In 2017, Azure AD Domain Services became available to host in an Azure Resource Manager network. Since then, we have been able to build a more secure service using the Azure Resource Manager‘s modern capabilities. Because Azure Resource Manager deployments fully replace classic deployments, Azure AD DS classic virtual network deployments will be retired on March 1, 2023.
Impact
After March 1, 2023, your current Azure AD DS classic virtual network deployment will be removed, and all applications using Azure AD DS will no longer function.
Required Action
To avoid losing access to your managed domain, migrate Azure AD DS from your classic virtual network to an Azure Resource Manager virtual network before March 1, 2023.
Azure AD Domain Services classic VNET support will be retired on March 1, 2023.
