Update proxmox 6.4.x to 7.x

Updating a proxmox system from version 6.4.x to 7.x using https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0

Proxmox VE 6.x is based on Debian 10.x which is called “buster”.
Proxmox VE 7.x is based on Debian 11.x which is called “bullseye”.

  1. Make sure you have a backup of all VMs, Containers, Proxmox itself etc.
  2. Login via SSH/CLI
  3. Check your sources.list file, should look like this:

    cat /etc/apt/sources.list

    deb http://deb.debian.org/debian     bullseye main contrib
    deb http://deb.debian.org/debian     bullseye-updates main contrib
    # security updates
    deb http://security.debian.org     bullseye/updates main contrib

    You may use sed -i 's/buster\/updates/bullseye-security/g;s/buster/bullseye/g' /etc/apt/sources.list to update "buster" to "bullseye".

  4. Check the enterprise repository:

    cat /etc/apt/sources.list.d/pve-enterprise.list

    When running Proxmox VE 7.x with No-Subscription use:

    deb http://download.proxmox.com/debian/pve bullseye pve-no-subscription

    When running Proxmox VE 7.x with a subscription use:

    deb https://enterprise.proxmox.com/debian/pve     bullseye pve-enterprise

  5. Check Proxmox version using:

    pveversion -v

  6. Run the pve6to7 script

  8. Update your repository and packages:

    apt update

  9. Now upgrade the packages:

    apt dist-upgrade

  10. Reboot to activate the new Kernel, to check if you got all packages, run 'pveversion -v' and compare your output (all packages should have equal or higher version numbers): 
  11. Check Proxmox version using  

    pveversion -v
