Step 5: Map Fields

The system suggests automatic mappings based on field name similarity:

Tips for Successful Migration

+--------------------------------+----------------------------------+
|  DO                            |  DON'T                           |
+--------------------------------+----------------------------------+
|  Preview sample records first  |  Import without validation       |
|  Save templates for reuse      |  Recreate mappings each time     |
|  Validate before importing     |  Skip the preview step           |
|  Start with small test batch   |  Import full dataset first       |
|  Document your mappings        |  Rely on memory                  |
|  Check encoding before upload  |  Assume UTF-8 encoding           |
|  Back up before large imports  |  Import without backup           |
