Re: [PLUG] Endian firewall - was Swapping motherboards

Your approach (point the bridge devices at the new/higher eth device

eth0/1/2, you can either remove the persistent names via the
instructions I will link, or simply edit them to remove the defunct MAC
addresses and re-use eth0 for the new motherboard ethernet.

As soon as Eric said the "Ethernet ports are coming in on eth2, eth3, and eth4" the light-bulb went off for me, but you beat me to it. I can tell you how many times this has messed me up, usually when cloning RH VMs.

FWIW I suggest fixing the root cause so that 3 years from now you aren't scratching your head about where the heck eth0 went.
