Before starting, open a maintenance window to see the status of the Teradata components during the upgrade process, including data, summary alerts, and reports. For more information on using maintenance windows, see Teradata® Server Management Web Services User Guide.
After initiation, the upgrade process is completely non-interactive. During the upgrade, PUT reboots the system.
When performing a major upgrade, you must instead redeploy the system. See Installing and Configuring Teradata Database on VMware.
- Download the required upgrade bundles. Because the operating system upgrade bundle includes both important security updates and the latest version of PUT, you must upgrade the operating system whenever upgrading other Teradata components in a virtual or public cloud environment.
- Log on as user root to the system where the component you are upgrading is installed.
- If the following directory does not exist, create it: /var/opt/teradata/swupgrade-source
- Transfer the downloaded upgrade bundles to /var/opt/teradata/swupgrade-source.
- Change to the PUT bin directory: /opt/teradata/TDput/bin
- Run the swupgrade -U command: /opt/teradata/TDput/bin/swupgrade -U The upgrade process begins, displaying progress messages on screen until the system reboots.
Log back on to the system and run the command to display the log as the upgrade completes:
tail -f /var/opt/teradata/TDput/fileservice/logs/swupgrade.log
PUT displays the following to indicate upgrade completion:
Operation completed with exit status 0 :: :: Output for this script (swupgrade) can be found at /var/opt/teradata/TDput/fileservice/logs/swupgrade.log
- Press Ctrl+c to exit the tail command.
- Confirm the upgrade version on the system.
