如何将同一云服务下的虚拟机从经典部署模型迁移到 Azure Resource Manager

适用场景

用户希望将特定云服务下的所有虚拟机从经典部署模型(以下简称：ASM)迁移到 Azure Resource Manager(以下简称：ARM)。

Note

如果云服务下使用 VNET 也希望将虚拟机从 ASM 模式迁移到 ARM 模式，您可以参考这篇文章：如何将同一个 VNET 下的虚拟机从 ASM 迁移到 ARM 上

解决方案

首先，我们登陆到需要迁移的虚拟机所在的订阅下，注册迁移服务：

PowerShell复制

#登陆到需要迁移的虚拟机所在的订阅下PS C:\windows\system32>Login-AzureRmAccount–Environment AzureChinaCloudEnvironment          : AzureChinaCloudAccount              : [e-mail]              :xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxSubscriptionId        :xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxSubscriptionName      : <订阅名称>CurrentStorageAccount :#如果您需要迁移某个特定订阅下的虚拟机，需要手动进行指定PS C:\windows\system32>Select-AzureRmSubscription–SubscriptionName"<订阅名称>"#注册迁移服务PS C:\windows\system32>Register-AzureRmResourceProvider-ProviderNamespaceMicrosoft.ClassicInfrastructureMigrate#迁移服务注册一般需要 5 分钟左右，您可以通过下述命令查看完成情况，PS C:\windows\system32>Get-AzureRmResourceProvider-ProviderNamespaceMicrosoft.ClassicInfrastructureMigrateProviderNamespace : Microsoft.ClassicInfrastructureMigrateRegistrationState : RegisteredResourceTypes    : {classicInfrastructureResources}Locations        : {China North, China East}#最后登陆到经典模式中需要迁移的虚拟机所在订阅下PS C:\windows\system32>Add-AzureAccount-EnvironmentAzureChinaCloudId                                Type Subscriptions                        [e-mail] Userxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx }#如果您需要迁移某个特定订阅下的虚拟机，需要手动进行指定Select-AzureSubscription–SubscriptionName"<订阅名称>"

Note

注册迁移服务为一次性操作，注册完成后以后迁移时无需再次注册，但是如果您在未注册前尝试迁移，会收到报错说该订阅未注册迁移服务。

检查 ARM 模式下您订阅里的配额，确保需要迁移的虚拟机有足够的配额可以使用：

PowerShell复制

#您可以根据虚拟机所在的区域选择 China North 或者 China EastPS C:\windows\system32>Get-AzureRmVMUsage-Location"China East"Name                            Current Value Limit  Unit--------------------------Availability Sets22000CountTotal Regional Cores39100CountVirtual Machines1710000CountVirtual Machine Scale Sets12000CountStandard Dv2 Family Cores4100CountStandard FS Family Cores16100CountStandard A0-A7 Family Cores11100CountStandard D Family Cores1100CountStandard Av2 Family Cores2100CountStandard DSv2 Family Cores4100CountStandard DS Family Cores1100CountBasic A Family Cores0100CountStandard A8-A11 Family Cores0100CountStandard G Family Cores0100CountStandard GS Family Cores0100CountStandard F Family Cores0100CountStandard NV Family Cores00CountStandard NC Family Cores00CountStandard H Family Cores00CountStandard LS Family Cores0100CountStandard Dv2 Promo Family Cores0100CountStandard DSv2 Promo Family Cores0100CountStandard MS Family Cores00CountStandard Dv3 Family Cores0100CountStandard DSv3 Family Cores0100CountStandard Ev3 Family Cores0100CountStandard ESv3 Family Cores0100CountStandard Storage Managed Disks010000CountPremium Storage Managed Disks010000Count

将同一个云服务下的虚拟机从 ASM 迁移到 ARM 上:

PowerShell复制

#查询云服务并找出您想要迁移的云服务，此处以 1vnet2cs02 为例PS C:\windows\system32>Get-AzureService|ft ServicenameServiceName-----------1vent2cs041vnet2cs011vnet2cs021vnet2cs03#获取部署名称PS C:\windows\system32>$serviceName="1vnet2cs02"PS C:\windows\system32>$deployment=Get-AzureDeployment-ServiceName$serviceNamePS C:\windows\system32>$deploymentName=$deployment.DeploymentNameResult            : Validation Passed with warnings. Please see ValidationMessages objectfora list of resources                    that will be migrated and additional detail on the warnings.ValidationMessages : {test4as, test01, test01, test01...}

选择 1：将 VM 迁移到一个新建的虚拟网络中:

PowerShell复制

#验证云服务PS C:\windows\system32>Move-AzureService-Validate-ServiceName$serviceName` -DeploymentName$deploymentName-CreateNewVirtualNetworkOperationId        :119a8709-4160-4122-859d-a1bc2dc8c603Result            : Validation Passed.

