Upgrading a QCD
A QCD created prior to the latest Teradata Database release must be upgraded before it can be used.
Note: The following limitations apply when upgrading an existing QCD or reverting to an earlier version:
To upgrade a QCD
Before beginning, note the following:
1 Click Tools>Control Center.
The Control Center dialog box appears, and the Manage QCD tab is selected by default.
2 Click Upgrade/Revert QCF Version.
The Upgrade/Revert dialog box appears.
3 In the QCD Name box, do one of the following:
i Click List QCDs.
i Click List QCDs.ii Select a QCD from the QCD Name list.
The selected QCF version appears in the Present Version box.
4 In the Intended Version box, select the version to change to.
5 Click OK to begin the conversion.
Note: An upgrade can be aborted or canceled, provided the upgrade process has not been completed. Depending on the point at which an upgrade is aborted, a prompt appears and displays an option to rollback the upgrade process. At this point, the upgrade can be rolled back or canceled. Rolling back the upgrade process undoes all upgrade operations; that is, the QCD is restored to its pre‑upgrade state. Canceling the upgrade leaves the upgrade process unfinished. The partially upgraded QCD is not a valid QCD. To complete the upgrade, the QCD name must be re‑entered in the QCD Name box and the process restarted from the step where the rollback was canceled.
