Change Proxmox Cluster IP

[Oer2001]

Hello,

we have a Proxmox Cluster with 4 nodes.
When we installed the nodes we did not know, that it is not possible to specify the migration network interface.
So at the moment all "migration traffic" uses the private network.

Setup:
proxmox0 (192.168.0.50), proxmox1 (192.168.0.51), ....
eth0 eth1 - bond0 - vmbr0: 192.168.0.x (private network)
eth2 eth3 - bond1 - vmbr1: 192.168.100.x (free)
eth5 eth6 - bond2: 192.168.110.x (ceph)

Is it possible to change the proxmoxX ip from 192.168.0.x to 192.168.100.x?
I saw an example where you have to change the ip in /etc/hosts and than restart the hosts.
Is this a solution or are extra steps necessary?

Thank you for helping.

Regards,
Oer

This is a solution, but an extra step is necessary: after restart and nodes occur active in the dashboard make at all nodes:

pvecm updatecerts

After I did this everything (Migration, HA, etc.) worked fine - but I cannot exclude that something else is recommended too ....

Kind regards
