9022 Legacy data upgrade failed
Meaning
The current software and data versions are not compatible: legacy data upgrade failed.
Common Causes
- The project or data was created by a newer, older, or unsupported format version.
- An automatic upgrade or conversion could not complete.
Resolution Steps
- Back up the complete original project or data before conversion.
- Use the supported software version and official upgrade/export path; use an intermediate version if documentation requires it.
- Do not edit version fields or extensions. Preserve the unchanged original and upgrade log for support.
