Azure VM: Adding a Reserved IP address to an existing VM

Question

What I have read so far on the web is that there is no way to add a reserved IP to an existing VM (unless I recreate the VM which I am trying to avoid). However, I have noticed

Answer 1

For new VMs (with resource manager) you should do the following:

Create new static IP address:

$ip = New-AzureRmPublicIpAddress -Name "<ip-name>"  -ResourceGroupName <group-name> -Location eastus -AllocationMethod Static

Get information about VM Network Interface:

Get-AzureRmVM -ResourceGroupName <group-name> -Name <vm-name> | Select -ExpandProperty NetworkProfile

Get corresponding network interface and set new ip and update NIC:

$netInt = Get-AzureRmNetworkInterface -ResourceGroupName "group-name" -Name <nic-name>
$netInt.IpConfigurations[0].PublicIpAddress = $ip
Set-AzureRmNetworkInterface -NetworkInterface $netInt

Answer 2

At this point, we don't support the capability to associate a Reserved IP to an already existing VM. We are currently working on the capability to reserve the IP of an existing VM.
