[PVE-User] Proxmox 6.3.3 upgrade [ Out of 4 node cluster, can I only upgrade one only to the next stable release ]

[Joseph John]

Dear All,

Good afternoon
I have a test environment of proxmox with 6.3.3 , I have clustered it. We
have 4 nodes clustered together.
Planning to upgrade it one by one
Like to know if I upgrade only one of the nodes in the beginning to check
it , will it affect the system
i.e. the 3 nodes will be onb 6.3.3 and the 4th node I am looking for
upgrading to the next stable release .
My query is that will the clustered system work after the first node
upgrade
Appreciate your advice
thanks
Joseph John
