kindly guide

direct upgrade from proxmox 8.4 to 9.2 is posisble or what kind of precaution should i take before going for upgrade ?

can it be possible to upgrade 9.1 or less version (version 9.1.x) with proxmox kernel 6.x ? not the new 7.x ?

Proxmox 8.4 to the current 9.2.2 is the way to go, 9.1 is possible but quite complicated.

Keep in mind that 7.0 is actually just 6.20 but Linus doesn't like large numbers. So the step is less daunting than it seems.

That said, you can always manually install a 6.x kernel and boot from that if you prefer.

in a production cluster (3 node) it is very difficult to do unknown experiment, and have short windows to do the upgrade, with ceph installed what is the best possible sugestion that is possible ? kindly advise

i have a very bad experience during upgrade from 7.x to 8.x, and the cluster gone down by few days, coz of that experience i am a little bit scared for the upgrade ............

I am also in need of an 8.4 to 9.2 upgrade guide. Did you ever figure this out?

I usually full reinstall node by node. Move the VMs, remove the node from cluster, reinstall, add back the node to cluster, move VMs back.

If you enable ZFS replication days in advance the migration is almost instant from one node to another.

I found this after I asked... https://pve.proxmox.com/wiki/Upgrade_from_8_to_9. your method sounds much safer, but much less convenient.

The upgrade guide OP posted is fine. The only issue we found was for https://pve.proxmox.com/wiki/Upgrad...Audit_Messages_are_Enabled_During_the_Upgrade, the guide says "excessive logging" which means any on screen prompts scroll off screen after only a few seconds. So I'd strongly suggest disabling that as mentioned.

If you have not yet pinned your NIC names you may wish to do that before upgrading kernels.
