I know that this requires scripting and use of the API, but I haven't figured out where to start. I populate extension attributes for SSID, State, and City. I'd like to populate a separate extension attribute to track the previous SSID, State, and City if they've changed. I only want to track a single change, so I imagine this only needs an EA and a correlating "previous" EA.
Any guidance any of you can provide would be great. TIA!
