I have 3 WLC running 220.127.116.11 code that I need to upgrade to a newer code to support the 802.11N aps that have been purchased. I have moved all of my aps off of one of my controllers so they will not be bouncing up and down while the upgrades are taking place. My question is this. I know I need to go to 18.104.22.168 and then to 22.214.171.124 and then to 126.96.36.199 and then to 5.2.xxx. Can I just upgrade the controllers from start to finish and then move my aps back over to the controller so they can upgrade just one time or do I need to increment them along with the WLC upgrades from release to release to release?
If I can do the aps in just one step that would save a lot of time. I would like to just upgrade them one time and the controllers as needed per the docs.
If that is a true statement that will save a lot of time. Someone on another forum suggested that I might have to increment the aps along with the wlc because of going from lwapp to capwap. Does that sound right?
I have no idea what WLC you have. But if you have a 4400 series, what I would always do is disconnect the uplink ports (this would cause your APs to join the next controller). Connect yourself to the service port and upgrade via this port. Once your done, re-enable the uplink ports and observe the APs come back.
NOTE: Personally, I'd stay away from 5.X unless you really need it. 188.8.131.52 or 6.X is preferred because 5.X is well-known to be "buggy". I understand that the 7.X will be out sometime this year. So if you can wait ...
