Do I need to obtain license keys/files when upgrading a 2851 to IOS 15.x? I'm getting a bit confused seeing the documentation that says 1) IOS has gone to a universal image and 2) that feature sets are unlocked based on the installed license.
I was able to download a feature specific IOS image for the 2851 and it did not bother me about licensing upon boot up.
I read one post on here that stated 2800/3800 series (G1) do not have to worry about the licensing piece and that it's just 2900/3900 series (G2) hardware that require it.
I've a planned migration from IOS 12 to 15 on ISR G1 , my customer worry about licensing issues, is there a Cisco document specifying that ISR G1 doesn't use Universal Image and licenses to activates features ?
