Veeam ONE - 12.1 Upgrade

Veeam released the 12.1 update back in November 2023, and with it comes upgrades to most components, including Veeam ONE. Today, I will walk through the upgrade process in my homelab to update my current Veeam ONE server from 12.0 to 12.1. Many enhancements came with Veeam ONE 12.1, including some of the following -

Veeam Threat Center
Unified Analytics-Driven Approach to Data Management
- Integrated Dashboards
Alarm Lifecycle
- ServiceNow Incident Management Integration
- Syslog SIEM Integration
Elevating Veeam Data Platform Security
- Backup Security and Compliance: Instant Insights for Robust Data Protection
- Malware Detection: Pinpoint, Protect, Prevail

A full list of the enhancements in Veeam ONE 12.1 can be found here - Veeam ONE 12.1 - What's New.

***NOTE - You must download the Veeam ONE 12.1 ISO file to follow the steps.***

The following steps are required to upgrade Veeam ONE to 12.1 -
