Upgrade cluster from 7.3-4 to 8.X with Ceph storage Configuration

[chtourouy]

Hello

I am running 7.3.-4 in cluster with 3 nodes and i plan to do a upgrade to 8.X.

i know this full guide : https://pve.proxmox.com/wiki/Upgrade_from_7_to_8#Actions_step-by-step but , i can't find a response for all my questions :

should i first ; removing a server from a Ceph cluster , start the update / upgrade and after reboot , i re add the server to ceph cluster ?

and it is possible to run proxmox cluster with different proxmox node & ceph version ?

thanks

EDIT : i use no entreprise subscription

1) on pve7, check that your ceph is 17.2 quincy. (upgrade ceph if needed)

2 ) upgrade all your your proxmox nodes to 8. (keeping the same version than ceph).

3 ) upgrade ceph to 18.2 or 19.X if you want
