  "how": {
    "incantation": "When a repository contains `railway.json` or `railway.toml`, run `railway config migrate` to preview its translation to IaC. Run `railway config migrate --apply` to write the generated file and clear the linked service’s Railway Config File setting.",

      "railway config migrate",
      "railway config migrate --apply",
      "railway config migrate --lang py --apply"

    "gotchas": [
      "Version: v5.42.0",
      "--apply: Writes the generated file and clears Railway Config File settings; without it, the command previews the file.",
      "--lang <py|go>: Selects Python or Go output; TypeScript is the default. Python and Go authoring are beta.",
      "--service <name>: Migrates only the named service; a single-service migration writes a named `partial` export.",
      "--delete-files: Optionally deletes the old Config as Code files when used with `--apply`.",
      "Migration defaults to dry-run.",
      "The CaC to graph/DSL translation runs in the CLI; thin language SDKs remain authoring-only."
    ]
  },
  "why_it_matters": "When a repository uses `railway.json` or `railway.toml`, migrate its configuration to IaC.",
  "before": "For manual migration, the docs say to import the current project with `railway config pull --force`, translate the desired settings into the IaC DSL, remove the old config file, and clear a custom config-file path in service settings if set.",
