Converting a large Hyper V VM to Proxmox

[Zilla]

I've converted Hyper V VMs to Proxmox before, but relatively small ones (32 GB).

My next challenge is to convert a 300 GB+ VM to Proxmox. The challenge is how to actually get this data over to the Proxmox host.

With the smaller VMs, I just copied the VHDX(s) to a portable SSD drive, dump in temporarily onto the host OS's storage, and convert from there.

But how have you all done larger VMs? Can I run the import directly from the USB drive, ie: not copy locally first? Or does that sound like a bad idea?

You can, it may be slower, it may fail if the USB disk is not great. But if everything aligns it will work. In the end, its just another disk.
Just do it.

If you have enough storage on your local datastore, I would just use SSH and directly transfer the large file from Hyper-V to Proxmox VE.

If you use sshfs to mount the old system's storage on the new PVE you save the need to supply additional (double-) space.

You see... there's more than one way to skin a cat
