Add NICs to an Azure VM

Q. How do I add additional NICs to an existing Azure VM?

A. You cannot add additional NICs to a VM, you have to configure multiple NICs at time of VM provisioning. If you need to add NICs to an existing VM the method would be:

1. Delete the VM while keeping its disks (you could optionally export its JSON before deleting as a basis for the creation of a new VM, e.g. http://windowsitpro.com/azure/create-json-file-existing-resource-group-azure)
2. Create a new VM using the existing disks with the required NIC configuration
