Sanity Migration · Portsmouth
Sanity Migration in Portsmouth
Migrating content into Sanity for Portsmouth organisations, where rich text is structured rather than stored as markup. Formatted content becomes an array of blocks with defined types, so an import from an HTML-based system has to convert that markup into structure — and anything embedded within it needs a block type to become.
Why this comes up
The problem
Articles contain embedded videos, callouts and image galleries inside the HTML, and the import is treating it all as plain text.
What you get
What we deliver
- Rich text converted to structured blocks rather than stored as a markup string
- Embedded elements identified and given block types they can convert into
- References resolved so related content links properly rather than by name
- Assets uploaded and re-linked, with originals retained where quality matters
- Import scripted and repeatable, so a partial run can be resumed
- Content verified in the studio, since a technically valid import can still look wrong

Sanity Migration in Portsmouth — common questions
- Why not store the HTML as-is?
- Because it discards the reason for migrating. Structured rich text can be rendered differently per front end, have custom blocks styled to your design system and be queried — storing markup gives you a content management system that can only reproduce what was pasted into it.
- What happens to embedded content?
- It needs a block type. A video embed, a pull quote or a gallery inside an article becomes a defined block that templates render deliberately — which is better than an embed code stored as text, and it means identifying those patterns before importing.
- Should the import be scripted?
- Always, and made resumable. Content imports fail partway on unexpected data, and a script that records progress lets you fix the case and continue rather than starting again or leaving a half-populated dataset to reconcile.
- Is a successful import enough?
- No — someone should look at the content. An import can complete without errors while producing articles with lost formatting, broken references or images in the wrong place, and only opening a sample in the studio reveals that.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
