Here's how to migrate your Prefect database to a new version: 1. Using the CLI (Recommended Method):

bash
prefect server database reset-db

This command will automatically handle the migration to the latest version. 2. Environment Configuration: Before migrating, especially for large databases, set an adequate timeout:

bash
export PREFECT_API_DATABASE_TIMEOUT=300  # 5 minutes, adjust as needed

3. For Docker Deployments: If you're running Prefect in Docker, include the timeout in your docker run command:

bash
docker run -e PREFECT_API_DATABASE_TIMEOUT=300 prefecthq/prefect:latest

Important Safety Tips: - Always backup your database before performing migrations - Ensure no active workflows are running during the migration - For production environments, consider testing the migration in a staging environment first If you encounter any issues during migration or need to perform more complex operations (like rolling back to a previous version), let me know and I can provide more specific guidance. For more details, you can refer to the server database documentation.
