Any software is pron to have software upgrades either to fix a bug or a Security vulnerability or even for the fact the software has reached its end of life.
While Network devices and appliances are no exception, the upgrade process requires a lot of precautions and measures are taken to ensure that the upgrade process doesn't fail or cause problems post installation. Upgrading Cisco IOS is no exception. Care has to be taken to ensure that the newer version is tested on a test bed before deploying in the production network especially if we are talking core network switches and routers.
