Once you have your ideal update picked out, download it from Cisco’s website. For example, if you look at the 8.8 release notes it tell you that any version lower than 8.5 has to update to 8.5 first before you can update to 8.8. Had I skipped checking the release notes I would have had APs down after the update.Īnother thing you need to look out for in the release notes is upgrade paths. Because of this I opted to replace our outdated APs with AIR-AP3802I-B-K9 which are supported. I read the release notes and noticed that some of our older AIR-LAP1142N-A-K9 APs weren’t on the “Supported Cisco Access Point Platforms” list. In my case, I wanted to update to 8.8 but I saw that 8.5.135.0(ED) is the latest suggested release, so we’ll start there. I also recommend reading the release notes to verify the hardware you have in your environment is supported. I always recommend sticking with Cisco’s suggested releases, which are the ones with the gold star. The first thing you need to do is determine the software version you wish to update to. Less downtime mean less user’s that will notice anything is going on, which always the goal when it comes to keeping your network humming along! Verifying Compatibility and Downloading Update Files Updating Cisco WLCs is a fairly simple process but there are some different paths you can take to help speed things along and minimize downtime.
