Looking to migrate from virtual box within debian 12, to proxmox. Do I just import full backup?

[fickle crown]

I currently have HAOS in a virtual box vm within debian 12 bare metal. I am looking to wipe my whole drive, and install proxmox instead, where i will install the proxmox HA vm.
When I set that up, do I just import my latest full backup of HA on the startup page of HAOS? Will everything be restored as it was or will I need to reconfigure some things? Will all of my entities still work and things like cloudflared (installed as addon)?
Is there anything else I should be aware of and consider?

Also how do I pass my Zigbee dongle using ZHA through proxmox into HAOS?

Thanks

I'd recommend you download a backup and import it rather than the whole VM.
PVE has a USB option in the Hardware tab of the VM.

I think one of us has misunderstood. I currently have a virtualbox vm of HAOS (.vdi). Im looking to wipe the whole drive and install proxmox, then set up HAOS within proxmox using the proxmox .qcow2 file. I was saying is it as easy as uploading one of my backups from my current install into the new one and everything will be working?

also thanks regarding the USB option

You have to create the VM and import the image first but yeah, it's just importing the HAOS backup from the old system. Mostly everything will work. You might have to reconfigure networking and some paths if you used things like /dev/ttyX.
Don't forget to reboot the VM after restoring.

awesome thanks! And ok I would have forgotten that lol

I just need to minimise downtime as much as possible for HA and I am very new to proxmox. Just been following through a course on it first to prepare

also thanks for the very quick reply! Really appreciate it

This is an okay start: https://www.derekseaman.com/2023/10/home-assistant-proxmox-ve-8-0-quick-start-guide-2.html

brilliant thanks!

There's a lot of other things to be aware of. This guy lists some things:: https://youtu.be/VAJWUZ3sTSI
One of the most important ones is to enable the guest agent and Discard for the disk.
I don't have to mention to make backups and snapshots.
For backups I recommend PBS and snapshots this: https://github.com/Corsinvest/cv4pve-autosnap

oh ok thanks I will watch that shortly. Im not sure what the guest agent is in this context. I believe discard for the disk is basically ssd trim right?

It's similar: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_trim_discard
Guest agent makes sure that backups are consistent and other things: https://pve.proxmox.com/wiki/Qemu-guest-agent
