I'm taking over a form that was created by a previous webmaster and have not used Formidable Forms before.  I have been asked to change a number of fields to different field types ie a dropdown to a Time field, a number field to a toggle field etc.  Is there a way to do this without losing the data submitted from the original field's submissions.  For instance can data be transferred to the new field so we don't loose previous data.  This form has thousands of entries and the data is pulled into reports so we can't lose previously submitted data. Thank you in advance.
