  Replace your_table and column_name with the actual table and column names.
  
  
  Remove or Merge Duplicates: Once you have identified the duplicates, you can either remove them or merge them based on your business logic. Ensure that you have backups before performing any delete operations.
  
  
  Data Validation: Implement data validation checks before migration to ensure that no duplicates exist in the source system.
  
  
  Re-run Migration: After resolving the duplicates, re-run the migration process to see if the error persists.
