example, can use behavioral and transactional data to run experiments and personalized experiences. If the existing estate uses those capabilities, the migration team needs to inventory the underlying use cases and determine how each will work in the target architecture.
For regulated or globally distributed enterprises:
- Design governance before editors move.
- Define roles and publishing permissions, approval processes, localization structure, and audit requirements alongside the content model.
Sanity supports role-based access controls and localization on every plan, and its Enterprise plan adds custom roles, Content Releases for coordinating and validating groups of changes, and a full audit trail.
How Do You Preserve SEO During the Migration?
To preserve SEO during a Sitecore to Sanity migration, inventory existing URLs, map every URL that changes to its most relevant destination, implement permanent redirects, carry critical SEO data into the new frontend, and monitor crawling and traffic through cutover.
Start with a full crawl of the Sitecore site. The migration team should record indexable URLs along with titles, meta descriptions, canonicals, headings, structured data, hreflang annotations where applicable, internal links, and current indexation.
For URLs that change, build a one-to-one redirect map wherever possible. Google recommends server-side permanent redirects such as 301 or 308, pointing old URLs directly to their new destinations rather than creating redirect chains or sending unrelated pages to the homepage. Google also recommends keeping redirects in place for at least a year, and notes that permanent redirects do not cause a loss of PageRank.
The new Sanity-backed frontend should also preserve or deliberately improve:
- Page titles and meta descriptions.
- Canonical URLs.
- Structured data.
- Hreflang annotations.
- Crawlable internal links.
- XML sitemaps.
- Robots directives and indexability.
The pilot and parallel-run phases make this safer. Teams can crawl a migrated section, compare its rendered HTML with Sitecore, test redirects and structured data, and correct systemic problems before the full cutover.
After launch, monitor Google Search Console, analytics, server logs, 404s, redirect errors, indexing, and organic landing-page traffic. Temporary ranking fluctuations can occur during a substantial site move while Google recrawls and processes the new URLs.

Plan Your Sitecore to Sanity Migration With Multidots
A successful Sitecore to Sanity migration requires both Sitecore migration experience and a strong understanding of how Sanity should be modeled and implemented. Building entirely in-house can make sense when your team already has that combination. Otherwise, an experienced migration partner can reduce the amount of architecture, tooling, testing, and cutover work the internal team has to develop from scratch.
When evaluating a partner, look for five things:
- Relevant migration experience: Evidence of large, complex CMS replatforming projects.
- A documented methodology: Clear phases for discovery, modeling, migration, validation, parallel operation, and cutover.
- Repeatable migration tooling: Scripts and processes that can be rerun as content changes before launch.
- An SEO-preservation plan: URL mapping, redirects, metadata migration, QA, and post-launch monitoring should be part of the project rather than an afterthought.
- Post-launch support: The team should remain involved while editors, integrations, analytics, and the new frontend settle into production.
Multidots is an official Sanity agency partner with 22 Sanity-certified engineers, providing Sanity strategy, content modeling, development, migration, integrations, and ongoing support.
Multidots has delivered more than 1,000 CMS migrations, giving it experience with the operational challenges involved in moving large enterprise estates between platforms. For one global automotive manufacturer, Multidots migrated 20 websites, 20 archive sites, and more than 20,000 media assets from Sitecore to WordPress in 22 weeks, while maintaining integrations and governance requirements. The new platform cut total cost of ownership by 35% and gave editorial teams greater independence from developers.
For enterprises migrating to Sanity, that same focus on editorial independence can be supported through Sanity Studio’s tools. The Presentation tool enables live previews and click-to-edit functionality when integrated with the frontend, while comments and tasks help editors coordinate content reviews directly within Studio.
Multidots can handle the migration to Sanity as one connected program rather than treating content export, Sanity implementation, frontend work, SEO, and launch as separate projects.
