Answer 1

You can copy the managed Disk from East US to West US. The following powershell Script will do the task for you.

$sourceRG = <sourceResourceGroupHere>  
$sourceDiskName = <sourceDiskNameHere>  
$targetDiskName = <targetDiskNameHere>  
$targetRG = <targetResourceGroupHere>  
$targetLocate = <yourTargetLocationHere>  
#Expected value for OS is either "Windows" or "Linux"  
$targetOS = <yourOSTypeHere>  
  
$sourceDisk = Get-AzDisk -ResourceGroupName $sourceRG -DiskName $sourceDiskName  
  
# Adding the sizeInBytes with the 512 offset, and the -Upload flag  
$targetDiskconfig = New-AzDiskConfig -SkuName 'Standard_LRS' -osType $targetOS -UploadSizeInBytes $($sourceDisk.DiskSizeBytes+512) -Location $targetLocate -CreateOption 'Upload'  
  
$targetDisk = New-AzDisk -ResourceGroupName $targetRG -DiskName $targetDiskName -Disk $targetDiskconfig  
  
$sourceDiskSas = Grant-AzDiskAccess -ResourceGroupName $sourceRG -DiskName $sourceDiskName -DurationInSecond 86400 -Access 'Read'  
  
$targetDiskSas = Grant-AzDiskAccess -ResourceGroupName $targetRG -DiskName $targetDiskName -DurationInSecond 86400 -Access 'Write'  
  
azcopy copy $sourceDiskSas.AccessSAS $targetDiskSas.AccessSAS --blob-type PageBlob  
  
Revoke-AzDiskAccess -ResourceGroupName $sourceRG -DiskName $sourceDiskName  
  
Revoke-AzDiskAccess -ResourceGroupName $targetRG -DiskName $targetDiskName
