Hi There,
Sounds like an interesting project. I can help you with it. Worked with those Zebra/WING APs, but not that much - for different reasons Cisco wireless solutions with APs and WLC happen more often for me. Do you have APs as a standalone boxes or managed by RF-switch or controller? Do you need upgrade only or any configuration changes as well?
I'll obviously need remote access, preferably CLI.
regards
