Full steps can be found at https://i12bretro.github.io/tutorials/0596.html

💡 NOTE: These steps are for a single standalone Proxmox server. They have not been tested in a clustered environment
 
🚨 WARNING: Make sure to create external backups of all important VMs and CTs just in case something goes wrong. You've been warned.
 
   01. Log into Proxmox VE, either at the console or the web UI and launch the web shell
   02. Stop all running VMs and CTs
   03. Run the following commands to make sure Proxmox VE is running the latest 7 updates
         # disable proxmox commmercial repo
         sed -i "s/^deb/\#deb/" /etc/apt/sources.list.d/pve-enterprise.list
         # add the proxmox community repo
         echo "deb http://download.proxmox.com/debian/pve $(grep "VERSION=" /etc/os-release | sed -n 's/.*(\(.*\)).*/\1/p') pve-no-subscription" ≫ /etc/apt/sources.list.d/pve-community.list
         # update software repositories
         apt update
         # install software updates
         apt dist-upgrade -y
         # clean apt cache
         apt clean
         # run the upgrade checklist utility, resolve any issues reported before continuing
         pve7to8 --full
         # update apt repositories to bullseye
         sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list && sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list.d/pve-community.list && sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list.d/pve-enterprise.list
         # update software repositories
         apt update
         # install software updates
         apt dist-upgrade -y
         # clean apt cache
         apt clean
         # reboot
         reboot now
   04. That's it, Proxmox VE has now been updated to the latest v8.x
