2 Cisco WLC 5508 controllers and software upgrade 7.6.130 + FUS 1.9

[Kevin Lotko]

Hi

I have two WLC 5508 controllers that need 7.6.130 and FUS 1.9 installed. (Current version 7.3 and FUS 1.7)
 

Configuration: One controller is at Site A and the other controller is at Site B (two different states..)
 

They're configured so that if Site A goes down, Site A AP's will failover to Site B and vice versa ..

- What would be the recommended approach for upgrading the software to 7.6.130.0 (from 7.3) and also upgrading FUS 1.9 (from 1.7)?

My plan was to download 7.6.130.0 to both controllers and pre-download the software to all AP's (about 100 total between both sites) and then reboot the controllers at night at the same time? Or one before the other? 

Step 2. Install FUS 1.9 to each controller.

I'm concerned over what might happen during the upgrade and AP failover etc..

Thanks

This is what I would do:

Upload v7.6.130.0 to all WLCs and then use the pre image download to push the image to all access points. 

Dont reboot the wlc

Image swap in the access points so that v7.6.130.0 is primary

Move all access point to one of the WLCs (A)

Enable ap AAA authentication on the WLC that has no access points and the one you will work on first.  This prevents access points from joining  

Reboot the WLC (A)

Upload the FUS 1.9.0.0

Reboot WLC (A) this takes up to 45 minutes

When the WLC (A) comes back online, uncheck ap AAA authentication

Move access points from WLC (B) to WLC (A)

Enable ap  AAA authentication on  WLC (B)

Perform all the other task you did earlier on WLC (A)

That's it.

I like that idea and very well may use it however.. on a side note, could I just disable mobility groups (in GUI) by changing the IP of either WLC mobility group member so that AP's don't failover? Would this work? and then when i'm finished change the IP address in mobility groups back?

Where's the checkbox for enabling AAA? (getting back to your idea)

How do you manually move AP's to another controller? ie.. A to B like you mention

Thx

On the gui go to the Security tab then AP Policy. 

To move access points, you can do it if you have Prime Infrastructure or follow this link:
