how to replace proxmox 6 node with new hardware

[Dale.Sykora]

I currently have a five node cluster and want to replace node p2(172.25.36.12) with newer hardware (hp dl360g9 rather than hp dl360g8). The cluster has shared external storage (no local ceph, etc). I have migrated all guests off of node p2.

Do I need to unjoin old node p2 from cluster, poweroff, then build new node p2 with same IP and rejoin cluster? If not, what are the steps needed?

I think I found the answer here

if you keep same hostname, no need to unjoin/rejoin.


copy/restore

/etc/network/interfaces
/etc/corosync/corosync.conf
/etc/hostname
/etc/hosts
/var/lib/pve-cluster/config.db

then reboot, it should be ok.

Thank you Spirit! I already removed node when I saw your post. But I was able to add the new server with same name and IP and just join cluster again without any issues.
