How do I import form data a second time?

I have imported the forms and data from Adobe Forms Central.  However, I have modified one of the forms and would like to have all the data (additional data has been submitted since the first import) in JotForm when we start using it.  I do not want to lose the changes I have made to the form (don't want to risk another import overriding my changes).

Hi,

If changes were made to the imported form, updating the submission data may not work properly.  I have seen a few cases where something as simple as adding a single field to the new form caused the import update to fail.  You can give it a try to see if the update will work, your data will not be compromised during the process.  Using the update simply appends any new data to the current data set.  It does not overwrite it. 

A new import will not overwrite your current settings either.  It will create new forms with a new data set imported. 

You can always clone your form:

Then import the data from the original to the clone:

This is a bit tricky but should provide you with a backup of your current form and submissions just in case anything unforeseen does occur.
