9129 EWC software rollback.

rfalvarado — Tue, 15 Nov 2022 16:06:15 GMT

We have deployed a wifi network with a 9120 EWC and several APs.

At first the equipment came with version 17.3.5b and we upgraded to 17.6.4, leaving 17.3.5b as a backup image.

Now we want to go back to version 17.3.5b. Is there any way to go back to that version from the GUI or CLI or is it necessary to perform the upgrade process again?

1. ap image swap

2. ap image swap

Try applying the above commands

I'm not sure that will work @Arshad Safrulla because I think that only swaps the AP image not the controller image?

The install command doesn't work very well on EWC from my experience.

Also @rfalvarado if you are going to downgrade (maybe you want to support 1700/2700/3700 APs?) you should consider 17.3.6 which is out now. Personally I think 17.6.4 is a better quality release.

Is there a reason you want to go back that far? When you revert to an image that is on flash, it is like you are upgrading/downgrading. You will need to go through all the steps to push the image to all ap's, swap, reboot, etc.

It was just to make a faster roll-back without the need to upload the software.
