Cisco LAN Controller Upgrade

Have a 4400 WLC with software version 3.2.195.10

How do I upgrade and do I have to upgrade to each version until I get to the latest version whatever that is.

I'm trying to enable both global multicast mode and IGMP snooping on the current controller but can't find it, so I wondered if a firmware upgrade would add these elements in.

Wow, a WLC with v3 code!!

You'll need to do several upgrades to get to the latest version - v7.0.250.0, and you will lose most of your config as there are vast differences between v3 and v7.  Also, v7 code uses CAPWAP, not LWAPP, so if you have any firewalls allowing traffic on ports 12222 and 12223 you'll need to change that to 5246 and 5247.

The upgrade path is as follows:

Upgrade to 4.0.206.0 or later 4.0 release
Upgrade to 4.2.176.0
Upgrade to 7.0.250.0

There are some things you need to be aware of, or you may find yourself in a bit of trouble while doing the upgrade.  This link takes you to the 7.0.250.0 release notes (http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn70mr5.html#pgfId-784198) - the advice here MUST be followed.

Also make note that some of the APs which work with v3 code don't work in v7.  You'll find all the info you need in the link above.

Hmmmmm, sounds like it could be more trouble than it's worth.  Thanks for the great info though.

My pleasure!

If you can tell me what you've got at the moment, AP-wise, how your controller is currently configured, and what you want to achieve with it after the upgrade I can give you some help with that, if you're still interested in doing it.

Many thanks.
Basically believe it or not, all it is for is to allow the reflector airplay app to mirror from an ipad to a smartboard screen. From what I gather from colleagues is that the app will not work on the type of networks we employ unless global multicast mode and IGMP snooping are botyh enabled on the LAN controller. I'm aware you may not have come across this, but many thanks for the help you provided.
