I'm currently required to upgrade a 2504 from 8.0.140.0 to 8.3.143.0 to support some 3802i's that are being added. I see the minimum required FUS is 1.9. The website says to upgrade the FUS first and then when the controller is back up to upgrade the firmware. I've also heard it's better to upgrade the controller to 8.3 first and then upgrade the FUS. Is either order fine? I'll be doing this in an extended maintenance window but I'll be remote so want to be prepared.
Ah ok. Hint, for your next order, make sure the AP order number is ….-K9 and not ….-K9C. The C stands for Controller, which means it has ME image installed and set as default. I think it's also a tiny bit more expensive.
