Contentful to Sanity Migration in York
Moving York organisations from Contentful to Sanity, where the body content is what needs work. The two platforms represent rich text as different structures — with embedded entries, links and marks arranged their own way — so article bodies have to be transformed rather than transferred, and that transformation is the migration.
Why this comes up
The problem
Rich text exported from Contentful arrives as a structure Sanity cannot interpret.
What you get
What we deliver
- Rich text converted between the two document structures, not copied across
- Embedded entries and assets within body content preserved through the conversion
- References between documents remapped, since identifiers change
- Content model translated to Sanity's schema definitions in code
- Assets migrated with their metadata rather than only their files
- Conversion verified on real content, because the difficult cases are in the archive

Working in York
Yorkshire & the Humber
York's economy leans heavily on heritage tourism, and the practical constraint here is often that a visitor-facing system has to handle enormous seasonal swings on a small operator's budget.

Contentful to Sanity Migration in York — common questions
- Why can rich text not simply be moved?
- Because the platforms model it differently. Both represent formatted content as structured data rather than markup, but the shapes disagree — so a converter has to be written and, more importantly, checked against the varied content that has accumulated over years.
- What happens to embedded entries?
- They need handling explicitly. Content with an embedded product card, callout or related article inside the body is the part conversions break on, and a migration tested only against plain paragraphs will appear to work until an editor opens something real.
- Do references survive?
- Only if remapped. Documents referencing each other by identifier need those identifiers translating as part of the migration, and a run that imports documents before their targets exist produces references pointing at nothing.
- How should the conversion be verified?
- Against the oldest and strangest content you have. Recent articles follow current conventions and convert cleanly, whereas the archive contains formatting decisions nobody remembers making — and those are exactly the pages that will be noticed if they arrive broken.
- Do you work with businesses across North Yorkshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Yorkshire & the Humber, including York and the surrounding North Yorkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of York businesses do you usually work with?
- Visitor-facing booking and ticketing systems that handle extreme seasonality on a small operator's budget. Beyond that we work across Tourism & Heritage, Rail Engineering, Bioscience, Retail and Higher Education.
- Do you cover the areas around York?
- Yes — we work throughout Yorkshire & the Humber, including Leeds, Newcastle, Sheffield. York is an urban area of roughly 210,000+, and we take on work across the wider North Yorkshire region rather than the city boundary alone.
