replace data of record using Datamover

Hi all,

While doing batch load testing for a few of the custom process, I used to get the untouched data from production and then try to test it. For this, I usually export table A from prod and import it table A to dev instance using 'Replace data' in the data mover script.

Now in this sprint, as a part of development, we changed the structure of table A by adding 1 date field. So in this case how can I replace data from production data since 1 field is added in dev? The volume of data in record A is pretty big.
