[PVE-User] about 2.3 to 3.0 upgrade

Yep, config folder is shared and AFAIK format of config files hasn't
changed. Well you can simply tar /etc/pve directory just in case.

Reinstall and reconnect probably will do, but there may be problems
with SSH keys since reinstalled node will get new one, i does not know
how proxmox handles this case.

I have both 2.3 and 3.0 nodes in my cluster. No problems detected,
everything works (including live migration), but still this is

Ho to all ...

And thanks in advance for any help ..

I have a running 5 node pve 2.3 cluster .

To upgrade to 3.0, the how-to advises to make a backup of all config
beforehand .

But, in a cluster, all config files are replicated in all nodes,
correct ?

So, if something goes wrong in upgrade, all I need to do is reinstall
that node from scratch and reconnect to the running cluster ...

Am I wright ???

And. if something indeed goes wrong, I can install PVE 3.0 and
reconnect to running 2.3 cluster, or I MUST reinstall 2.3 ?

Just looking for best practices ....
