Hi

Not a cause for concern. This is a simple process but i recommended to you use this procedure to upgrade WLC:

1- before copy firmware file to WLC provide backup of your configuration

2- after copy firmware file to the wlc, pre-download firmware to Access Points,

3- after the all APs download the firmware, restart your wlc

 - Check Release Notes for the intended version and follow installation procedures accordingly

If have any issue , I wanna roll back firmware  ,  Will I active the second firmware then all APs will follow right ?

-  Yes,

Besides the already named options, if possible have the APs attacked to PoE switches. So if one gets stranded and doesn't get back online after 30 minutes, simply shutdown the switchport for some seconds to force a reboot of the AP.

Don't forget to save your configuration before the reload

You should also clear the web browser cache after the upgrade, otherwise some pages might be broken. 

I am a bit confused about the versions though, I assume you meant to write 8.8.x to 8.10.x?

1. What is the model of the WLC? 
2. What exact firmware is the WLC running on and what exact firmware is the upgrade version? 
3. Post the complete output to the WLC command "sh sysinfo". 
4. What are the OLDEST model of AP and what are the NEWEST AP?

what model are those controllers?

[Scott Fella]

Your code you posted is wrong.  So that is a bit confusing.  Many have shared what they would do, but you also need to be comfortable doing this.  You didn't mention how many controllers and what controllers you have because there might be another way you should do this upgrade.  Also with flexconnect, you need to take into account the wan link bandwidth if your controller(s) are located in a different location.  It's easy for us whom have been doing wireless to say its easy, because we know how to get around things and do a few pre-test items before actually doing the upgrade. 

Please answer the questions Leo provided so we can better help you.

I already upgrade to 8.10 , New gui feature look better , everything going as well , too much happy ,

Butt cisco official bug this firmware ap1815-w the external port shown mac flapping.

There will always be some issue that affects certain ap models, controller models and features. It’s why testing is a major part of moving forward also understanding what bugs are more cosmetic than bugs that can affect user experience.
