Is it possible to delete a cluster which each node is not connected?

[m1n10n]

I have 6 boxes in a cluster that are all running proxmox. Since initial configuration, I have reconfigured the physical network connection and subnetted each node in the cluster, so that theyre all together in the same subnet, separate from my main network. Here is my problem; since i changed the physical wiring configuration, and each node now has a new local IP address, there is no connectivity between them in the previously configured cluster (since they are looking to resolve original IPs that no longer exist). I have no physical access to each node (they are offsite), but i am able to connect to to each of them independently via SSH and webgui.

Is there any way to delete the cluster configuration, or change the existing configuration to point to the new subnet IP addresses, without first connecting the cluster all together, and deleting it (since reconnecting the cluster would require me to physically change the configuration of the cat cables, and i dont have them next to me for a few months)

Any help is appreciated!

Hello,

I would recommend to re-build each node if you have a valid backup. Since the separate, a node without reinstalling is not recommended. However, you can find the steps and information below link [0] about to separate a node without reinstalling.
