Yeah I would open a ticket about that. It should recognise the 7100 and setup the switch and VLANs etc so you can connect out on the default interfaces.
If that's not happening then it isn't recognising the hardware for some reason. That might mean the data passed by the bios is incorrect.
Also important to note is that coming from a pfSense version that old probably means it has an old Coreboot version and that will need to be updated. That must be done in an older pfSense version, 23.05.1 or earlier.
