Best FW upgrade path from 3.9.54 to 4.0.21?

I have 1 site with a US8-60w, 2 AC-IW and 1 AC-Pro all running 3.9.54.  Every time I click the firmware upgrade button, they go through the downloading / upgrade process, but then  the AP's stay offline (fortunately the switch just came back up with the old FW).  After 5 minutes I reset the POE ports going to the APs. (It also has a USG-3 on 4.4.29 that won't upgrade).

 

Is there a better way to upgrade or an intermediate firmware version I should go to?  I'm on unfi SDN 5.9.29.

 

Given the USG issues, I'm wondering if there could be something site specifc (ISP wise)?

 

@AmazedMender16  - sorry to tag you, but I've seen your controller upgrade path and wondered if you had something similar for FW>  :-)

Controller: 5.9.26 | Sites: 12 | Devices: 55 | Clients: ~250
USGs (4.4.28): XG8 (x1) | Pro4 (x4) | USG3 (x4)
UAPs (3.9.50): AC-Pro (x17) | AC-LR (x3) | Mesh-Pro (x2) | Mesh (x1) | Outdoor+ (x2)
USWs (3.9.50): US-16XG (x2) | US-40-500w (x3) | US-24-250w (x2)| US-8-150w (x3) | US-8-60w (x3) | US-8 (x2)

Hello @depasseg,

 

Hmm.. are you seeing any errors when upgrading?

Are the devices able to resolve dl.ubnt.com?

 

You can upgrade from 3.9.54 to 4.0.21.

Have you tried caching the firmware on the controller and upgrading once the firmware has been cached?

Settings > Maintenance > Firmware

Re: Best FW upgrade path from 3.9.54 to 4.0.21?

Thanks, but I think I figured out the problem - really slow bandwidth at that site (I think it might be a seasonal suspend, but it could also be a cable modem issue at that site). But the fact that you confirmed the upgrade path helped me start looking in other directions.

Caching worked, but the controller is in the cloud so that didn't do much to help. :-)

I'm downloading the USG FW via curl (remote consoled in) and the 104M download looks like it will take 3 hours.

No kidding right! It's less than dialup I think.

But they all eventually upgraded, so it's all good. (and no one is there for another month, so I've got time to figure out the speed thing now).
