Upgrading from 12.x to 15.x on 2800

[rpastrana]

Hello we have a 2800 appliance, and we'd like to upgrade from this IOS version:

c2800nm-adventerprisek9_sna-mz.124-15.T17.bin

To this one from 15.x, c2800nm-advsecurityk9-mz.151-4.M7.bin.

Is there any license we'd need to install to be able to do this ? I fear that maybe if we upgrade, the 2800 is going to have temporary licenses for 60 Days in version 15.x

Regards.

You should be able to upgrade with no issue. The only caveat that I ran into was that qos policies are calculated differently than with 12.4. It no longer uses max-reserved-bandwidth, and you have to put your bandwidth statement in the class default if you're nesting policies.

HTH,
John
