Upgrade Guide with ISO and Template#

Introduction#

Before starting with this upgrade, please read the following notes related to upgrades from earlier versions of the software.

Normal operations will be interrupted during an upgrade. Perform the upgrade in a maintenance window. Refer to the type of upgrade for details on the upgrade duration.

Release 21.4 onwards - Product License Changes

From release 21.4 onwards, VOSS Automate allows for the registration and update of product licenses within the application. A licensing service is installed during installation or upgrade and a license token is associated with the platform on which it is installed.

Release 24.1 onwards - Virtual Machine and ESXi Version Compatibility, and AVX Support

Before starting your upgrade, ensure that the hardware version of each of your virtual machines (VMs) is at least version 11, compatible with ESXi 6.0 and up, and that your host CPU supports AVX (Advanced Vector Extensions).

A "check cluster" command in the Automate pre-upgrade steps checks for AVX support. To ensure that AVX support is added to the VMs, you'll need to upgrade the compatibility of the VM in vCenter.

Release 24.1 onwards - Microsoft Teams, Deprecation of Basic Authentication

Starting with Automate 24.1, Microsoft PowerShell must be set up for app (application) registration for authentication.
