Disk Converter tools are essential especially when you are migrating virtual machine workloads between two hypervisors. Each Hypervisor uses different virtual machine disk formats such as VMDK for VMware virtual disk and VHD for Hyper-V based virtual machine disks. You may need some tools to convert VHD to VMDK if you are importing VM from Hyper-V to VMware ESXi because ESXi host will not understand the disk format of Hyper-V virtual machine (VHD). There are lot of free tools in the market to convert disk format of virtual machines to make it compatible to different hypervisors.

We are going to list out the some of 3 of the free tools to Convert VHD to VMDK and vice versa. I have personally used this tools for my lab environment to convert virtual machine disks such as VHD to VMDK and VMDK to VHD to import and test virtual machine workloads across Microsoft Hyper-V and VMware ESXi. The order listed here may not have any preference of 1 or 2 or any order. I have explained some of the important features of each of the free Conversion software for better understanding.
