Switchting from Supervised VM to Home Assistant OS VM on Proxmox

Hey, seeing my Debian 9 Supervised install (in a VM on Proxmox) is now unsupported, and it could do with a reinstall, I think I have two options:

I was wondering what the state of VM support is, specifically on Proxmox. 3 months ago I wanted to make the switch to QCOW2 on Proxmox, but that was in Beta back then. It looks supported now. Anything which is helpful to know to make the switch?

I’m using git and Ansible op my laptop to version and deploy my yamls to the current setup and would like to keep working that way.
