Restore a backup after LAN Port failure

[frudda]

Hello

I wonder if this restore of  a backup is possible after ETH0 Port failure (dead):

1. Reinstall opnsense in the exact same version as before.
2. Boot up and restore an edited XML with the ETH0 name changed to ETH2 name

By this i mean to switch to a not faulty Lan port by editing the XML then restore it. If not, is there any other way to resolve my problem? I have 2 unused ports

Sounds plausible. What happens when you try? 

If you're worried about making irreversible changes, boot Clonezilla and image your boot drive through a working NIC or onto USB connecteded storage.

You'll likely have some wriggle room with versions.

It works, perfectly. I restored the modified backup from shell.
After the reboot everything was running normaly and lan/vlans was moved to a different port 👏 (I reinstalled the exakt same version of OPNsense the backup was taken from)
