What's new in Azure Migrate

  • Article

Azure Migrate helps you discover, assess, and migrate on-premises servers, apps, and data to the Azure cloud platform. This article summarizes new releases and features in Azure Migrate.

Update (April 2025)

  • General availability: Azure Migrate now supports a simplified experience through its upgraded version of the agent-based migration stack. This stack offers a streamlined experience for customers and is set to replace the classic experience over the next three years. Learn more.

  • Public preview: Azure Migrate supports application awareness to offer an enhanced and modernized user experience. This feature streamlines the discovery, assessment, and migration of on-premises applications and workloads to Azure. It streamlines and enhances the decision-making, planning, and migration workflow by identifying and evaluating the current state of your on-premises infrastructure.

  • Updated inventory view: Explore the inventory of discovered workloads across the infrastructure, data, and web tiers. Learn more.

  • Tags: Tags in Azure Migrate enhance analysis by enabling customers to group and visualize related resources based on specific properties. Learn more.

  • Enhanced dependency analysis: Use the new dependency analysis experience to identify application boundaries and group workloads accordingly. Learn more.

  • Application assessment: You can include constituent workloads, such as application servers, web apps, and databases. The assessment then evaluates all potential Azure target services for these workloads and provides a recommended migration path, along with cost and readiness details. Learn more.

  • Action Center: Azure Migrate now includes Action Center, which offers a centralized hub for users to view and manage all migration-related issues, pending actions, and jobs within a project. Learn more.

Update (February 2025)
