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 anyone has done this please let me know.
Yes, you can do all of the controller upgrades and then move the AP's back. The incremental upgrades are more for formatting issues on the controllers.
