New
We are attempting to "Repoint" old class data to new class data to save disk space and data redundancy across multiple tables. This works to a point. In essence the two classes are sharing the same data / Index / stream globals. But if an ID in the Old_Class is opened, a property is modified, and saved the property that is in the New_Class (but not in the Old_Class) is NULLed / blanked.
Simplified explanation of data and what’s occurring.
