First: there isn’t a quick and easy tool to migrate a Hyper-V machine to a vSphere ESXi machine… but luckily it’s doable if following the rules. Reserve enough time for the conversion and upload process. We will call the source and destination virtual machine w12a in this example. The VmWare datastore is called ds1.
- Make sure you have enough free space to store a fixed size hard disk copy of the source vm. USB storage will work too.
- Shut down the source Hyper-V VM. When this guest runs MS Exchange make sure to first stop and disable all MS Exchange services.
- Convert the VHD file with StarWind V2V Convertor to a “VmWare ESX Server image”. Do not choose “VmWare growable image” because you can’t edit the size of a vm workstation virtual hard disk on ESXi! The time this will take depends… in my case a 200 GB file took 31 minutes (6.45 GB/min). A 5.12 GB growable VHD took 16 minutes. This is because it’s configured at 100 GB size (makes 6.25 GB/min)… So take into account the configured total size. The convertor will create fixed size hard disks. This also means you can speed up the process by temporary making your VHD hard disks smaller if possible.
