This guide outlines the process of migrating an application from Cloudflare Pages to Railway platform. The migration process varies depending on the project's architecture and configuration. The key differences between Cloudflare Pages and Railway include database support, server-side languages and frameworks, Dockerfile support, and headers. The general migration procedure involves creating a new Railway project, configuring environment variables, deploying the service, testing the deployment, deleting the Cloudflare project, and updating the package.json file. Specific steps are provided for cases involving framework presets, redirects, and custom headers. The guide emphasizes the importance of reviewing each case individually and following the general migration procedure as a foundation.
