  Adjust Mapping: If the duplicates are a result of incorrect mapping, review and adjust the mapping configuration in the migration tool to ensure that it correctly handles the data.
  
  
  Use Data Quality Tools: Consider using data quality tools to validate and cleanse the data before migration. This can help prevent duplicates from being introduced into the target system.
