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)。
注意
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：
#登陆到需要迁移的虚拟机所在的订阅下 PS C:\windows\system32> Login-AzureRmAccount –Environment AzureChinaCloud Environment : AzureChinaCloud Account : XXX@mcpod.partner.onmschina.cn TenantId : xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx SubscriptionId : xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx SubscriptionName : <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 -ProviderNamespace Microsoft.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 -ProviderNamespace Microsoft.ClassicInfrastructureMigrate ProviderNamespace : Microsoft.ClassicInfrastructureMigrate RegistrationState : Registered ResourceTypes : {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 -Environment AzureChinaCloud Id Type Subscriptions Tenants -- ---- ------------- ------- XXX@mcpod.partner.onmschina.cn User xxxxxxxx-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>"注意
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：
#您可以根据虚拟机所在的区域选择 China North 或者 China East PS C:\windows\system32> Get-AzureRmVMUsage -Location "China East" Name Current Value Limit Unit ---- ------------- ----- ---- Availability Sets 2 2000 Count Total Regional Cores 39 100 Count Virtual Machines 17 10000 Count Virtual Machine Scale Sets 1 2000 Count Standard Dv2 Family Cores 4 100 Count Standard FS Family Cores 16 100 Count Standard A0-A7 Family Cores 11 100 Count Standard D Family Cores 1 100 Count Standard Av2 Family Cores 2 100 Count Standard DSv2 Family Cores 4 100 Count Standard DS Family Cores 1 100 Count Basic A Family Cores 0 100 Count Standard A8-A11 Family Cores 0 100 Count Standard G Family Cores 0 100 Count Standard GS Family Cores 0 100 Count Standard F Family Cores 0 100 Count Standard NV Family Cores 0 0 Count Standard NC Family Cores 0 0 Count Standard H Family Cores 0 0 Count Standard LS Family Cores 0 100 Count Standard Dv2 Promo Family Cores 0 100 Count Standard DSv2 Promo Family Cores 0 100 Count Standard MS Family Cores 0 0 Count Standard Dv3 Family Cores 0 100 Count Standard DSv3 Family Cores 0 100 Count Standard Ev3 Family Cores 0 100 Count Standard ESv3 Family Cores 0 100 Count Standard Storage Managed Disks 0 10000 Count Premium Storage Managed Disks 0 10000 Count将同一个云服务下的虚拟机从 ASM 迁移到 ARM 上:
