I have a few Cisco Aironet 1200 AP's all running IOS version 12.2(12)JA.
I would like to upgrade to the latest version which I believe is 12.3.8-JED (GD) but I need to keep the configuration in place, I don’t want to lose any of it.
How can I do this? Which software do I need to download?
You won't be clearing the configuration if you follow the procedure. There's another separate the procedure to wipe of the appliance.
What do you mean by "pls explain me more about the images"?
