Migrate Sitecore to Sanity CMS
Your Sitecore License Renews in 90 Days — Unless You Kill It First
Why leave Sitecore?
- Pay $100K–$500K annually for Sitecore licenses while hiring scarce C# developers at premium rates
- Lock your business into Content Hub's tightly coupled modules that deepen vendor dependency yearly
- Watch editors reload fragile Experience Editor previews that break on layout changes or JSS version drift
- Block content reuse across channels with rigid page templates requiring developer intervention for components
- Fund enterprise xDB personalization infrastructure your team never configures beyond basic A/B tests
- Maintain on-premise infrastructure or wrestle XM Cloud's opinionated deployment constraints and surprise overages
What you gain
- Define content schemas in TypeScript with Git history — audit every field change and port models between projects
- Edit content simultaneously with your team seeing live cursors and changes without save/publish/pray cycles
- Query your content lake with GROQ returning sub-100ms JSON responses shaped exactly for your React components
- Store rich content as Portable Text JSON — render identical copy on web, iOS, Alexa, signage without HTML parsing
- Cut platform spend 60–80% with Sanity's usage pricing replacing Sitecore's per-server enterprise licensing tiers
- Deploy content changes in seconds via CDN edge invalidation instead of Sitecore publish queues and cache clears
Why Enterprises Are Leaving Sitecore
Sitecore had its run. For years it was the default enterprise DXP — the safe choice for large organizations that needed personalization, multisite management, and content workflows. Safe stopped being smart a while ago.
Sitecore XP licensing costs are brutal. XM Cloud tried to modernize the stack, but underneath it's still Sitecore — opinionated, heavy, and expensive to maintain. JSS was a step toward headless, but it bolted a React layer onto a monolithic core rather than rethinking the architecture. Your developers end up debugging Sitecore-specific abstractions instead of shipping features. Your content team waits on dev cycles for changes that should take minutes.
Sanity CMS is the opposite of all that. It's a structured content platform built API-first, designed for real-time collaboration, and flexible enough to model any content domain without fighting the system.
We've led Sitecore-to-Sanity migrations for enterprises running XP, JSS, and XM Cloud. Here's what we know.
The Sitecore Pain Points That Actually Matter
Licensing and Total Cost of Ownership
Sitecore licensing can run $100K–$500K+ annually depending on your tier, modules, and user count. Add Sitecore-specialized developers (a shrinking, expensive talent pool), hosting infrastructure, and the overhead of keeping everything patched and compatible. The TCO is staggering for what you actually get.
Content Hub Lock-In
Sitecore Content Hub was supposed to solve DAM and content operations. In practice, it's another tightly coupled module that deepens your platform dependency. Replacing Content Hub with Sanity's content lake gives you a single, queryable source of truth without the vendor lock.
Developer Experience Is a Bottleneck
Sitecore development is slow. Full stop. Build times drag, local development environments are fragile, and the gap between what a component looks like in Experience Editor versus production is a constant source of bugs. JSS improved things marginally, but you're still deploying through Sitecore's pipeline.
Content Team Friction
Content editors in Sitecore work within rigid page templates. Want to reuse a content block across channels? That requires developer intervention. Want to preview changes in real time? Experience Editor's rendering lag makes that painful. Content teams end up blocked, filing tickets instead of publishing.
Personalization Theater
Sitecore's personalization engine — xDB, xConnect — sounds impressive in sales demos. In practice, most organizations use a fraction of its capabilities because the implementation cost is enormous. You're paying enterprise DXP prices for a CMS.
What Sanity Brings to the Table
Structured Content Modeling
Sanity schemas are defined in code — TypeScript or JavaScript, version-controlled in Git, reviewed in pull requests. You define document types, object types, references, and validations programmatically. Your content model becomes as rigorous and portable as your application code.
Portable Text — Sanity's rich text format — stores content as structured JSON rather than raw HTML. Your content renders correctly on web, mobile, email, kiosks, or any future channel without transformation headaches.
