Licensing for IOS 15.x on 2851 routers

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.

Thanks!

The ISR G1 routers do not use an unversal images. Things remained the way they were before, with the addition that the product is end of sale now

Excellent.  It's just a matter of upgrading the RAM and CompactFlash to run 15.x (which we are doing).  Thanks!
