Upgrading SAP Business Content has no effect on the BW objects that you already use productively, since only the D version is overwritten.
The following graphic shows how SAP Business Content objects are used in a customer system with a double delivery:

In the SAP Content delivery system, BW objects are copied automatically into the D version when you activate them.
There are two logical transport objects for each BW object: An A object and a D object. In accordance with the system settings, the system writes the suitable TLOGO object to the transport request. When a Content system is involved, the system chooses the D TLOGO object.

You can find additional information on
transport-relevant metadata object types in the Business Information Warehouse

Metadata Object Types.

In the customer system, changes to the BW objects are saved in the active version. However, they are not automatically copied to the D version when you activate them.
