Once the ICM system has been successfully tested, the remaining Admin 
Workstations may be upgraded and started.

Upgrade the Peripheral Gateways.

Peripheral Gateways may be as many as two releases lower than the Central 
Controller release. The Peripheral Gateways do not necessarily have to be 
upgraded during the same maintenance window as the Central Controllers. 
However, it is strongly recommended that they be upgraded within the same 
week as the Central Controllers.

ICM 4.6.2 PG's are compatible with ICM 6.0 Central Controllers subject 
to reporting limitations relative to features introduced in the newer 
version. Upgrade all components to the latest version to take advantage of 
the newest features.

It is recommended all operating system and ICM upgrade steps are 
completed, the historical data migration is complete, and the system is stable 
prior to performing a SQL upgrade.

Verify completion by looking at the recovery log on the Logger and the 
replication log on the HDS. 

In addition, verify the completion of the configuration transfer to the 
Router using the Router Router and Logger Logger logs; AW Update 
using the Update AW and Logger Logger logs; HDS data replication 
using the HDS Replication and Logger Recovery logs.

Upgrade MS SQL 7.0 SP3/4 to MS SQL 2000 SP3a. (See 

For ICM 4.6.2 to ICM/IP Contact Center Enterprise Edition, Release 6.0(0) 
upgrades only: Be aware that when you run ICM setup.exe, the automatic 
conversion of the registry keys (from GeoTel to Cisco Systems, Inc., and icr to 
icm) occurs before you gain access to the ICM Setup dialog.
