Upgrading to a New Software Release
An upgrade is an order placed for a Cisco IOS® feature set that contains more functionality than the one
that you are replacing. And upgrade is not an update. An update consists of installing a more recent
version of the SAME feature set. Exception— If a feature set has been made obsolete, the next, closest
feature set, on a more recent release, will be considered an update.
For general information about upgrading to a new software release, refer to the Cisco IOS Upgrade Ordering
Instructions on Cisco.com.
