[PVE-User] about 2.3 to 3.0 upgrade

backup /var/lib/pve-cluster,  /etc/pve is mounted from it (this is an sqlite database).

mixing 2.3 and 3.0 should work, nothing too much different in cluster protocol, and live migration works from 2.3 to 3.0.

(But this to migrate all nodes to 3.0 as soon as possible)

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 unsupported.

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 ....
