Migrating a Hyper-V host from Windows Server 2019 Core to Windows Server 2025 requires attention beyond just the virtual machines. The host's configuration is equally essential and includes network cards, vSwitches, and default paths, all of which need to be transferred accurately. Using Windows PowerShell, you can export key settings and restore them on a new server.

Instead of walking through the entire wizard in Hyper-V Manager to create a virtual machine, you can speed up the process using Quick Create. By default, this tool uses virtual hard disks (VHDX) provided by Microsoft. Alternatively, you can set up a custom gallery and populate it with your own images.
