WLC upgrade due to Advisory

[lcaruso]

Hi,

We have a 5508 WLC running 7.2.110.0 and need to upgrade according to the advisory released today.

It seems we have three upgrade choices:

7.2.110.0 to 7.2.111.3

7.2.110.0 to 7.3.110.0

7.2.110.0 to 7.4.x

I've not upgraded one of these 5508's before, but if they are anything like ASAs then I need to be careful.

Can anyone advise if upgrading from our current version to 7.4 requires planning. Same for 7.3.

How will the WLC upgrades affect the APs (3502i) ?

How does one recover from a failed upgrade on these WLCs?

Thanks.

The bug says it's fixed in 7.4(100.1).

I'm suspecting 7.4.100.1 is an engineering fix.  You'll need to raise a Cisco TAC Case and they will publish this for you.

Hi Leo,

You are correct, when we open a TAC case for this they publised a 7.4.100.6 code for us to fix the bugs we facing. These are not availabe to public to download.
