Mount an Ubuntu 8.04.3 LTS VM to server 2016 hyper-v

Hi, 

We have a Ubuntu 8.04.3 LTS VM runnung on VMware ESXI 6.5u2 at the moment. However, we would like to get rid of ESXI and move this VM to Window Server 2016. However, is any method to mount this old VM on hyper-v? Also, as VMware VM uses .vmdk file, is anything i need to be aware if i convert it to .vhdx file? 

Thanks

Thomas
