Preserving data after re-deployment

kobocollect

#1

Can it be possible that edits made to the deployed version must not entirely affect data collected prior. For example, Because of time and budgetary constraints, I am forced to change eg the logic of a template after users would have discovered bugs. If I corrected those bugs, data collected after I have re-deployed becomes un-usable.

Is there a way for the Kobo to still preserve data collected before any corrections?
