Windows Server 2012 and Windows Server 2012 R2 are approaching their end-of-life date on October 10, 2023. After this critical date, servers running these versions will no longer be eligible for essential security updates, non-security updates, bug fixes, or technical support from Microsoft. Continuing to operate on unsupported software exposes your systems to potential security vulnerabilities and compliance risks. If upgrading to a newer version of Windows Server isn’t immediately feasible, Microsoft offers Extended Security Updates (ESUs) for a maximum of three years as a temporary solution. These ESUs are available at no cost on Azure or can be purchased for on-premises deployments.
To determine the specific lifecycle details for your Microsoft products, you can search the Microsoft Lifecycle Policy.
Option 1: Migrate to Azure and Gain Free Extended Security Updates
For organizations seeking a robust and cost-effective path forward, migrating your applications and databases to Azure is a highly recommended solution. By moving to Azure services such as Azure VMware Solution, Azure Stack HCI, Virtual Machines, or Dedicated Host, you become eligible for free Extended Security Updates for up to three years post the end-of-support date. This provides a significant window to plan and execute a more comprehensive upgrade strategy while maintaining security compliance. Furthermore, the Azure Hybrid Benefit can be leveraged to optimize costs on Windows Server and SQL Server licenses when migrating to Azure.
Option 2: Upgrade to Windows Server 2022 or Purchase Extended Security Updates for On-Premises Deployments
If maintaining an on-premises infrastructure is a business requirement, you have two primary options. The first is to upgrade your servers to the latest Windows Server 2022. This ensures you are running on a fully supported and feature-rich platform with the latest security enhancements. Alternatively, if an immediate upgrade is not possible, you can purchase Extended Security Updates (ESUs) for Windows Server 2012. These ESUs provide security updates only, for a period of up to three years, renewable annually, extending until October 13, 2026. To streamline the deployment of purchased ESUs in on-premises environments and enhance your security posture, consider utilizing Azure Arc. Azure Arc enables automated ESU deployment and extends Azure security and governance capabilities to your on-premises infrastructure.
Take Action Before the Deadline
The end of life for Windows Server 2012 R2 is fast approaching. It is crucial to assess your current server infrastructure and decide on the best path forward for your organization. Whether it’s migrating to Azure to capitalize on free ESUs or upgrading your on-premises servers, proactive planning and execution are essential to ensure continued security and operational stability beyond the October 10, 2023, end-of-support date.
