Hello all,
We have a running 4.4 Proxmox 3 Nodes Cluster (vmbr0 has public IP) with ceph(separate internal nic) and about 10 VM and 30 CT. As we got a new A.S Number, we would like to be able to change the public IP addresses on all 3 nodes in the cluster (not hostnames). Given our setup, is it possible to do so? If yes, what would be the correct procedure?

The actual setup:
Node1: 1.1.1.1
Node2: 1.1.1.2
Node3: 1.1.1.3

Future setup:
Node1: 2.2.2.1
Node2: 2.2.2.2
Node3: 2.2.2.3

Thank you all in advance
