An Azure service that is used to provision Windows and Linux virtual machines.
In place upgrades are not supported as of now.
Microsoft does not support an upgrade of the operating system of a Microsoft Azure virtual machine. Instead, you should create a new Azure virtual machine that is running the supported version of the operating system that is required and then migrate the workload.
