I currently have 4400 series and 2000 series controller which are running 4.2.176 code. I have purchased some 2112 and 2125 but they have come with 5.2 code, is there a way to downgrade them to 4.2.176? I haven't been able to find this code on the CCO. Reason I want to downgrade is because of the issue with the mobility anchors that want the same code on all WLC. Please help.
