Purpose: Issue resolves roaming issues we are experiencing among other caveats.
Impact: All wireless traffic could be impacted on Marshall Campus briefly. To limit impact the backup controller will be upgraded in advance and image will be predownloaded to access points. When production controller goes down the ap's will move to backup controller that was already upgraded. This will require a reload of ap so outage should be 5-10 minutes. When production controller is back up the ap's should migrate back to production controller with no other outage. I
Affected: All wireless traffic on Marshall Campus could be down.
