Upgrading to a New Software Release
An upgrade is an order placed for a Cisco IOS feature set that contains more functionality than the
feature set that you are replacing. An 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 is considered an update.
For general information about upgrading to a new software release, refer to the Cisco IOS Upgrade
Ordering Instructions on Cisco.com. Also refer to Appendix A, “Installing or Upgrading Cisco IOS
Software.”
