Retirement: All Azure Automation jobs running on Agent-based Hybrid Worker will be stopped from 1 April 2025

**Starting April 1, 2025,** all jobs running on agent-based User Hybrid Runbook Worker will be stopped. Azure Automation Agent-based User Hybrid Worker([Windows](https://docs.microsoft.com/en-us/azure/automation/automation-windows-hrw-install) & [Linux](https://docs.microsoft.com/en-us/azure/automation/automation-linux-hrw-install)) retired on**August 31, 2024, and is no longer supported** **.** It poses a potential Security risk since Agent-based Hybrid Worker has not been getting any Security fixes post-retirement. Hence, it is strongly recommended that you move _to_ [extension-based User Hybrid Runbook Worker (Windows & Linux)](https://docs.microsoft.com/en-us/azure/automation/extension-based-hybrid-runbook-worker-install?tabs=windows) _for executing Hybrid jobs._ _Key benefits of new approach:_ \- Enhanced security posture for your VMs through access control using system-assigned managed identities, instead of self-managed certificates \- Improved operational productivity for keeping the workers up to date, using automatic upgrades and at-scale management of the VMs \- Simplified installation of extension while eliminating the need to install Log Analytics agent. Follow the [instructions](https://learn.microsoft.com/en-us/azure/automation/migrate-existing-agent-based-hybrid-worker-to-extension-based-workers?tabs=bicep-template%2Cwin-hrw)to migrate your agent-based User Hybrid Runbook Workers to extension-based Hybrid Workers before April 1, 2025\.
