When you upgrade PowerDesigner, all modules installed on your machine are upgraded, including the repository. You cannot upgrade the repository through a repository proxy connection. You must use a direct ODBC connection instead.
Always back up your repository database before upgrading it.
The first time you connect to the repository after upgrading PowerDesigner, you are asked to upgrade the database. You do not have to have installed all the PowerDesigner modules to upgrade the repository database. For example, if you have the Conceptual Data Model installed on your machine, the CDM part of the database is upgraded together with any parts shared by other modules. If you do not have the Object Oriented Model installed on your machine, that part of the database will not be upgraded. The next user of the database that has installed the OOM will upgrade that part of the database upon connection, and so on.
All clients using a particular repository database must upgrade simultaneously in order to continue to connect to it.
If you created your repository database with Microsoft SQL Server or Sybase ASE before PowerDesigner version 15.0, we recommend that you select the Rebuild clustered indexes check box in the Repository Update Script dialog box when upgrading your repository. Rebuilding cluster indexes improves repository performance, particularly for document check out.
If you do not select this option at upgrade time, or if you use a direct Microsoft SQL Server or Sybase ASE repository connection, you can select at any time to perform the rebuild.
In case of upgrade failure due to network or permission problems, or insufficient disk space, you should restore the repository database from your backup version and retry an upgrade when problems are solved.
If the upgrade fails because of the data in your database, then you should contact technical support for assistance.
