Cisco Cisco IPCC Web Option Installation Guide

Definition of Upgrade Steps

The upgrade migration of an ICM/IPCC system involves numerous steps. From your initial
software load, you must install/upgrade the operating system, the ICM software (and options),
the database software, and any required third party software.

Be aware that, for a period of time during the upgrade migration, the ICM/IPCC system runs
in a non-fault tolerant mode. In addition, network default routing takes place when both sides
of the Central Controller are “stopped” during the cross over (see the Test Plan section).

Testing must take place when the side A Central Controller is upgraded and running. The upgrade
team must then come to consensus on the success of the testing and make a “go” or “no go”
decision to proceed with upgrading the side B Central Controller.

If critical problems are encountered after upgrading side A, the upgrade team could decide to
restore the side A Central Controller to the old/prior release.
