Preupgrade Tools
During the preupgrade process, use the following tools as required:
-

You can download the User Migration Tool from Cisco.com by clicking ICM User Migration Tool Software.
-
Regutil Tool—Used in Technology Refresh upgrades, the tool exports the Cisco Systems, Inc. registry from the source machine during the preupgrade process. The output of the tool is required on the destination machine when running the Unified CCE Installer during the upgrade process.
You can download the Regutil Tool from Cisco.com by clicking Contact Center Enterprise Tools.
