Values collected in prior versions of OpenClinica should be stored in the MM/DD/YYYY format.  If the data is stored in a different format, the values will not be updated and will remain as they are.  A separate script will need to be created to identify and update these values.

For all partial dates stored in MM/DD/YYYY, a liquibase script will convert the values to conform to the ISO 8601 standard date format, YYYY-MM-DD.
