You can modify the type or details of an external class connection. The type of connection can be changed between Local or Linked Server, ODBC Connection, and Unity Script.
Modifying the external class connection can prove especially useful when migrating to a cloud-based solution. Unity Script classes can be used to access APIs and increase the system performance.
It is not possible to change the connection type to Unity Script if the existing external class has composite unique keys.
The Modify External Class Connection wizard will guide you through class configuration. All data previously configured within the class, such as history or relationships with other tables, remains intact.
After conversion, attributes and external data column names need to be configured for the class to work properly.
If you wish to restore the previous connection type, Unity Scripts and data column names are not removed during class type conversion. The class type can be restored to its previous state without any loss.
