Suggestions for migrating from Windows Server to Proxmox (startrek.website)

I was wondering if I could get some suggestions from the community about the best way to go about migrating from Windows Server on my homelab host to Proxmox.

Background: Currently running Server 2022 Datacenter on my host because that's what I was familiar with. Using Hyper-V to manage multiple VMs like HomeAssistant and TrueNAS among other things. I have multiple container apps running within TrueNAS. There's an HBA passed through Hyper-V to the TrueNAS VM that has all of my HDDs connected to it. I'm just looking to migrate away from anything Microsoft/Windows.

Way Forward: The only procedure that I could come up with in my head was moving everything off of the NAS to my personal PC if I have the space, or maybe multiple PCs in the house. Back up all of my configs. Install Proxmox on the host, build out the VMs again, then restore the configs and just hope everything works the same. Or, just backup my configs build the new VMs on proxmox, restore and hope the new TrueNAS VM sees the data on the HDDs? I don't know if that would work.

If someone has a better idea, I'd like to hear it. Is there any way to dual boot Proxmox on the host maybe and slowly migrate things 1 by 1? Can you convert the VMs from Hyper-V before I install Proxmox?

Thanks everyone!

God, I'm sorry you had to use Hyper-V.

As challenging as Proxmox is for someone new to it, it's so much better than Hyper-V.

I have a 3-node Proxmox cluster with HA that is currently collecting dust because I overbuilt when rent was cheap and now I can’t afford to run it; so I’m running essential services on my desktop PC with Hyper-V and NONE OF THE NETWORKING MAKES ANY GODDAMN SENSE oh my god why can’t I get WSL2 and a VM to see the fucking LAN at the same time they don’t need to talk to each other I just need HomeAssistsnt and paperless to work from LAN devices why is this all so shit
