Upgrade Proxmox VE from 2.3 to 4.4

[gcwgc]

I just walked into a new environment that's currently running Proxmox Virtual Environment
Version: 2.3-13/7946f1f1 on 3 servers and I would like to update to the latest. I'm seeking advice on what's the best way to do so? Can I do a direct update to 4.4, or would I have to do from 2.3 to 3.0, 3.0 to 4.0, 4.0 to 4.4? If I have to do 2.3 to 3.0, 3.0 to 4.0, 4.0 to 4.4, how do I do so? Do I have to update each server independently, or running the update(s) once pushes them out to all three? Keep on mind I'm completely new to Proxmox hypervisor & Linux. I have used other hypervisors like Hyper-V & Vmware ESXI. Proxmox seems like a whole new and different beast.

Hi,

yes you have to go this way there is no direct path to 4.4

Here are the howtos
https://pve.proxmox.com/wiki/Upgrade_from_2.3_to_3.0
https://pve.proxmox.com/wiki/Upgrade_from_3.x_to_4.0

I would make it node by node to the next level.
What I mean is nodeA to 3.0 then nodeB to 3.0 ...
After all nodes are on 3.0 update to PVE 4 the same way.

If you have a shared storage I would consider if you would make a clean installation.
Normally this is faster then upgrade path.
