Import - Delete if exists

Import - Delete if exists

Hi!

I have downloaded some data from my application and made some changes en-masse because I changed the structure of my database. I now want to re-upload the downloaded file to the relevant form and update the data.

From what I have read, it looks like using the Migration Tool is the best option as it allows adding of data to Zoho Creator. However, I have been unsuccessful in updating the data as I cannot match based on the field that I would like to match upon. I only get an option to match based on ID. Is there a way to match based on another field?

Thanks
