title: Migrate an Existing App
description: Quickly migrate your existing app to a mini app, preview it in Base Build, and publish to the Base app.
---
+
+
+**Deprecated:** This guide is for the legacy Mini App flow using Farcaster manifests. As of April 9, 2026, the Base App treats all apps as standard web apps.
+
+**For most developers:** Use the [Migrate to a Standard Web App](/mini-apps/quickstart/migrate-to-standard-web-app) guide instead. You only need this legacy flow if you specifically require Farcaster integration (frames, cast actions, etc.).
