The Merge-VHD cmdlet merges virtual hard disks in a differencing virtual hard disk chain.
The merge is from a specified source child disk to a specified destination child disk.
Merge is an offline operation; the virtual hard disk chain must not be attached when merge is initiated.
This example merges the virtual hard disk from VDisk4 to VDisk2. It merges all data from VDisk4 and
VDisk3, up to VDisk2. In this virtual hard disk chain VDisk4 is a child of VDisk3, which is a child
of VDisk2, which is a child of VDisk1. Finally, VDisk1 is a child of the Parent virtual hard disk.
In this example, all referenced virtual hard disks reside within C:\test. The VDisk4.avhdx and
VDisk3.avhdx are not deleted, however, they are no longer valid virtual hard disk files after the
operation completes.
