  Review Logs: Check the logs for the migration process to identify any previous errors or warnings that might have led to this state.
  
  
  Reset CNVSTATE: If you determine that the CNVSTATE entry is corrupted or inconsistent, you may need to reset it. This can often be done through transaction codes like CNV_MBT or CNV_MBT_COCKPIT, depending on your specific migration scenario.
  
  
  Re-run the Migration: After resetting the CNVSTATE, you can attempt to re-run the migration process from the beginning or from the last successful phase.
