I am having issues pushing out IOSs to my network. I want to have CiscoWorks do it because I have over 300 Cisco Switches on the network to include 3750, 3560 and 2950s. The problem I am having is that CiscoWorks will not delete the old IOS to make room for the new one. I have scoured the options but I am not seeing how to get it to delete the old IOS. Does anyone have any advice?
