Migration guide

Can you migrate Sitecore to Sanity?

Last updated: · By the Replatform Radar team — specialists in pre-migration CMS content audits

Yes — you can migrate from Sitecore to Sanity, but it is a substantial architectural shift rather than a content export. Sitecore is a coupled .NET digital experience platform with an item tree, templates, renderings, and built-in personalization, while Sanity is a developer-first headless CMS where the schema is defined as code and the front end is rebuilt separately, usually in a framework like Next.js. Your content moves into Sanity's document model with rich text stored as Portable Text, and everything that Sitecore rendered server-side becomes the responsibility of a new front end. The payoff is a faster, more flexible, API-driven stack; the cost is rebuilding presentation and replacing platform features Sitecore gave you out of the box.

Sitecore organizes content as items in a tree, defined by templates and presented through renderings and layouts, with personalization, marketing automation, and delivery bundled into one .NET platform. That integration is powerful but heavy: upgrades are involved, the front end is tied to Sitecore's rendering, and licensing and infrastructure are significant commitments. Teams moving to Sanity are usually trading that all-in-one model for a decoupled, composable architecture.

Sanity is a headless, API-first CMS whose defining trait is schema-as-code: content types are defined in JavaScript/TypeScript, queried with GROQ, and edited in the customizable Sanity Studio. Rich text is stored as Portable Text, a structured JSON format, rather than raw HTML, and content is delivered over APIs to a separately built front end. The migration therefore has two tracks: modeling and moving content into Sanity, and building a new presentation layer that consumes it.

FAQ

Sitecore to Sanity: frequently asked questions

Can you migrate Sitecore to Sanity?

Yes. Content from Sitecore templates and items maps to Sanity document types and documents, and rich text converts to Portable Text. The larger job is rebuilding the front end, since Sanity is headless and does not render pages the way Sitecore does.

How is Sitecore rich text converted to Sanity?

Sitecore stores rich text as HTML, while Sanity uses Portable Text, a structured JSON format. Conversion requires parsing the HTML and mapping elements, embedded media, and inline components to Portable Text blocks; it is a transformation step, not a direct copy.

Does Sanity replace Sitecore personalization and analytics?

No. Sanity is a content platform and does not include Sitecore's personalization, xDB analytics, or marketing automation. Teams that need those add dedicated personalization, analytics, and campaign tools alongside Sanity.

What front end do you use with Sanity after Sitecore?

Most teams build a custom front end, commonly with Next.js, that queries Sanity over GROQ. Sitecore renderings and layouts do not transfer, so the presentation layer is rebuilt as framework components.
