A major or minor upgrade requires redeploying the system. For information on how to upgrade Vantage running in a virtual or public cloud environment, log in to https://support.teradata.com and search for KCS001779.
To upgrade, all customers have to purchase Vantage Limited Upgrade plan or Essential Success Tier.
Teradata recommends customers to contact Teradata Sales team and plan for migration from Vantage 1.x to Vantage 2.x.
|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. 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.|
