Has anyone had experience migrating virtual machines from Xen to Hyper-V, both with Linux and with Windows as a guest OS?
How and what is the best way to do it?

Answer 1

The main thing here is just to convert the format of the virtual disk, nothing else is needed for the virtual machine. Well, it is also desirable to rewrite the main parameters of the virtual machine in advance: vCPU, vRAM, disk type (scsi, sata, sas, ide, etc.). And then everything is simple - you copy the virtual disk (s), google tools for converting (vmdk-vhd, for example), start a virtual machine with the same parameters on the new hypervisor, connect the converted disk to it, it should work, I did this many times, with different hypervisors back and forth. The main thing is to check to merge snapshots in the first place, before any operations!
How to automatically migrate all this goodness, if you have a hundred machines, I won’t tell you, there are proprietary solutions, perhaps.
There is also a very rough way, but it works like an ax: you put Paragon or Acronis on the virtual machine itself, "back up" it in the desired format, they both know how to backup the system into a vhd image, and connect this backup-vhd to the virtual machine in hyper- v.

Answer 2

Transferred back and forth via Acronis + UR
After booting with regular SATA (or integrated firewood via UR), then created a small disk so that firewood could be put into the guest OS

Answer 3

Personally, my opinion is Hyper-V is bad. There is no need to migrate.
And on the case - There is a wonderful utility from Russinovich disk2vhd.
On machines with Windows, we run it on a running machine and get a ready-made VHD / VHDX output.
Linux - Acronis or Clonezilla or dd as a last resort. And how to deploy on Hyper-V - there is no experience.
