Note: In Hosted Unified ICM/Contact Center environments, the NAMs and CICMs can beupgraded separately and in any order, provided that NAM/CICM compatibility is adhered to.NAM and CICM systems must either be at
the same version, or only one version apart. Forexample NAM could be at 8.0(x) and the CICM at 7.5(x) (or vice versa).
Note:The ICM-CCE-CCHInstaller checks if the following End of Life (EOL) components areinstalled in the machine, before upgrading it.
These EOL components are removed from the machine by the Installer, after confirmation fromthe user (excluding the Application Bridge Server which must be removed manually by runningPeripheral Gateway Setup after the upgrade and removing the Application Bridge Servercomponent). The components that are EOL in Release 8.0(1) are:
