I have added a controller to my network which I intend to use as a development/testing controller. I need to upgrade its Firmware to Version 12.3.1 which is where the rest of my system is at. I'm having trouble finding the files (I believe .idf extension) that I will need in order to so.
Is there a place where I can download them? I inherited this system with the original disks which are for version 7. And the disks that were used for the upgrades seem to be missing.
You can download the iso's for the correct version from Guardian support.
