Migrate when you need to monitor multiple source repositories or want to consolidate deployments. + +### Q: Can I mix legacy and new formats? + +**A:** No. Each configuration file must use either the legacy format OR the new format, not both. However, you can have different deployments using different formats. + +### Q: What happens if I don't specify installation_id? + +**A:** The application will use the default `INSTALLATION_ID` from environment variables. This works fine if all your source repositories are in the same organization. + +### Q: Can I gradually migrate one source at a time? + +**A:** Yes. You can start with one source in the new format and add more sources over time. Keep your old deployments running until all sources are migrated. + +### Q: How do I test without affecting production? + +**A:** Use dry-run mode (`DRY_RUN=true`) to test configuration without making actual commits. Also test in a staging environment first. + +### Q: What if a webhook comes from an unknown source? + +**A:** The application will log a warning and return a 204 No Content response. No processing will occur. Check your configuration to ensure all expected sources are listed. + +### Q: Can different sources target the same repository? + +**A:** Yes! Multiple sources can target the same repository with different copy rules. The application handles this correctly. + +### Q: How are metrics tracked for multiple sources? + +**A:** Metrics are tracked both globally and per-source. Use the `/metrics` endpoint to see breakdown by source repository. + +## Support + +If you encounter issues during migration: + +1. Check the [Troubleshooting Guide](TROUBLESHOOTING.md) +2. Review application logs for errors +3. Use the config-validator tool to identify issues +4. Consult the [Multi-Source Implementation Plan](MULTI-SOURCE-IMPLEMENTATION-PLAN.md) + +## Next Steps + +After successful migration: + +1. Monitor metrics and audit logs +2. Optimize copy rules for performance +3. Consider enabling additional features (Slack notifications, etc.) +4. Document your specific configuration for your team +5.
