Sounds taking quite some risks here.</P><P></P></BODY></HTML> Thu, 10 Sep 2009 23:27:02 GMT https://community.cisco.com/t5/wireless/downgrade-wlc-software/m-p/1250767#M47773 Lucien Avramov 2009-09-10T23:27:02Z Re: Downgrade WLC software https://community.cisco.com/t5/wireless/downgrade-wlc-software/m-p/1250768#M47774 <HTML><HEAD></HEAD><BODY><P>Thanks for your inputs.</P></BODY></HTML> Mon, 14 Sep 2009 14:43:40 GMT https://community.cisco.com/t5/wireless/downgrade-wlc-software/m-p/1250768#M47774 forrestermu 2009-09-14T14:43:40Z
