Hi Support,
I am having 3 2960 switches in which 2 are having IOS version 12.2(55)SE3 and one is having version 15.0(2a)EX5.So I was trying to upgrade the IOS of the other two switches and I was able to download IOS from cisco page but I'm a bit nervous because someone told me that if I upgrade to this version c2960s-universalk9-mz.152-2a.E1.bin my current license will be void. Kindly anyone please help me.Below is the license info from the switches.I'm trying to upgrade because routing command is only working in my switches with version 15.0(2a)EX5 switches.
