Before upgrading Apache Superset, backup the current metadata database and export dashboards to avoid data loss. Follow these steps for a smooth upgrade:
1. Check release notes: Review changes in the new version, identify potential issues, and plan accordingly.
2. Update dependencies: Ensure compatibility with other software components by updating Python packages and system libraries.
3. Install the new version: Use pip or another package manager to install the updated Superset package.
4. Run database migrations: Execute ‘superset db upgrade’ command to apply schema changes to the metadata database.
5. Validate customizations: Test any custom visualizations, plugins, or configurations for compatibility with the new version.
6. Perform thorough testing: Verify functionality of core features, user workflows, and performance metrics.
7. Monitor post-upgrade: Observe logs, error reports, and user feedback to address any unforeseen issues.
