not sure of the same switch planned for upgrade?

[baselzind]

i need to upgrade switch model WS-C2960C-12PC-L which is using  12.2(55)EX3 , when i looked over cisco for drivers the only version were 15 and higher and no mention of version 12 , so i was worried maybe the switch im looking over Cisco website is different?

Read the Release Notes carefully.
15.2(7)E1 should be fine.
