API documentation migration works when authored guides and generated reference pages keep separate source records, while routes, components, examples, and build inputs are tested together on the target.
Identify which system owns every rendered field
An API reference may combine an OpenAPI document, generated descriptions, hand-authored introductions, reusable examples, code-sample configuration, and custom components. A migration that copies the rendered page can sever those sources, while a generator-only migration can erase the human context that made the reference usable.
The source map labels every page and field as generated, authored, merged, or external. It records the generator command, schema location, overlays, manual-content boundary, and owner. The target build should preserve that ownership so regeneration updates machine-derived fields without overwriting reviewed prose.
Port components and routes before bulk generation
Representative endpoints should exercise authentication blocks, parameters, nested schemas, enums, examples, errors, code tabs, deep links, and large response models. Those pages expose target limitations early. ReadMe's migration service includes content audit, automated transfer, manual review, and validation because conversion alone cannot prove that source features survived.
Generated routes also need a deterministic map. Operation IDs, tags, versions, and path naming can produce different URLs on a new platform. The migration records every old generated route, its target, redirect, canonical, and navigation parent before the full reference is published.
Verify the generator in the deployment environment
The acceptance run starts from the source contract, generates the complete reference in a clean environment, builds the production site, and checks route count, errors, broken links, missing examples, schema rendering, and preserved manual content. A second run should produce the same output without erasing edits. The editor runbook then explains how a contract change reaches preview and production.
Where the service stops
Reality Contact, LLC migrates and validates the agreed documentation corpus, but does not decide product policy, invent missing API behavior, approve legal or security content, publish private documentation publicly, or switch the production domain without buyer authorization. The buyer approves keep, merge, retire, route, component, and access decisions, supplies content owners, and switches or authorizes the production domain after build, redirect, accessibility, and parity checks pass. The work is documentation implementation and document preparation, and it does not replace legal, security, accessibility, compliance, or product advice. The buyer owns every content, access, route, retirement, component, claim, and production-domain decision.