选择 2：将 VM 迁移到一个已有的虚拟网络中:

PowerShell复制

#准备已有虚拟网络的相关信息PS C:\windows\system32>$existingVnetRGName="<虚拟网络所在的资源组名称>"PS C:\windows\system32>$vnetName="<虚拟网络名称>"PS C:\windows\system32>$subnetName="<子网名称>"#验证云服务PS C:\windows\system32>Move-AzureService-Validate-ServiceName$serviceName`>>-DeploymentName$deploymentName-UseExistingVirtualNetwork-VirtualNetworkResourceGroupName$existingVnetRGName-VirtualNetworkName$vnetName-SubnetName$subnetName#上述验证通过后接下来执行迁移准备操作PS C:\windows\system32>Move-AzureService-Prepare-ServiceName$serviceName-DeploymentName$deploymentName`>>-UseExistingVirtualNetwork-VirtualNetworkResourceGroupName$existingVnetRGName`>>-VirtualNetworkName$vnetName-SubnetName$subnetNameOperationDescription OperationId                          OperationStatus----------------------------------------------Move-AzureService9c9e01a6-183e-4884-b51d-04f25112934e Succeeded#如果迁移准备步骤操作成功，那么可以执行下述命令来生效迁移操作PS C:\windows\system32>Move-AzureService-Commit-ServiceName$serviceName-DeploymentName$deploymentNameOperationDescription OperationId                          OperationStatus----------------------------------------------Move-AzureServicec803cc0d-1446-4922-bcb1-af1330828c69 Succeeded

迁移虚拟机所在的存储账号:

PowerShell复制

#检查存储账号下是否有未被迁移的虚拟机的 VHD 存在PS C:\windows\system32>$storageAccountName="<存储账号名称>"PS C:\windows\system32>Get-AzureDisk|where-Object{$_.MediaLink.Host.Contains($storageAccountName)} |Select-Object-ExpandPropertyAttachedTo-Property`>>  DiskName |Format-List-PropertyRoleName, DiskName#检查存储账号下是否有已分离的虚拟机磁盘，如有需要进行删除，如果您仍然需要这些磁盘可以将其复制到其他存储账号中PS C:\windows\system32>Get-AzureDisk|where-Object{$_.MediaLink.Host.Contains($storageAccountName)} |Where-Object-PropertyAttachedTo-EQ$null|Format-List-Property DiskNameDiskName : disktest#删除磁盘PS C:\windows\system32>Remove-AzureDisk-DiskName"disktest"OperationDescription OperationId                          OperationStatus----------------------------------------------Remove-AzureDisk9661659d-3bcf-4e6e-bdc4-cce7c8d7a1e0 Succeeded#删除存储账号中 OS 盘和数据盘中的虚拟机镜像PS C:\windows\system32>Get-AzureVmImage|Where-Object{$_.OSDiskConfiguration.MediaLink-ne$null-and$_.OSDiskConfiguration.MediaLink.Host.Contains($storageAccountName)`>>                            } |Select-Object-PropertyImageName, ImageLabelImageName                  ImageLabel-------------------captureTest-20160902-436096PS C:\windows\system32>Get-AzureVmImage|Where-Object{$_.DataDiskConfigurations-ne$null`>>-and($_.DataDiskConfigurations |Where-Object{$_.MediaLink-ne$null-and$_.MediaLink.Host.Contains($storageAccountName)}).Count-gt0`>>                                    } |Select-Object-PropertyImageName, ImageLabelPS C:\windows\system32>Remove-AzureVMImage-ImageName"captureTest-20160902-436096"OperationDescription OperationId                          OperationStatus----------------------------------------------Remove-AzureVMImageb8f1c164-147a-4d98-9805-432dcd3b7105 Succeeded
