Readme to Glean Migration

MIGRATION OVERVIEW

Why teams migrate from Readme to Glean

The core problem

Migrating from ReadMe to Glean is not a traditional content migration but a content-to-search-index translation, as no native Glean connector for ReadMe exists. ReadMe organizes content in a hierarchical, project-centric documentation hub using MDX with custom components, versioned branches, and dynamically rendered OpenAPI references, while Glean operates as a flat enterprise knowledge graph that indexes plain text documents with titles, URLs, permissions, and metadata. Teams must extract content via the ReadMe API or a web crawler, transform MDX into plain text or HTML, flatten hierarchical structures and OpenAPI specs into indexable documents, and push the results through Glean's Indexing API as a custom datasource. Custom engineering work of 3–5 days is typically required for the API-based path, which is necessary for private, versioned, or API-heavy documentation projects.

Why this matters for your migration

KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Readme to Glean migration.

Most Critical

MDX to Plain Text Conversion

ReadMe stores content as MDX with custom components such as callouts, tabs, accordions, and reusable content blocks that have no equivalent in Glean's document schema and must be stripped or converted to plain text or HTML before indexing.

Blocks all downstream imports if mapped wrong

Hierarchical Structure Flattening

ReadMe's nested version/branch/category/page/subpage hierarchy must be flattened into individual Glean documents while preserving contextual metadata such as category name, parent page, and version label.

OpenAPI Reference Transformation

ReadMe's interactive API reference pages point to OpenAPI specs that are dynamically rendered on the frontend, meaning the raw specs must be parsed and flattened into structured text before Glean's AI can accurately answer queries about endpoint parameters or schemas.

Versioned Content Strategy

ReadMe supports multiple documentation versions via branches, requiring teams to explicitly decide which versions to index in Glean, since indexing deprecated versions risks degrading search accuracy with outdated context.

No Native Connector or Incremental Crawl

There is no native Glean connector for ReadMe, and the Website connector alternative has a default 28-day refresh cycle with no incremental crawl mode, making it unsuitable for private deployments or teams requiring frequent content freshness.

Permission and Access Control Mapping

ReadMe enforces only project-wide access controls with no per-section permissions, so teams requiring granular document-level ACLs in Glean must implement custom permission logic in their Indexing API pipeline.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

Migration between platforms is full of edge cases. Our engineers have identified every risk from Readme to Glean and built proven solutions for each one.

High complexity

API Reference Pages

API reference pages do not contain a standard text body and instead point to OpenAPI specification files that must be separately downloaded, parsed, and flattened into structured text for Glean to index endpoint-level details accurately.

Solved
Embedded Images

Images in ReadMe pages are hosted on ReadMe's CDN and are not included in exports, meaning if the ReadMe account is closed or CDN links change, all image references in the indexed documents will break permanently.

Solved
v2 API Projects (ReadMe Refactored)

Projects using ReadMe Refactored do not support the legacy v1 API routes for categories and docs, requiring a fully separate extraction pipeline using v2 branch-based endpoints that must be identified and confirmed before any development begins.

Solved
OpenAPI Specification Files

Raw OpenAPI JSON or YAML files must be fetched separately via the API specification endpoint and transformed into human-readable structured text, as Glean cannot natively render or interpret OpenAPI schemas during indexing.

Solved

Custom engineering

Guide Pages

Guide pages with standard Markdown body content migrate reliably, but custom MDX components such as callouts, tabs, and reusable content blocks require explicit stripping or conversion logic to produce clean indexable text.

Handled
Changelog Entries

Changelogs use their own API family and are documented as versionless in ReadMe, meaning teams that only extract guides will silently omit all changelog content unless they add a separate extraction step.

Handled
Custom Pages

Custom pages use a distinct API endpoint family separate from guides and must be extracted independently, and any MDX or embedded components on these pages carry the same conversion risk as guide pages.

Handled
Reusable Content Blocks

Shared reusable snippets are typically inlined when a page is exported, but this behavior should be explicitly verified during the inventory phase to ensure no content is silently omitted from the index.

Handled
Versioned Documentation Branches

Multiple documentation versions mapped to ReadMe branches must be deliberately scoped during extraction, as indexing all versions indiscriminately risks polluting Glean search results with deprecated or legacy content.

