The column version in the KaleoDefinition is an Integer

The column version in the KaleoDefinitionVerison is a String

They store the same content but have different types. This generates issues during the upgrade process (see LPS-107785) and it makes harder to maintain the framework since we have to do conversions when dealing with these fields.
