ios upgrade 15.1 to 15.2

Hi all,

i'm trying to find information about the licesing of ios package.

I need to upgrade a C2911 from 15.1 to 15.2, the router have a permanent uc license, will be that license permanent also after the upgrade?

I'm not able to find documentation about when the license need to be reissued after an upgrade or not. I know that for maintenance release upgrade there are not problems but i'm not sure about minor upgrade.

regards

Hi leolaohoo,

Your licensing won't change because the IOS file is "universal".  What changes the license is a license key and this is stored somewhere else.

I found some documentation and it is always mentioned that the maintenance release do not need a software license

http://www.cisco.com/assets/cdc_content_elements/flash/ios/csa/csa_introduction.htm

end of part 6 of 9 it say specifically that maintenance upgrade don't need a new license

http://www.cisco.com/en/US/prod/collateral/routers/ps10616/white_paper_c11_556985.html

"However, migrating software images from one release to another (e.g. from 15.0(1)T to 15.0(2)T) does not require a new license."

Also, the training in the first link say that the UDI, associated with license, contains the router version information. So changing the IOS will change the UDI that will invalidated the license. What is not specifically written is what part of the version information contains the UDI: major? minor?

I upgraded our 2921 from 15.0 to 15.1M and I still retain my license.

Oh thx, this is a good information. There are so many documents and no one that explain well the upgrade process and when a new license is needed! I suppose only for major upgrade.
