How to increase size of unmanaged disk attached to classic VM

Question

Greetings. I have a classic VM (using the old Service Manager model) that I need to expand the storage on. The disk in question is a data disk, not an OS disk, and it is an unmanaged disk of type Premium (SSD). What are my options for exiting the size of this drive? Or, would it be easier to just add a new drive to this VM, assuming the VM has capacity for it? I've searched and received no meaningful hits other than this one.

@AzureSupport on Twitter also recommended the same article. However, this article doesn't mention how to do this with "classic" deployment model VMs. So, can anyone confirm the process for doing this with a classic VM? Is it the same, or is there a different process, or is it not possible?

Thanks in advance for any help.

Here you are! FYI vm needs to be stopped.
