Connection Management

Effective in version 9.5.0, the Data Integration Service identifies each connection by the connection ID. Therefore, you can rename a connection.
Previously, the Data Integration Service identified each connection by the connection name. You could not rename a connection.
If you upgrade to version 9.5.0, the upgrade process sets the connection ID for each connection to the connection name.
