.SYNOPSIS Copy a VM. It is possible to move vms across regions, subscriptions and vnets using this command .DESCRIPTION Copy a VM. It is possible to move vms across regions, subscriptions and vnets using this command VM must be stopped before running this script and any static ip on the source vm must be removed i.e. it must be set to a dynamic ip .PARAM SourceSubscription The source subscription .PARAM SourceServiceName The source cloud service .PARAM SourceVMName The source vm name .PARAM DestSubscription The destination subscription .PARAM DestServiceName The destination cloud service .PARAM DestVMName The destination vm name .PARAM DestLocation The dedstination Azure region .PARAM DestStorageAccount Destintaion storage account. Copys of the vm disks will be made in this account .PARAM DestContainer Destination container - created if not already present .PARAM DestVnetName The destination vnet. If blank the dest vm will not be placed in a vnet .PARAM DestSubnetName The destination subnet, must be specified if destvnet is specified .PARAM PerformVhdBlobCopy You can use $PerformVhdBlobCopy to control if the vhd copy is performed - e.g. if you previously copied the vhds successfully but the vm creation failed for another reason .PARAM OverwriteDestDisks You can use $OverwriteDestDisks to control whether you create the dest disks - e.g. if you previously suceedded in creating the dest disks but the vm creation failed for another reason .EXAMPLE # Copy vm to a new vnet in a different region and subscription Copy-AzureVM -SourceSubscription 'sourceSubscription' ` -SourceServiceName 'sourceServiceName' ` -SourceVMName 'sourceVMNam' ` -DestSubscription 'destSubscription' ` -DestServiceName 'destServiceName' ` -DestVMName 'destVMName' ` -DestLocation 'North Europe' ` -DestStorageAccount 'NorthEuropeStorage' ` -DestContainer 'vhds' ` -DestVnetName 'NorthEuropeVNet' ` -DestSubnetName 'Subnet-1' ` -PerformVhdBlobCopy $true ` -OverwriteDestDisks $true #> function Copy-AzureVM { [CmdletBinding()] param ( [Parameter(Mandatory=$true)][string]$SourceSubscription, [Parameter(Mandatory=$true)][string]$SourceServiceName, [Parameter(Mandatory=$true)][string]$SourceVMName, [Parameter(Mandatory=$true)][string]$DestSubscription, [Parameter(Mandatory=$true)][string]$DestServiceName, [Parameter(Mandatory=$true)][string]$DestVMName, [Parameter(Mandatory=$true)][string]$DestLocation, [Parameter(Mandatory=$true)][string]$DestStorageAccount, [Parameter(Mandatory=$true)][string]$DestContainer, [string]$DestVnetName, [string]$DestSubnetName, [boolean]$PerformVhdBlobCopy = $true, [boolean]$OverwriteDestDisks = $true ) # This is a 3 stage operation # 1) copy the vhds to a new storage account # 2) create new disks from the copied vhds # 3) create the vm from these new disks # Pre conditions if(![string]::IsNullOrEmpty($DestVMName) -and [string]::IsNullOrEmpty($DestSubnetName)) { throw "You must set the dest subnet name if you set the dest vm name" } $sourceVM = Get-AzureVM -ServiceName $SourceServiceName -Name $SourceVMName $staticIP = Get-AzureStaticVNetIP -VM $sourceVM if($null -ne $staticIP) { throw "Can not copy a vm with a static ip.
