Upgrade non finalized survey

1. What is the problem? Be very detailed.
We have a large form and, due to a desing mistake, if certain choice is selected the form cannot be finalized. We want to upgrade the corrected form so the user can upgrade it is his device allowing him to finalize and send the form. If that's not possible, should we use briefcase to send the data?

2. What app or server are you using and on what device and operating system? Include version numbers.

ODK Collect 1.28.4
ODK Central 1.0

3. What you have you tried to fix the problem?

We have been trying to replicate the error aun upgrade the corrected form, but the edited survey seems to mantain the old form.

4. What steps can we take to reproduce the problem?

5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.

You can download an updated version of your form here you can read how to do that Making changes to existing form
The thing is that if you already have your old form filled and you download a newer version with bumped version number then that already saved form will be opened (during editing) using the old version of your form as described in the doc:

Both versions of the form will exist in the device of the user but only the newer one will be visible on the list. Thanks to that the user will be able to edit forms he has started using the older version and upload them to the server, but new forms will be started using the newest available form version.

so you would need to fill it again in order to use the new one.

You can also try replacing what is described below in the same doc.

Please read the doc everything is described very well there.

Thank you Grzesiek2010. We missunderstood the documentation.

Finally we've uploaded the surveys with ODK Briefcase.
