Migrating to the New CONNX CDD Format
The CONNX CDD has been converted to a new format in order to increase performance levels. If you are currently running a version of CONNX that is earlier than 10, you may find that you need to convert your CDDs to the new format (created in and added to version 9.0) for consistency and security.
To convert your CDDs to the new CONNX CDD format, open the CONNX Data Dictionary Manager, select a CDD, then Save the CDD.
If you do not wish to change your CDD format, Software AG recommends that you create a backup copy of your production CDD, and then create a copy that can be used by CONNX. For identification purposes, the file extension on converted CONNX CDDs is .vn9.
