to upgrade to. Alternatively, you can use the Browse button to specify the location of the
DAC package. When the DAC package is selected, you can verify the DAC details, such as
the application name, version number, and description in the read-only text boxes.
IMPORTANT Ensure that the DAC package and the original DAC have the same name.
7. When invoked, the Detect Change page starts off by displaying a progress bar while the
wizard veries differences between the current schema of the database and the objects
in the DAC denition. The change detection results indicate whether the database objects
have changed or remain the same. If the database has changed, you are warned that
there may be data loss if you proceed with the upgrade, as illustrated in Figure 3-11.
Select the Proceed Despite Possible Loss Of Changes check box, and click Next to continue.
