The MDS12 Defaults Conversion Upgrade utility does NOT modify any existing data in the existing 12 project MDS catalogue and specifications database.

The MDS12 application is supplied with an updated copy of the master MDS project containing the MDS catalogue and specifications. The range of MDS components and bore sizes stored in the master MDS project catalogue are fixed.

Caution: The master MDS project catalogue and associated specifications must NOT be modified by the client, as this would compromise the integrity of the MDS application.
