+### Railway (backend)
+
+1. En el dashboard del servicio, cambia el repo conectado a `JBDev23/hydraflow`.
+2. **Root Directory:** `hydraflow-backend`
+3. **Build Command:** `pnpm install --frozen-lockfile && pnpm build`
+4. **Start Command:** `pnpm start`
+5. Variables de entorno sin cambios: `DATABASE_URL`, `DIRECT_URL`, `JWT_SECRET`, etc.
+
+pnpm detectará el workspace padre (`pnpm-workspace.yaml` en la raíz del repo clonado).
+
+### Expo EAS (app)
+
+1. Reconecta el proyecto EAS al repo `JBDev23/hydraflow`.
+2. **Root directory:** `hydraflow-app` (o ejecuta `eas build` desde esa carpeta).
+3. Asegúrate de que el build incluye `pnpm-workspace.yaml` y `pnpm-lock.yaml` de la raíz.
+4. Tras la migración, lanza un build de preview para verificar.
+
+### GitHub Actions
+
+El workflow [`.github/workflows/ci.yml`](.github/workflows/ci.yml) se activa automáticamente en el nuevo repo. Recrea los secrets y branch protection rules si los tenías en los repos antiguos.
