How it works...

VUM allows for virtual machine hardware, tools, and virtual appliance upgrade by creating the relevant baselines. In the previous recipe, a VM that was imported from a vSphere 5.x hardware had an older virtual hardware. The predefined baseline validates the virtual hardware of the virtual machine against the latest available on the host it's currently registered on. In the previous case, the virtual hardware associated with vSphere 6.x, virtual hardware version 13 was available. On remediating the VM, we see that the virtual hardware was upgraded to vHW 13. The workflow also allows for snapshots of the VM to be taken as a rollback measure. In addition, the task can be scheduled depending on business requirements.
