For a major or minor Teradata Database upgrade, decide the Teradata Database release you want to upgrade to by reviewing information about the features and requirements contained in the releases and the associated Teradata Tools and Utilities. Consult with your Teradata Solutions Architect for your overall Teradata Warehouse operation and with your CSR about any additional requirements for updating the hardware platform model(s), storage arrays, and other applications and processes running on your system.
For a maintenance or patch upgrade, you will only be updating your current Teradata Database release and will not need to choose a different target release.
