Migrate old pfSense appliance with em0 (E1000e) NICs to new appliance with VMXNET3 NIC's

Enso_

Hello,

As the title suggests, are there any gotchas when restoring the configuration of an outdated pfSense appliance into a new one if the network adapters have changed from E1000e (current) to VMXNET3 (new)?
My concern is that the old appliance is configured with E1000e NICs, whereas the new one will use VMXNET3 NICs.

My plan is to back up the configuration file from the current appliance, edit it to change the interface names from em0 to vmx0, leave all other settings unchanged, save the file, and then restore it to the new appliance.

Thanks!

@Enso_ In the simple case, no.

Yes you can edit the config file. Just be sure not to do a search and replace in case the NIC strings are used in an encoded string.

If you're not using complicated VLANs you should be able to just restore in the web GUI and it will ask you to assign the interfaces. Save, then apply to reboot. (note if it doesn't work it will stop on boot to ask at the console to reassign interfaces)
