Upgrade/Resize Azure VM without affecting the network host ID

Question

I need to upgrade my Azure VM to a different size machine for reliability. We use this machine as a license server and those license files are locked to the machine network physical address or Host ID. Is it possible to retain the networking settings, specifically the physical address?

Hi Trent Rains,Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

This article discusses how Azure assigns MAC addresses to NICs and provides a workaround for retaining the MAC address by reusing the existing NIC when redeploying a VM. This approach ensures that the MAC address remains consistent, which is essential for license servers that bind licenses to the MAC address.
