Chapter 5. Troubleshooting migration issues
If you encounter issues during migration, use the following guidance.
Export fails:
- Check the authentication credentials are valid
- Verify 2.6 is accessible
- Review registry logs for errors
Import fails:
- Verify export file is valid ZIP format
- Check Apicurio Registry 3.x has sufficient storage
- Review registry v3 logs for specific errors
- If partial import occurred, drop v3 database (or Kafka topic) and retry
Baseline metrics mismatch:
- Review import logs for skipped artifacts
- Check for import errors or warnings
- Verify export file integrity
- Consider re-exporting and re-importing
Rollback needed:
- Switch load balancer back to 2.6
- Investigate v3 issues
- Recovery time: 30-60 seconds
- v2 data unchanged (export was read-only)
