Documentation Platform Migration Checklist

A practical checklist for moving documentation platforms without losing pages, search traffic, AI access, analytics, or reader trust.

Use this checklist when moving from one documentation platform, framework, or hosting provider to another. The safest migration creates a complete private replacement, validates it, and only then changes public routing.

For the reasoning behind each step, read how to migrate documentation without losing SEO or GEO.

Phase 1: Establish the Baseline

• Export every indexable URL from the sitemap and a crawler.
• Export Search Console clicks, impressions, queries, and index status by page.
• Export analytics sessions, conversions, and landing pages.
• Identify pages with backlinks.
• Record current canonicals, titles, descriptions, and structured data.
• Save the current robots.txt and XML sitemaps.
• Record Markdown, llms.txt, MCP, OpenAPI, and other agent entry points.
• Capture current Core Web Vitals and representative Lighthouse tests.
• Identify forms, feedback tools, analytics, and support widgets.

Phase 2: Decide What Changes

• Keep the existing custom domain if possible.
• Keep high-value paths unchanged wherever possible.
• Assign each old URL one action: keep, rewrite, merge, redirect, or remove.
• Map every changed URL to one relevant final destination.
• Mark pages that should return 404 or 410 because no replacement exists.
• Confirm locale, version, asset, and trailing-slash behavior.
• Separate platform migration work from optional content redesign.

Phase 3: Build the Private Replacement

• Import or recreate all pages, images, code examples, and downloadable files.
• Rebuild navigation and page hierarchy.
• Preserve page intent, prerequisites, examples, warnings, and troubleshooting.
• Add one accurate canonical per indexable page.
• Recreate metadata and valid structured data.
• Validate internal links and anchors.
• Confirm mobile and accessible behavior.
• Configure search and analytics.
• Generate a clean sitemap from final canonical URLs.
• Validate machine-readable documentation outputs.

Phase 4: Test the Migration

• Crawl the private site and fix broken internal links.
• Test every redirect in the URL map.
• Ensure changed URLs redirect once to a 200 page.
• Remove redirect chains and loops.
• Test query parameters, versions, locales, uppercase paths, and trailing slashes.
• Confirm public pages are not blocked by authentication or robots.txt.
• Inspect rendered HTML rather than only the browser view.
• Compare representative old and new pages for content parity.
• Test forms, code copy, search, feedback, and API playgrounds.
• Test important pages from multiple devices and regions.

Phase 5: Prepare the Cutover

• Lower DNS TTL when required by the hosting change.
• Freeze old-site URL changes during the final migration window.
• Export a final content and URL snapshot.
• Prepare rollback instructions and name one decision owner.
• Verify the new production origin directly.
• Confirm SSL, custom domain, redirects, sitemap, and analytics.
• Schedule the launch when engineering and content owners are available.

Phase 6: Launch

• Change DNS or routing.
• Verify the homepage and several deep documentation pages.
• Verify old URLs redirect to the correct destinations.
• Confirm canonical tags use the public domain.
• Submit the final sitemap in Search Console.
• Inspect representative URLs in Search Console.
• Confirm analytics events and conversions are arriving.
• Monitor 404, 5xx, redirect, and crawler logs.

Phase 7: Monitor the First Month

• Compare clicks, impressions, indexed pages, sessions, and conversions to baseline.
• Review pages with the largest traffic decline.
• Fix unexpected 404 and soft-404 behavior.
• Check crawl stats and sitemap processing.
• Verify AI readers can still retrieve core tasks and examples.
• Review Core Web Vitals using field data when available.
• Keep permanent redirects in place for at least one year, ideally longer.
• Do not remove the old platform until rollback and content-export requirements are satisfied.

Migration Acceptance Criteria

Do not call the project complete until:

• every valuable old URL resolves or redirects correctly
• no canonical points at staging or the old platform
• the sitemap contains only final canonical URLs
• analytics and conversions work
• search and agent entry points return current content
• ownership for ongoing monitoring is explicit

If you are still deciding whether the move is worth it, use the documentation hosting cost calculator before the migration begins.
