Just wondering if any functionality was added to 9 that will allow us to finally change an IP without having to jump through a bunch of hoops like migrating, disjoining and reinstalling. I need to vlan my home network and hoping for a better answer.

Thanks,
 
As changing the ip of a server is a rather uncommon usecase, there is no specific procedure implemented. On single server it is simple, in a cluster it is more complicated but possible too. Nevertheless I do not see a reason out of the box for the mentioned steps (disjoining, reinstalling) just for changing an IP, even in a cluster.

Unfortunately it isn't that uncommon. It's something that happens at every company from time to time as things change, network teams learn, or companies grow.

There really should be a documented and preferably scripted way to do this. Would be really nice if you could do it in the GUI.

The most recent thread I found on this forums for someone changing their IP was from Feb of this year. https://forum.proxmox.com/threads/changing-the-ip-address-of-one-node-in-a-cluster.161706/ and the first comment was "never change the IP, always remove/reinstall/rejoin" You saying that there isn't a documented process for that more or less reinforces that mentality. Heck, removing a node doesn't even clean up that node. You can't add the node back with the same name without it causing more issues. It's just a bad place to be.

These are the kinds of things I think proxmox needs to fix to go from homelab to enterprise. Much like the upgrade process from 8 to 9. Right now its a terrible manual process that people can mess up. It would be so much better if the proxmox team just made a script for upgrades. I love proxmox, but there are definitely things they need to improve to be taken seriously in an enterprise.
