As you may know, proxmox is my current choice for a hypervisor. Proxmox 7 is here and comes with a host of new features! In this video we’re cover all of the new features in Proxmox 7 as well as how to upgrade your Proxmox server safely. We’ll also cover all of the “scary” prompts you get while upgrading as well as some of the ways to make sure your upgrade is successful. So, if you’re thinking about upgrading your HomeLab to Proxmox 7, be sure to check this video out first.

If you’re looking to upgrade to Proxmox 8, see this post

Commands

Check your upgrade status

1

pve6to7 --full

First, make sure we have the latest packages

1
2

apt update
apt dist-upgrade

Update all Debian repositories to Bullseye

1

sed -i 's/buster\/updates/bullseye-security/g;s/buster/bullseye/g' /etc/apt/sources.list

We’ll also need to make sure we comment out any Proxmox ve 6.0 repositories.

1
2

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

Add Proxmox VE & package Repo

1

echo "deb https://enterprise.proxmox.com/debian/pve bullseye pve-enterprise" > /etc/apt/sources.list.d/pve-enterprise.list

If you’re using the non-subscription repository (like me) also run

1

sed -i -e 's/buster/bullseye/g' /etc/apt/sources.list.d/pve-install-repo.list

If you’re running Ceph, you’ll need to run

1

echo "deb http://download.proxmox.com/debian/ceph-octopus bullseye main" > /etc/apt/sources.list.d/ceph.list

Do the upgrade

2

apt update
apt dist-upgrade

network changes

If you’re running LACP / LAGG I found that you need to make some additional changes to your network config.See the comments in the config
