Microsoft has officially released Windows Admin Center (WAC) version 2511, delivering restored High Availability (HA), major backend fixes, security enhancements, and significant usability improvements across core management tools. In this article, we shall discuss “How to upgrade Windows Admin Center from v2411 to v2511”. Please, see how to deploy Veeam Recovery Orchestrator and Agents to VBR and VEM, and how to set up Windows Admin Centre on a Windows Server.

With this version, Administrators can once again deploy Windows Admin Centre in a failover cluster configuration, ensuring gateway resiliency and service continuity. The restored HA functionality works with the modernised gateway architecture introduced in previous releases, allowing organisations to maintain enterprise-grade availability without reverting to older builds.

Microsoft also improved silent installation support, enhancing command-line deployment options for automated and large-scale rollouts. This makes version 2511 particularly valuable for enterprises managing multiple gateways across environments.
