<![CDATA[Upgrading pfsense hardware – interface names changes cause problems]]>With pfSense 2.5 someday, we had a chance to update our pfSense 2.3.4 router to somehting more modern anway.  We were running on one of those nice little Celeron boxes with four Intel GB interfaces and 8GB of ram.  We acquired an i5 version (yes, I know it's far more power tha pfSense needs), with four interfaces BUT, these show up in FreeBSD as igb0-3 as oppsoed to enc0-3. 
If we try to restore a backup – as expected, many things break.  We did a little hand editting but in general, the web interface just will not start.

Is there a proper way to ugprade when the interface names change?

What exactly you have edited? In general you need only replace igb0, igb2, igb3 (exact match) with enc0, enc2, enc3 in config, but it does not mean you have the same physical layout on new hardware and there can be some port mess around it, so you need to check for real, physical port numbering and find out which port is which and put you cables according to this new layout.
