I’m thinking about making some changes to my home server to make it a little more robust and let me do some cool new things with it (like actually trust it for backing up data to with NextCloud, replicating VMs or data across sites, etc). I’m just looking for any advice people might have for this process to migrate hypervisors.
What I currently have:
Windows 10 Pro OS with Hyper-V
Running some applications on the host OS (Plex/PRTG/Sonarr/Radarr)
Running a few VMs for things I set up after I realized “I should be doing these in VMs…”
4 HDDs for data, each just mounted individually. 2 for TV, 1 for Movies, 1 for Backups
What I’d like to have:
Better OS for running the hypervisor (Proxmox is what I’m reading may be best, but I’m open to suggestions)
Nothing running on the host OS other than a hypervisor
All my services running virtualized, be that via Docker in a LXC or a guest OS.
My Drives all in a RAID 5. Planning to add more drives at some point as well.
My thoughts on the process are that the “easiest” way may be:
Just throw a new OS drive in to install Proxmox on
Export my VMs from Hyper-V and import them into Proxmox
Set up the services I had running on the host OS previously in their own VMs/containers
Make a new RAID either: a. with new disks or b. by combining data from my existing disks so I can get a free few disks to start the RAID with, then moving data into the RAID and clearing out more disks to then add to the RAID, rinse and repeat until done (that’s a lot of data moving I’d like to avoid…)
I wasn’t sure if it would be a smarter idea to do something more like this though (assuming this is all possible, I’m not even sure that it all is). If this is possible, it might reduce my downtime and make it so I can tackle this in bits at a time instead of having an outage the entire time and feeling like I need to rush to get it all done:
New OS drive for Proxmox
Use Proxmox to boot my Windows 10 drive (this I’m not sure about) so that everything continues as it’s currently set up.
Slowly migrate my services out of the Windows 10-hosted VMs and host-installed services
I probably still have to deal with the RAID the way I mentioned above
Is there any other method I’m just totally not thinking of? Any tips/tricks for migrating those Hyper-V VMs? That part seems straightforward enough, but looking for any gotchas.
The reason I haven’t done anything yet is because I only have so much time in the day, and I’m not trying to dedicate an entire weekend to this migration all at once. If I could split up the tasks it’d make it easier to do, obviously there are some parts that would be time-consuming.
Proxmox is enterprise-oriented, so I’m not surprised. Personally I’ve just used the regular network to transfer files in and out of the VM. I suppose you could use NFS on the host, but I don’t know any use case for that off the top of my head. The hypervisor should just be a hypervisor.

Yeah sorry that was my phrasing, I meant VM - VM shared files or VM - Host, a la virtiofs or samba share (latter is supported but has meh performance)

Shit eh, my googling skills must be falling
Nah all of this was pretty recent I didn’t even know about it until I searched for it haha.
