To change the name of an <<Ispec>> class and retain your existing data, you cannot simply change the name and then reorganize. You must perform the following:
Declare a new <<Ispec>> class in your Specification, then build the application with the Retain Existing Database Segment configuration property set to True.
Move the data from your original <<Ispec>> class into the new one, by writing and using a Report.
Delete the original <<Ispec>> class, then rebuild your application with the Retain Existing Database Segment configuration property set to True.
