Migration from Render to CreateOS

Use this guide when your app runs on Render as a web service, static site, worker, or cron job.

What changes

Step by step

1. Open the Render service and collect:
   • Service type
   • Repository and branch
   • Build command
   • Start command
   • Runtime
   • Port
   • Environment variables or environment group
   • Health check path
   • Custom domains
2. Check whether the project has a render.yaml file. If it does, use it as the migration checklist.
3. Sign into createos.sh/app.
4. Click Deploy.
5. Import the same GitHub repository.
6. Choose Manual and enter the known build/start settings, or use Build with AI for framework detection.
7. Add environment variables.
8. Configure the port and deploy.
9. Verify the app from the CreateOS deployment URL.

Render-specific checks

• Convert Render background workers into separate CreateOS services.
• Convert Render cron jobs into CreateOS cron jobs.
• If the service uses a persistent disk, move that data to a supported persistent storage option before switching traffic.
• If the service uses Render-managed Postgres or Redis, migrate the database or keep using the external connection string.
• Update webhook URLs and callback URLs after the CreateOS domain is live.

Cutover

1. Deploy and verify the CreateOS service.
2. Run smoke tests against production-like data.
3. Add the custom domain in CreateOS.
4. Update DNS.
5. Keep the Render service available until traffic has fully moved.
