Submission in the cloud gone after updating the ODK form

Dear all

I started a survey a few months ago. Then we decided to add to the form some new names of the enumerators and new villages in the choice sheet we changed, the version of the form and uploaded the form to the server in the cloud, everything went well. But then we found out later that the submitted data uploaded to the server disappeared. Luckily we had downloaded the data already. But I am still wondering if we did something wrong or if this is inherent to ODK. If this is inherent to ODK then it should be addressed, because what we did is normal in surveys

your advice will be highly appreciated

Are you using ODK Aggregate?

Did you delete the old form before you updated to the new one?

That would explain everything.

When updating the version of a form definition, you should simply re-upload
the form -- do not delete the existing form first. The server will detect
that the form definition being uploaded has a newer version and will
replace the existing form definition with the new one.

If you do that, your existing data will be preserved.

Following the same. What do I need to do the the form if I add a new field in the survey page. Do I have to add the new field and change the version ID.... ? I am fraid I might loose the submissions present.

Adding a new field changes the underlying database structure and so you should create a different form with a different form ID rather than trying to add a field to an existing form.

Thanks Yaw, This will be ok.
