 # Update Management overview
 
+> [!Important]
+> - Automation Update management relies on [Log Analytics agent](../../azure-monitor/agents/log-analytics-agent.md) (aka MMA agent), which is on a deprecation path and won’t be supported after **August 31, 2024**. [Update management center (Preview)](../../update-center/overview.md) (UMC) is the v2 version of Automation Update management and the future of Update management in Azure. UMC is a native service in Azure and does not rely on [Log Analytics agent](../../azure-monitor/agents/log-analytics-agent.md) or [Azure Monitor agent](../../azure-monitor/agents/agents-overview.md).

For customers using Automation Update management, we recommend continuing to use the Log Analytics agent and **NOT** migrate to Azure Monitoring agent until migration guidance is provided for Update management or else Automation Update management will not work. Also, the Log Analytics agent would not be deprecated before moving all Automation Update management customers to UMC.

 You can use Update Management in Azure Automation to manage operating system updates for your Windows and Linux virtual machines in Azure, physical or VMs in on-premises environments, and in other cloud environments. You can quickly assess the status of available updates and manage the process of installing required updates for your machines reporting to Update Management. 
 
 As a service provider, you may have onboarded multiple customer tenants to [Azure Lighthouse](../../lighthouse/overview.md). Update Management can be used to assess and schedule update deployments to machines in multiple subscriptions in the same Azure Active Directory (Azure AD) tenant, or across tenants using Azure Lighthouse.