Handled
Document Permissions and ACLs

ReadMe enforces only project-level access controls with no per-section granularity, so any document-level ACL requirements in Glean must be designed and implemented entirely within the custom Indexing API pipeline.

What does an Engineer-led migration mean anyway?

Speed & Accuracy: Our Blended Method

We blend automation (smart scripts, bulk APIs) with human expertise for speed without risk. Our engineers manually check every mapping, validation, and exception.

You get:

Speed of automation for bulk record migration
Precision of engineers verifying integrity and business logic
Pilot migrations and sandbox testing to catch issues early
Real-time validation reports and rollback readiness

Result: 50x faster migrations than manual imports — with near-zero error rates.

Handling the Tricky Tech and API Details

The Readme and Glean APIs each behave differently, which is where our engineers shine. We build custom logic to handle the data quirks where generic tools typically break.

We handcraft API logic for:

Field mapping and transformation
Pagination, rate-limit handling, and throttling
Preserving article history, media, and author metadata
Syncing custom fields, categories, and tags without breaking structure

Our scripts: Natively retry failed calls, re-queue large attachments, and ensure data parity.

No Guesswork

We don't just promise smooth migrations—we measure and prove them. Every client receives a Migration Validation Report with all metrics.

Typical results across projects:

100% record-count parity between your Readme data and Glean
Zero downtime during staged cutovers
99.9% attachment integrity (verified via checksum)
Full automation and preservation of all business rules

Our standard: Includes full SEO and category-structure preservation and 30 days of engineer-assigned support post go-live.

We Adapt to Your Setup (Not the Other Way Around)

No two teams configure Readme or Glean exactly the same way—with unique content structures and data. We customize every migration script to fit your exact workflow, categories, and tags.

Our engineers adapt for:

Custom fields, categories, and workflows
Multi-brand or multi-language setups
Historical imports and partial (date-based) migrations
Integration re-mapping for search, chat, or feedback tools

The promise: If your data doesn't fit a standard template, we build one just for you.

FAQ

Frequently Asked Questions

Everything you need to know about migrating from Readme to Glean. Can't find what you're looking for? Talk to our team.

Does Glean have a native ReadMe connector?

No. Glean does not include a native connector for ReadMe. You need to build a custom connector using Glean's Indexing API (Push API) to extract content from ReadMe and push it into Glean as a custom datasource.

Can Glean natively render ReadMe OpenAPI specifications?

No. Glean is an enterprise search and RAG platform, not an API documentation renderer. You must flatten your OpenAPI JSON/YAML into plain text or structured Markdown before indexing it in Glean.

How do I export all pages from ReadMe programmatically?

Use ReadMe's API: call GET /categories to list all categories, then GET /categories/{slug}/docs for each category, then GET /docs/{slug} for each page. For ReadMe Refactored projects, use the v2 API with branch-based endpoints instead.

What happens to images hosted on ReadMe after migration?

Images hosted on files.readme.io will break if your ReadMe account is closed. You must programmatically download these assets, re-host them on an internal CDN or cloud bucket, and rewrite the markdown links before pushing to Glean.

Can I keep ReadMe and Glean in sync automatically?

Yes. Use a scheduled job that re-runs your extraction pipeline and pushes via Glean's bulk indexing endpoint, or trigger incremental updates via GitHub Actions when docs are pushed to your GitHub-synced ReadMe repo. ReadMe page endpoints support ETags for efficient change detection.

How long does the Readme to Glean migration take?

Most migrations complete within 1–5 business days, depending on data volume and complexity. We provide a detailed timeline after the initial assessment and can often complete small migrations in under 24 hours.

Will my team lose access to Readme during the migration?

No. Your source system remains fully operational throughout the entire migration. We run the migration in the background with zero downtime to your current operations.

Will there be downtime when migrating from Readme to Glean?

No. Our migration process is designed for zero downtime. We use a staged approach with background sync and a fast cutover, ensuring no disruption to your live business operations.

How do I validate that everything migrated correctly?

Every client receives a Migration Validation Report with comprehensive metrics including record-count parity, attachment integrity verification via checksum, and full audit logs. We also offer unlimited sample migrations so you can verify before committing.

Do I need professional help for this migration?

While simple migrations can sometimes be handled in-house, professional help ensures zero data loss, proper field mapping, and preservation of relationships between records. Our engineer-led approach catches edge cases that automated tools miss.

Does ClonePartner provide guidance before committing?
