Azure Migrate support matrix

  • Article

You can use the Azure Migrate service to assess and migrate servers to the Microsoft Azure cloud. This article summarizes general support settings and limitations for Azure Migrate scenarios and deployments.

Supported assessment/migration scenarios

The table summarizes supported discovery, assessment, and migration scenarios.

Deployment Details
Discovery You can discover server metadata, and dynamic performance data.
Software inventory You can discover apps, roles, and features running on VMware VMs. Currently this feature is limited to discovery only. Assessment is currently at the server level. We don't yet offer app, role, or feature-based assessments.
Assessment Assess on-premises workloads and data running on VMware VMs, Hyper-V VMs, and physical servers. Assess using Azure Migrate: Discovery and assessment, Microsoft Data Migration Assistant (DMA), as well as other tools and ISV offerings.
Migration Migrate workloads and data running on physical servers, VMware VMs, Hyper-V VMs, physical servers, and cloud-based VMS to Azure. Migrate using the Migration and modernization tool and Azure Database Migration Service (DMS), and well as other tools and ISV offerings.

Project

Support Details
Subscription Can have multiple projects within a subscription.
Azure permissions Users need Contributor or Owner permissions in the subscription to create a project.
VMware VMs Assess up to 35,000 VMware VMs in a single project.
Hyper-V VMs Assess up to 35,000 Hyper-V VMs in a single project.

A project can include both VMware VMs and Hyper-V VMs, up to the assessment limits.

Azure permissions

For Azure Migrate to work with Azure you need these permissions before you start assessing and migrating servers.

Task Permissions Details
Create a project Your Azure account needs permissions to create a project. Set up for VMware, Hyper-V, or physical servers.
Register the Azure Migrate appliance Azure Migrate uses a lightweight Azure Migrate appliance to discover and assess servers with Azure Migrate: Discovery and assessment, and to run agentless migration of VMware VMs with the Migration and modernization tool. This appliance discovers servers, and sends metadata and performance data to Azure Migrate.

During registration, register providers (Microsoft.OffAzure, Microsoft.Migrate, and Microsoft.KeyVault) are registered with the subscription chosen in the appliance, so that the subscription works with the resource provider. To register, you need Contributor or Owner access on the subscription.

VMware-During onboarding, Azure Migrate creates two Microsoft Entra apps. The first app communicates between the appliance agents and the Azure Migrate service. The app doesn't have permissions to make Azure resource management calls or have Azure RBAC access for resources. The second app accesses an Azure Key Vault created in the user subscription for agentless VMware migration only. In agentless migration, Azure Migrate creates a Key Vault to manage access keys to the replication storage account in your subscription. It has Azure RBAC access on the Azure Key Vault (in the customer tenant) when discovery is initiated from the appliance.

Hyper-V-During onboarding. Azure Migrate creates one Microsoft Entra app. The app communicates between the appliance agents and the Azure Migrate service. The app doesn't have permissions to make Azure resource management calls or have Azure RBAC access for resources.		 Set up for VMware, Hyper-V, or physical servers.
Create a key vault for VMware agentless migration To migrate VMware VMs with agentless Migration and modernization, Azure Migrate creates a Key Vault to manage access keys to the replication storage account in your subscription. To create the vault, you set permissions (Owner, or Contributor and User Access Administrator) on the resource group where the project resides. Set up permissions.

Supported geographies

Public cloud

You can create a project in many geographies in the public cloud.

  • Although you can only create projects in these geographies, you can assess or migrate servers for other target locations.
  • The project geography is only used to store the discovered metadata.
  • When you create a project, you select a geography. The project and related resources are created in one of the regions in the geography. The region is allocated by the Azure Migrate service. Azure Migrate does not move or store customer data outside of the region allocated.
Geography Metadata storage location
Africa South Africa or North Africa
Asia Pacific East Asia
Australia Australia East or Australia Southeast
Brazil Brazil South
Canada Canada Central or Canada East
Europe North Europe or West Europe
France France Central
Germany Germany West Central
India Central India or South India
Italy North Italy
Japan Japan East or Japan West
Jio India Jio India West
Korea Korea Central
Norway Norway East
Sweden Sweden Central
Switzerland Switzerland North
United Arab Emirates UAE North
United Kingdom UK South or UK West
United States Central US or West US 2

Note

For Switzerland geography, Switzerland West is only available for REST API users and need an approved subscription.

Azure Migrate versions

There are two versions of the Azure Migrate service:

  • Current version: Using this version you can create new projects, discover on-premises assesses, and orchestrate assessments and migrations. Learn more.
  • Previous version: For customer using, the previous version of Azure Migrate (only assessment of on-premises VMware VMs was supported), you should now use the current version. In the previous version, you can't create new projects or perform new discoveries.
