Migrate to Azure Cloud Services (extended support) using PowerShell

  • Artikkeli

These steps show you how to use Azure PowerShell commands to migrate from Cloud Services (classic) to Cloud Services (extended support).

Plan for migration

Planning is the most important step for a successful migration experience. Review the Cloud Services (extended support) overview and Planning for migration of IaaS resources from classic to Azure Resource Manager before beginning any migration steps.

Install the latest version of PowerShell

There are two main options to install Azure PowerShell: PowerShell Gallery or Web Platform Installer (WebPI). WebPI receives monthly updates. PowerShell Gallery receives updates on a continuous basis. This article is based on Azure PowerShell version 2.1.0.

For installation instructions, see How to install and configure Azure PowerShell.

Ensure Admin permissions

To perform this migration, you must be added as a coadministrator for the subscription in the Azure portal.

  1. Sign in to the Azure portal.
  2. On the Hub menu, select Subscription. If you don't see it, select All services.
  3. Find the appropriate subscription entry, and then look at the MY ROLE field. For a coadministrator, the value should be Account admin.

If you're not able to add a coadministrator, contact a service administrator or coadministrator for the subscription to get yourself added.

Register the classic provider and CloudService feature

First, start a PowerShell prompt. For migration, set up your environment for both classic and Resource Manager.

Sign in to your account for the Resource Manager model.

Connect-AzAccount

Get the available subscriptions by using the following command:

Get-AzSubscription | Sort Name | Select Name

Set your Azure subscription for the current session. This example sets the default subscription name to My Azure Subscription. Replace the example subscription name with your own.

Select-AzSubscription –SubscriptionName "My Azure Subscription"

Register with the migration resource provider by using the following command:

Register-AzResourceProvider -ProviderNamespace Microsoft.ClassicInfrastructureMigrate

Note

Registration is a one-time step, but you must do it once before you attempt migration. Without registering, you see the following error message:

BadRequest : Subscription is not registered for migration.

Register the CloudServices feature for your subscription. The registrations may take several minutes to complete.

Register-AzProviderFeature -FeatureName CloudServices -ProviderNamespace Microsoft.Compute

Wait five minutes for the registration to finish.

Check the status of the classic provider approval by using the following command:

Get-AzResourceProvider -ProviderNamespace Microsoft.ClassicInfrastructureMigrate

Check the status of registration using the following command:

Get-AzProviderFeature -FeatureName CloudServices -ProviderNamespace Microsoft.Compute

Make sure that RegistrationState is Registered for both before you proceed.

Before switching to the classic deployment model, make sure that you have enough Azure Resource Manager vCPU quota in the Azure region of your current deployment or virtual network. You can use the following PowerShell command to check the current number of vCPUs you have in Azure Resource Manager. To learn more about vCPU quotas, see Limits and the Azure Resource Manager.

This example checks the availability in the West US region. Replace the example region name with your own.

Get-AzVMUsage -Location "West US"

Now, sign in to your account for the classic deployment model.

Add-AzureAccount

Get the available subscriptions by using the following command:

Get-AzureSubscription | Sort SubscriptionName | Select SubscriptionName

Set your Azure subscription for the current session. This example sets the default subscription to My Azure Subscription. Replace the example subscription name with your own.

Select-AzureSubscription –SubscriptionName "My Azure Subscription"

Migrate your Cloud Services

Before starting the migration, understand how the migration steps works and what each step does.

Note

All the operations described here are idempotent. If you have a problem other than an unsupported feature or a configuration error, we recommend that you retry the prepare, abort, or commit operation. The platform then tries the action again.

Option 1 - Migrate a Cloud Service not in a virtual network

Get the list of cloud services by using the following command. Then pick the cloud service that you want to migrate.

Get-AzureService | ft Servicename

Get the deployment name for the Cloud Service. In this example, the service name is My Service. Replace the example service name with your own service name.

$serviceName = "My Service"
$deployment = Get-AzureDeployment -ServiceName $serviceName
$deploymentName = $deployment.DeploymentName

First, validate that you can migrate the Cloud Service by using the following commands. The command displays any errors that block migration.

$validate = Move-AzureService -Validate -ServiceName $serviceName -DeploymentName $deploymentName -CreateNewVirtualNetwork
$validate.ValidationMessages

If validation is successful or has just warnings, you can move on to the Prepare step.

Move-AzureService -Prepare -ServiceName $serviceName -DeploymentName $deploymentName -CreateNewVirtualNetwork

Check the configuration for the prepared Cloud Service (extended support) by using either Azure PowerShell or the Azure portal. If you're not ready for migration and you want to go back to the old state, abort the migration.

Move-AzureService -Abort -ServiceName $serviceName -DeploymentName $deploymentName

If you're ready to complete the migration, commit the migration

Move-AzureService -Commit -ServiceName $serviceName -DeploymentName $deploymentName

Option 2 - Migrate a Cloud Service in a virtual network

To migrate a Cloud Service in a virtual network, you migrate the virtual network. The Cloud Service automatically migrates with the virtual network.

Note

The virtual network name might be different from what is shown in the new portal. The new Azure portal displays the name as [vnet-name], but the actual virtual network name is of type Group [resource-group-name] [vnet-name]. Before you start the migration, look up the actual virtual network name by using the command Get-AzureVnetSite | Select -Property Name or view it in the old Azure portal.

This example sets the virtual network name to myVnet. Replace the example virtual network name with your own.

$vnetName = "myVnet"

First, validate that you can migrate the virtual network by using the following command:

Move-AzureVirtualNetwork -Validate -VirtualNetworkName $vnetName

The following command displays any warnings and errors that block migration. If validation is successful, you can proceed with the following Prepare step:

Move-AzureVirtualNetwork -Prepare -VirtualNetworkName $vnetName

Check the configuration for the prepared Cloud Service (extended support) by using either Azure PowerShell or the Azure portal. If you're not ready for migration and you want to go back to the old state, use the following command:

Move-AzureVirtualNetwork -Abort -VirtualNetworkName $vnetName

If the prepared configuration looks good, you can move forward and commit the resources by using the following command:

Move-AzureVirtualNetwork -Commit -VirtualNetworkName $vnetName