GROQ Content Lake
GROQ is Sanity's query language. It's expressive, fast, and purpose-built for querying structured content. Unlike GraphQL, there's no schema stitching or resolver complexity. You write a GROQ query, you get exactly the data shape you need. The content lake is a real-time, globally distributed datastore — not a database bolted onto a CMS.
Real-Time Collaboration
Multiple editors can work on the same document simultaneously. Changes appear instantly. No check-in/check-out locking, no merge conflicts, no lost work. Sanity Studio shows presence indicators so your team knows who's editing what. Think Google Docs-level collaboration, but for your CMS.
Sanity Studio: Your Custom CMS
Sanity Studio is an open-source, React-based editing environment that you own and customize. Need a custom widget for SEO scoring? Build it. Need a workflow plugin for editorial approval? Build it or install one. Studio deploys as part of your codebase — not hosted on Sanity's infrastructure — which means full control.
MACH Composable Architecture
Sanity fits cleanly into a MACH stack. It handles content. Your frontend (Next.js, Astro, Remix) handles presentation. Your commerce platform handles transactions. Your search service handles search. Each service is best-in-class, independently deployable, and replaceable. No monolith.
Our Sitecore-to-Sanity Migration Process
Phase 1: Discovery and Content Audit (2–3 weeks)
We inventory your Sitecore instance — every template, rendering, content item, media asset, personalization rule, and workflow. We crawl the site for URL structures, redirects, and SEO metadata. We map Sitecore's template hierarchy to Sanity document types and decide what to migrate, what to consolidate, and what to cut.
Deliverables: content model mapping document, migration scope, risk assessment, SEO baseline report.
Phase 2: Content Modeling in Sanity (2–3 weeks)
We design your Sanity schemas from scratch. Not a 1:1 port of Sitecore templates — a proper structured content model optimized for reuse, omnichannel delivery, and editorial efficiency. We configure Portable Text, reference structures, taxonomy systems, and localization patterns.
We set up Sanity Studio with custom input components, preview panes, and editorial workflows that match — and improve on — what your team had in Sitecore.
Phase 3: Frontend Development (4–8 weeks)
We build your frontend in Next.js (or Astro for content-heavy sites) connected to Sanity via GROQ queries. Visual Editing and live preview are configured so editors see changes in real time on the actual site — not an Experience Editor approximation.
Performance is non-negotiable. We target sub-300ms TTFB and 95+ Lighthouse scores on mobile.
Phase 4: Content Migration and Validation (2–4 weeks)
We extract content from Sitecore via API, database export, or site crawl — whatever gives us the cleanest data. Custom migration scripts transform Sitecore fields into Sanity document structures, convert rich text to Portable Text, and remap media assets to Sanity's asset pipeline.
Migration runs in phases — subset imports, validation against source, automated parity checks. Not a single high-risk cutover.
Phase 5: SEO Preservation, QA, and Launch (1–2 weeks)
Every URL gets a redirect map. We validate canonical tags, structured data, Open Graph metadata, XML sitemaps, and hreflang tags. Before-and-after crawls confirm zero SEO regression.
We train your content team on Sanity Studio, document everything, and support you through launch and the critical first weeks of production.
SEO Preservation Strategy
Sitecore migrations carry real SEO risk if handled carelessly. Our approach:
- Full URL inventory from Sitecore sitemap and crawl data, cross-referenced with Google Search Console
- 301 redirect mapping for every indexed URL, implemented at the edge (Vercel, Netlify, or Cloudflare)
- Metadata migration — title tags, meta descriptions, OG tags, structured data all ported and validated
- Internal link audit — every internal link updated to prevent redirect chains
- Post-launch monitoring — Search Console indexing, Core Web Vitals, and rank tracking for 90 days
We've migrated sites with 50K+ pages without losing organic traffic. The key is treating SEO as a first-class workstream, not an afterthought.
Timeline and Pricing
Most Sitecore-to-Sanity migrations run 12–20 weeks depending on content volume, number of sites, localization complexity, and frontend scope.
| Scope | Timeline | Investment |
|---|---|---|
| Single site, <5K pages | 12–14 weeks | $80K–$150K |
| Multi-site, 5K–50K pages | 14–18 weeks | $150K–$300K |
| Enterprise, 50K+ pages, multi-brand | 18–24 weeks | $300K+ |
These numbers are a fraction of what most organizations spend annually on Sitecore licensing alone. The migration pays for itself within the first year through reduced licensing, hosting, and development costs.
