CallRouter upgrade procedures

CallRouter pre-upgrade preparation

Pre-upgrade preparation is an integral part of the upgrade process.

Perform the following on the CallRouter to assist in recovery in the event of a catastrophic
upgrade failure:

1. Backup the Cisco Systems, Inc. registry key. See 

2. Backup the ICM/bin directory (for Common Ground upgrade only).

CallRouter Technology Refresh upgrade: side A/B

Note: The following procedure is used to perform a Technology Refresh upgrade on both sides
of the Router. When upgrading Side A use the procedure as is. When upgrading Side B, simply
replace “Side A” with “Side B” in the procedure.

Export the Cisco Systems, Inc. registry key from the production CallRouter and copy the resulting
RegUtil file to the new CallRouter. See 

 for additional information.

Run the ICM-CCE-CCHInstaller from the Unified CCE Installer DVD on the CallRouter.
Choose to apply any 9.x(x) Maintenance Release or 9.x(x) Engineering special; also apply the
automated hardening when prompted.

Specify if you want to perform a Technology Refresh or Fresh Install.
