What is the issue? Please be detailed.**
Updated new Version of the Form (Changing the API name of some of the questions) and published the new version of the form, without downloading the earlier Submission data.
After publishing the new version of the Form, we noticed that old submission data for the questions (for which we changed the API name) are blank.
Is there a way to retrieve the Submission data of the Old version Form from the ODK Central Server. We lost some critical data that was collected for last 2 days.
If a field is removed, it will not be included in exports by default. You can ask for all fields that were ever referenced in previous Form versions when you export data. Renaming a field is the same as removing a field and then adding a new one.
