Hi, i have the exatly same problem at the moment.
I'm switching from a homebuilt (not by me) machine with 2 interfaces (WAN and LAN) to a brand new XG-7100.
I tried to restore, but i can only choose between ix0, ix1, ix2, ix3 and ovpns1, none of these are my ETH ports.
Is it enough to replace the data in the interfaces section, in the backup file, with the data from the interfaces section from the new firewall?
Here are the sections from backup files:
