So I am trying to migrate from VMWare to Hyper-V and I'm using the MS tool Virtual Machine Converter 3.1.

However, the VM conversions are going super slow. Like 2MB a second which means that a 300GB machine would take 34 hours to convert. Any idea why this is so slow? Is there a quicker method I could use?

I looked at the VMDK's and there is about 3 or 4 per VM based off of partitions so I'm unsure how to use the powershell command which I think is simpler

This is the powershell command but there are multiple VDMK's per VM.

ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath d:\scratch\vmx\VM-disk1.vmdk -VhdType DynamicHardDisk -VhdFormat vhdx -destination c:\vm-disk1

Thoughts?

  • QoS of the NIC on ? on a 1G conenction it use 100mbps max in a transfert like that if QoS is on. – yagmoth555 May 17 '16 at 16:06

    You could try Disk2VHD or Starwind V2V Converter. - https://technet.microsoft.com/en-us/sysinternals/ee656415.aspx?f=255&MSPPError=-2147217396 - https://www.starwindsoftware.com/converter – joeqwerty May 17 '16 at 16:38
  • I haven't found Microsoft documentation on this yet, but I'm pretty sure the potential bottlenecks are network connection between the ESX and Hyper-V servers in question (as yagmoth555 suggests), converting machine computing power, and temporary conversion storage performance. Also it is not a fast process in general. We have a pretty robust setup and it takes about an hour per 100 GB for us. Obviously yours could be faster, but it's unlikely to be just a few minutes. – Todd Wilcox May 17 '16 at 16:58
  • @yagmoth555 I'll have to take a look at the QoS – tjcinnamon May 17 '16 at 18:08
  • @joeqwerty I looked into starwind, I'll give that a go. However, I'm a little confused becasue there's multiple VDMK's per machine. I'm curious do I just use the VDMX? – tjcinnamon May 17 '16 at 18:13
  • I'll be honest, I've not found this to be the best tool, I've had much better success with some of the paid tools. – Martyn C May 17 '16 at 20:59
  • @MartynC which tools? – tjcinnamon May 17 '16 at 21:17

    Sorry @tjcinnamon thought I had added them. I have great success with DoubleTake for both on-premises and cloud migrations and actually using Azure ASR for cloud migrations – Martyn C May 17 '16 at 21:18
  • Hi All, I'll give this a try this weekend and give you a response. – tjcinnamon May 19 '16 at 14:16
