Upgrade Overview

A major or minor upgrade requires a system redeployment. For information on how to upgrade the Teradata Database running in a virtual or public cloud environment, log in to Teradata Support at https://access.teradata.com and search for KCS001779.

For information on the level of customer support offered for a particular tier, see Teradata Database License Tiers.

Before an upgrade in a virtual or public cloud environment, the requirements related to the listed considerations are shown in the table.
Upgrade Consideration Requirement
Bundle Download Mechanism You obtain software upgrade bundles from Teradata Support at https://access.teradata.com.
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 including Server Management, PUT does not set a maintenance window, but does automatically reboot the system. Be sure to plan accordingly.
Post-Upgrade Image Creation You must create a new system 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.
