Getting a 404 when trying to reach page: https://guides.wheels.dev/v3-0-0/upgrading/3-0-0-config-migration/ from page: https://guides.wheels.dev/v4-0-0-snapshot/upgrading/2x-to-3x/

Thanks for the heads-up! Fixed in https://github.com/wheels-dev/wheels/pull/2429 — the v3 docs page filename had dots in it (3.0.0-config-migration.md), and Astro's slug generator strips dots entirely rather than converting them to dashes, so the live URL was actually /v3-0-0/upgrading/300-config-migration/ instead of what the link expected. Renamed the file to use dashes, added a redirect from the old URL, and added it to the v3 sidebar (it was orphaned from there too). Should be live once the PR merges and the guides site redeploys.
