Upgrade a Fleet

Objective

This guide provides instructions on how to upgrade a Volterra Fleet of sites using the guided wizard in VoltConsole. See Fleet for more information.

A Fleet is used to perform upgrades to the Volterra Site software and operating system software. You can also use Fleet to add or delete devices such as network interfaces or storage devices to the Fleet of sites. This document covers information on how to perform software upgrades using the Volterra Fleet.

Fleet upgrades are not supported for clouds sites, such as AWS VPC, AWS TGW, Azure VNET, GCP Credentials, or VoltStack Sites.

Note: The outcome of attempts to perform upgrades using the Fleet are dependent on the Site Software Version Override setting of the Site that is part of the Fleet. The following list describes the behavior:

  • If the set value of override is Site Version Overrides, then the version set in Site always takes precedence.
  • If the set value of override is New Version Overrides, then the newer version among Site and Fleet takes precedence.
  • If the set value of override is Fleet Version Overrides, then the version set in Fleet always takes precedence.

Prerequisites
