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

适用场景

用户拥有多个云服务但是在同一个 VNET 下,希望将这些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

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

解决方案

  1. 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 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}
    
    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
    
    #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>"
    
  2. 检查 ARM 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"

    1. 将同一个 VNET 下的虚拟机从 ASM 迁移到 ARM 上

      #将 ASM 下 VNET 的名称赋值给变量方便后面调用
      PS C:\windows\system32> $vnetName="<VNET 名称>"
      
      #验证 VNET 是否符合迁移条件
      PS C:\windows\system32> Move-AzureVirtualNetwork -Validate -VirtualNetworkName $vnetName
