Hello, we currently have several client sites(about 50), using Aironet 1100's. We are using WEP, and everyone is authing to our ACS.
Would like to change everything over to WPA. What kind of issues could I expect...the clients connecting are constantly changing, so any and all Operating Systems, hardware platforms, wireless cards, wireless hubs, etc. will be connecting.
Is this irrelevant and as long as our cisco equip supports WPA then we are ok to change this? How difficult can a migration like this get?
