Sometimes you may need to convert a virtual disk file from one format to another. Converting virtual disks can be required when migrating a virtual machine from one hypervisor to another for testing purposes, or if you have selected an inadequate format of a virtual disk for your virtual machine (VM) during the VM’s creation. The most popular virtual disk formats are VHD, VHDX, and VMDK. You cannot import VHD to VMware products until you convert Hyper-V VHD to VMware VMDK. This blog post explains how to convert VHD to VMDK which may be useful when you want to convert Hyper-V VMs to VMware VMs.
