|Bundle Download Mechanism||You obtain software upgrade bundles from Teradata at Your Service, which uses Akamai for the download process. If you are a new Akamai user, you are prompted to complete additional steps related to Akamai setup when first downloading an upgrade bundle.|
|Operating System Updates||Because the operating system software bundle includes both important security updates and the latest version of the utility used to upgrade Teradata components (PUT), you must download this bundle whenever upgrading other Teradata components with the exception of Server Management, for which the required updates are included in the image itself.|
|Outage Preparation||When upgrading the operating system and Teradata components other than Server Management, PUT automatically opens a maintenance window and reboots the system. The Server Management upgrade likewise results in a reboot of that component. Be sure to plan accordingly for these events.|
|Post-Upgrade Image Creation||You must create a new restore image after a software upgrade. If you do not create this image, the software on the recovered instance will not match, and the database cannot start if a node failure occurs.|
