Firstly before upgrading IOS, you need to obtain the latest IOS version by logging on to Cisco Software Central at https://software.cisco.com/ and selecting your device type and version.
Please note that configure, price, and order Cisco products, software, and services. Available to partners and to customers with a direct purchasing agreement.
In my case I will be upgrading IOS image for Cisco Catalyst 2960X-24TS-L Switch. The downloaded c2960x-universalk9-mz.152-6.E2.bin file must be copied to your TFTP server as we will transfer the IOS image and perform our upgrade IOS via TFTP.
