Clone Hyper-V virtual machines When importing (cloning) Hyper-V virtual machines, make sure each virtual machine has a unique ID. Discovery identifies virtual machines with duplicate IDs as the same machine. Export the virtual machine from the Hyper-V server. Import the virtual machine into a different server, making one of the these choices: Move or restore the virtual machine: This selection clones the image, using the same ID, and moves it to another server. The original image remains on the Hyper-V server. Copy the virtual machine: This selection copies the virtual machine, using a different ID, and moves it from the Hyper-V server. This is the best selection and does not require any further action before you run Discovery. If you import the Hyper-V clone using the Move or restore selection, be sure to delete the original image from the Hyper-V server.When Discovery encounters two virtual machines with the same equivalent serial numbers, it creates only one configuration item (CI).
