IOS upgrade and Technology Packages licenses

[fuhrersk8]

                   Hello guys!

When upgrading a Cisco 2921 that already has UC and IP Base technology packages installed from version 15.0(1)M6 to version 15.1(4)M5 it is necessary to upload the licenses after the upgrade or licenses will remain the same?

Thanks in advanced!

The licenses will remain intact as long as you don't format the entire flash card.
