  Check Field Lengths: Review the field definitions in the target system to understand the expected lengths. Ensure that the data being migrated adheres to these constraints.
  Data Cleansing: Before migration, cleanse the data to ensure that it meets the length requirements. This may involve truncating data, removing unnecessary characters, or splitting data into multiple fields if necessary.
  Adjust Mapping: If the mapping is incorrect, adjust it to ensure that the data is being placed in the correct fields with the appropriate lengths.
  Use Data Transformation Tools: Utilize data transformation tools or scripts to modify the data before migration to ensure compliance with length requirements.
  Testing: Conduct thorough testing with a subset of data to identify any other potential issues before performing a full migration.
