The 2504, 5508 & WiSM2 are the only WLC's that will support 7.2.  If you have a mix, then maybe going to is your best bet.

excellent, thanks.  Im actually in the process of eliminating the 4400's.  I just need to join the 5500 to the mobility group and start moving the AP's over.  I guess once I do that I will upgrade the code on the 5500's.  Thanks!

Well then you can upgrade your 5508's directly to, but remember that there is a FUS code also that you will need to install.  The release notes will explain the process.

perfect, thanks for the info.  Do you think the best course of action to introduce two new 5508's into the environment is the following:

1. load the same code as the rest of the 4400

2. apply the same config (wlan, security, etc) as the 4400's

3. join the same mobility group as the 4400's

4. move over a handful of AP's to the new controllers and test

5. decommission the 4400's

your thoughts?  Anything I'm forgetting?

That sounds like a solid plan. The last step would be to upgrade to 7.2, but other than that looks good.

I was looking at copying over the config from the old controllers to the new but it looks like the configs are not like standard configs (like switches and routers).  Is that the best way or is there a better way to prep the new controllers to add them into the mobility group?  Right now I am going page by page in the gui and making the changes.

Personally I would put them all at the same version they are capable of going to. Then you can do a tftp config backup and copy that config via tftp to the new controllers.
