Support matrix for Hyper-V assessment

This article summarizes prerequisites and support requirements when you assess Hyper-V VMs for migration to Azure, using the Azure Migrate:Server Assessment tool. If you want to migrate Hyper-V VMs to Azure, review the migration support matrix.

To set up Hyper-V VM assessment, you create an Azure Migrate project, and add the Server Assessment tool to the project. After the tool is added, you deploy the Azure Migrate appliance. The appliance continuously discovers on-premises machines, and sends machine metadata and performance data to Azure. After discovery is complete, you gather discovered machines into groups, and run an assessment for a group.

Limitations

Support Details
Assessment limits You can discover and assess up to 35,000 Hyper-V VMs in a single Azure Migrate project.
Project limits You can create multiple projects in an Azure subscription. In addition to Hyper-V VMs, a project can include VMware VMs and physical servers, up to the assessment limits for each.
Discovery The Azure Migrate appliance can discover up to 5000 Hyper-V VMs.

The appliance can connect to up to 300 Hyper-V hosts.
Assessment You can add up to 35,000 machines in a single group.

You can assess up to 35,000 VMs in a single assessment for a group.

Hyper-V host requirements

Support Details
Hyper-V host The Hyper-V host can be standalone, or deployed in a cluster.

The Hyper-V host can run Windows Server 2019, Windows Server 2016, or Windows Server 2012 R2. Server core installation of Windows Server 2016 and Windows Server 2012 R2 are also supported.
You can't assess VMs located on Hyper-V hosts running Windows Server 2012.
Permissions You need Administrator permissions on the Hyper-V host.
If you don't want to assign Administrator permissions, create a local or domain user account, and add the user account to these groups- Remote Management Users, Hyper-V Administrators, and Performance Monitor Users.
PowerShell remoting PowerShell remoting must be enabled on each Hyper-V host.
Hyper-V Replica If you use Hyper-V Replica (or you have multiple VMs with the same VM identifiers), and you discover both the original and replicated VMs using Azure Migrate, the assessment generated by Azure Migrate might not be accurate.

VM requirements

Support Details
Operating system All operating systems can be assessed for migration.
Integration Services Hyper-V Integration Services must be running on VMs that you assess, in order to capture operating system information.

Azure Migrate appliance requirements

Azure Migrate uses the Azure Migrate appliance for discovery and assessment. You can deploy the appliance using a compressed Hyper-V VHD that you download from the portal, or using a PowerShell script.

Port access

The following table summarizes port requirements for assessment.

Device Connection
Appliance Inbound connections on TCP port 3389 to allow remote desktop connections to the appliance.

Inbound connections on port 44368 to remotely access the appliance management app using the URL: https://<appliance-ip-or-name>:44368

Outbound connections on ports 443 (HTTPS), to send discovery and performance metadata to Azure Migrate.
Hyper-V host/cluster Inbound connection on WinRM port 5985 (HTTP) to pull metadata and performance data for Hyper-V VMs using a Common Information Model (CIM) session.

Agent-based dependency analysis requirements

Dependency analysis helps you to identify dependencies between on-premises machines that you want to assess and migrate to Azure. The table summarizes the requirements for setting up agent-based dependency analysis. Hyper-V currently only supports agent-based dependency visualization.

Requirement Details
Before deployment You should have an Azure Migrate project in place, with the Server Assessment tool added to the project.

You deploy dependency visualization after setting up an Azure Migrate appliance to discover your on-premises machines

Learn how to create a project for the first time.
Learn how to add an assessment tool to an existing project.
Learn how to set up the Azure Migrate appliance for assessment of Hyper-V VMs.
Azure Government Dependency visualization isn't available in Azure Government.
Log Analytics Azure Migrate uses the Service Map solution in Azure Monitor logs for dependency visualization.

You associate a new or existing Log Analytics workspace with an Azure Migrate project. The workspace for an Azure Migrate project can't be modified after it's added.

The workspace must be in the same subscription as the Azure Migrate project.

The workspace must reside in the East US, Southeast Asia, or West Europe regions. Workspaces in other regions can't be associated with a project.

The workspace must be in a region in which Service Map is supported.

In Log Analytics, the workspace associated with Azure Migrate is tagged with the Migration Project key, and the project name.
Required agents On each machine you want to analyze, install the following agents:

The Microsoft Monitoring agent (MMA).
The Dependency agent.

If on-premises machines aren't connected to the internet, you need to download and install Log Analytics gateway on them.

Learn more about installing the Dependency agent and MMA.
Log Analytics workspace The workspace must be in the same subscription as the Azure Migrate project.

Azure Migrate supports workspaces residing in the East US, Southeast Asia, and West Europe regions.

The workspace must be in a region in which Service Map is supported.

The workspace for an Azure Migrate project can't be modified after it's added.
Costs The Service Map solution doesn't incur any charges for the first 180 days (from the day that you associate the Log Analytics workspace with the Azure Migrate project)/

After 180 days, standard Log Analytics charges will apply.

Using any solution other than Service Map in the associated Log Analytics workspace will incur standard charges for Log Analytics.

When the Azure Migrate project is deleted, the workspace is not deleted along with it. After deleting the project, Service Map usage isn't free, and each node will be charged as per the paid tier of Log Analytics workspace/

If you have projects that you created before Azure Migrate general availability (GA- 28 February 2018), you might have incurred additional Service Map charges. To ensure payment after 180 days only, we recommend that you create a new project, since existing workspaces before GA are still chargeable.
Management When you register agents to the workspace, you use the ID and key provided by the Azure Migrate project.

You can use the Log Analytics workspace outside Azure Migrate.

If you delete the associated Azure Migrate project, the workspace isn't deleted automatically. Delete it manually.

Don't delete the workspace created by Azure Migrate, unless you delete the Azure Migrate project. If you do, the dependency visualization functionality will not work as expected.
Internet connectivity If machines aren't connected to the internet, you need to install the Log Analytics gateway on them.
Azure Government Agent-based dependency analysis isn't supported.
