I wanted to know if someone could explain to me the steps needed to upgrade an ios.I've looked on the internet but i can't find any good informaiton.I have the TFTP software but other than that i don't know how to proceed.Any help would be greatly appreciated and thanks in advance
Before you start the actual upgrade can I ask the following questions please.
1. What equipment are you planning to upgrade the IOS on? Switch/Router and what model?
2. What IOS version is currently on this equipment?
3. How much DRAM and Flash memory does your equipment currently have?
4. What IOS version are you planning on upgrading to?
5. What size is this IOS version?
These questions should be answered prior to starting any upgrade as you need to ensure that your Router/Switch has enough resources to run the new IOS version.
