How much does a documentation migration cost?

Basic migrations start at $4,900 for up to 500 pages. Docusaurus projects typically start at $6,400 because they include repository, build, deployment, and framework setup. Standard migrations with more structure or one publish-ready OpenAPI specification start at $10,500. We review the scope before issuing the final proposal.

Should we migrate to Docusaurus or GitBook?

Choose Docusaurus when ownership, customization, self-hosting, and deep React integrations matter most. Choose GitBook when your team wants a managed platform, visual editing, built-in search, and less infrastructure to operate. We can assess your content, contributors, and integration needs before recommending either destination.

Can an importer or AI migrate the documentation for us?

Importers and AI can accelerate the first conversion pass. The production work is preserving navigation, metadata, links, assets, reusable content, redirects, API references, search, and the release workflow. We combine automation with validation of the agreed destination and publishing workflow.

What happens to our existing documentation URLs?

We inventory the agreed source URLs and map their destinations. Redirect implementation depends on access to the original domains and hosting configuration. We identify those dependencies and coordinate cutover with your technical team before launch.

Can you migrate our API documentation too?

Yes. We can publish valid OpenAPI definitions, upgrade or repair Swagger and OpenAPI files, and reconstruct definitions from Postman collections, source code, or manually maintained endpoint pages. We also migrate GraphQL and AsyncAPI references.

Documentation migration - Move your documentation with a plan for launch.

We migrate legacy and outgrown documentation into a platform your team can operate. The scope covers conversion, structure, links, publishing, and the checks needed before the move goes live. We also plan search and agent access where the destination and project require them.

Discuss your migration

A migration that is ready to launch

Conversion is only one part of the move. We deliver the routing, validation, workflow, and launch work around it.

Content and structure

We map navigation, hierarchy, metadata, reusable content, and platform-specific components before conversion.

URLs that keep working

We inventory the agreed source URLs, map destinations, and validate redirects. Old-domain and hosting access are launch dependencies.

Validated content and navigation

We check navigation, links, rendering, and search against the agreed acceptance criteria. AI retrieval evaluation is included when specified in the scope.

A maintainable workflow

Git Sync or CI/CD, repository conventions, branch governance, and technical handoff are part of delivery.

Choose your destination

Docusaurus is our primary destination for ownership and customization. GitBook is the managed option for teams that want less infrastructure to operate.

Open-source framework

Docusaurus

An open-source React and MDX stack for teams that want full ownership, deep customization, versioning, and control over hosting and integrations.

Sources we can migrate

We migrate content from documentation platforms, legacy authoring systems, static sites, and document collections.

Documentation platforms

Confluence, GitBook, ReadMe, Mintlify, and Notion

Legacy authoring systems

DITA/XML, MadCap Flare, RoboHelp, and FrameMaker

Static documentation

Sphinx, MkDocs, custom static sites, and legacy wikis

API reference migration

Move the API reference with the documentation

We migrate REST, GraphQL, and event-driven API references into Docusaurus or GitBook. We preserve the relationship between guides and endpoints, then validate the published experience before launch.

Reference sources

OpenAPI and Swagger

GraphQL schemas

AsyncAPI specifications

Handwritten endpoint pages

Migration work

Publish valid definitions

Repair or upgrade specifications

Reconstruct OpenAPI when needed

Validate rendering and links

Choose a starting point for your migration

Page count establishes the baseline. Format, extraction, destination setup, versions, languages, repositories, and API references determine the final proposal.

How the migration runs

A representative pilot establishes the conversion and integration work before the full rollout.

1. Inventory and pilot

Select a representative slice, test extraction and conversion, and identify decisions that affect effort and risk.

2. Convert and validate

Implement the pipeline and destination, review exceptions, and check content, navigation, redirects, media, and reference rendering against the agreed scope.

3. Launch and hand over

Coordinate the agreed cutover, verify the published result, and train the team on contributions and operation.
