Important: Before upgrading your QueryGrid 2.x system to QueryGrid 3.0 on Teradata VantageCore, you must create a change request on https://support.teradata.com to receive special 3.0 upgrade instructions. For more information, go to https://support.teradata.com and search for KB0048892.

The following additional requirements are necessary when upgrading to QueryGrid 3.0:

  • The system must be running QueryGrid 2.15 or later.
  • You must first upgrade the system to QueryGrid 3.0 before upgrading to later QueryGrid 3.x versions.

    Once your system is upgraded to QueryGrid 3.0, any subsequent 3.x upgrades can follow the upgrade instructions in this section.

Upgrade overview

The steps for upgrading QueryGrid Manager are similar to those for installing it, whereas the upgrade processes for connectors, fabrics, and node software differs from the installation process.
If upgrading a site with a full Vantage stack and analytical nodes, open an incident with the QueryGrid GSO team for consultation before upgrading.
For connectors and fabrics, the upgrade process allows you to test new versions before deploying the new versions to production. Upgrades to these components are considered configuration changes. For each configuration, three versions can co-exist:
  • Active
  • Pending
  • Previous

This protocol provides for pushing changes to all systems before implementation, allowing you to test new connectors and fabrics on production deployments without affecting production workloads.

You can also update links, networks, and communication policies. Like connector and fabric upgrades, such updates are considered configuration changes and are subject to the same version and deployment protocol.

The upgrade process for QueryGrid node software differs from the installation process, with the final deployment steps being handled automatically by the pre-existing version of the software.