The MACH Composable Stack We Deploy
Post-migration, your architecture looks like this:
- Content: Sanity CMS (Content Lake + Studio)
- Frontend: Next.js or Astro on Vercel/Netlify
- Search: Algolia or Typesense
- Commerce: Shopify, commercetools, or Medusa (if applicable)
- Media: Sanity Asset Pipeline or Cloudinary
- Analytics: Plausible, Fathom, or GA4

Common questions
Wie lange dauert eine Sitecore-zu-Sanity-Migration?
Die meisten Migrationen liegen zwischen 12 und 20 Wochen. Die großen Variablen sind das Content-Volumen, wie viele Sites Sie betreiben, und die Komplexität der Lokalisierung. Eine einzelne Site mit unter 5.000 Seiten wird normalerweise in 12–14 Wochen abgeschlossen. Multi-Site-Enterprise-Arbeiten — 50K+ Seiten, mehrere Brands — können sich auf 18–24 Wochen erstrecken. Wir führen durchgehend phasierte Migrationen durch, sodass Sie nicht alles auf einen Cutover setzen.
Werden wir während der Migration organischen Such-Traffic verlieren?
Nein, wenn es richtig gemacht wird. Wir erstellen 301-Redirect-Maps für jede indexierte URL, migrieren alle Metadaten und strukturierten Daten, prüfen interne Links und beobachten die Search Console 90 Tage lang nach dem Launch. Wir haben Sites mit 50K+ Seiten verschoben und den organischen Traffic während der gesamten Migration intakt gehalten.
Kann Sanity Sitecore Content Hub ersetzen?
Ja. Sanitys Content Lake funktioniert als zentrales, echtzeit-Inhalts-Repository — strukturierte Dokumenttypen, Asset-Management, GROQ-Abfragen. Es deckt ab, was Content Hub im täglichen Betrieb tatsächlich leistet: Content-Speicherung, Taxonomie, Workflow. Ohne den Lizenzierungsaufwand. Für schwerere DAM-Anforderungen integrieren wir Cloudinary oder ähnliches.
Wie handhabt Sanity die Personalisierung, die Sitecore XP bot?
Sanity verwaltet Content-Speicherung und -Delivery. Personalisierung wird auf die Edge- oder Frontend-Ebene verschoben — Vercel Edge Middleware, LaunchDarkly oder benutzerdefinierte Next.js-Logik, je nachdem was Sie brauchen. Dieser komponierbare Ansatz schneidet in der Praxis besser ab als Sitecore xDB, weil jedes Tool eines sehr gut macht und Sie sie unabhängig voneinander anpassen können.
Was passiert mit unseren Sitecore JSS-Komponenten?
JSS React-Komponenten werden als Standard-Next.js-Komponenten neu erstellt, die über GROQ-Abfragen von Sanity abrufen. Die Business Logic und das Design bleiben erhalten, aber die Sitecore-spezifischen Abstraktionen — Layout Service, Placeholders, alles — werden entfernt. Übrig bleibt sauberer, schnellerer Code, den jeder React-Entwickler in Ihrem Team tatsächlich verwalten kann.
Wie viel kostet eine Sitecore-zu-Sanity-Migration im Vergleich zur Sitecore-Verlängerung?
Die Migration kostet typischerweise $80K–$300K+ je nach Umfang, was oft weniger ist als ein einzelnes Jahr Sitecore-Lizenzierung und Wartung. Sobald Sie Sitecore verlassen, fallen die jährlichen Plattformkosten stark ab. Sanitys nutzungsbasierte Preisgestaltung zusammen mit Vercel- oder Netlify-Hosting ist ein Bruchteil dessen, was Sitecore TCO kostet. Die meisten Clients erreichen vollständige ROI innerhalb von 12 Monaten.
