Although PGs are supported back two previous versions, to eliminate defects and add feature enhancements, the PGs
should be upgraded to the same version as the Central Controller. In addition, to minimize upgrade complications Cisco
recommends all components be at the same version prior to performing the upgrade.

Hosted Note: Assure Central Site PGs are the first PGs to be upgraded. All other sites can be subsequently upgraded due
to the sheer volume of PGs that are involved.

An equally important consideration for hardware compatibility requirements are those derived from the Microsoft
operating system and system software (most notably SQL Server 2000). Note that the Unified ICM/Unified CC solution
requirements outlined in this document match and in some cases exceed like requirements from Microsoft. For example,
while Microsoft SQL Server 2000 Enterprise Edition is not technically required (over SQL Server Standard Edition) with
a total of 4GB of physical memory and four or fewer processors, there are mission critical, high database load scenarios
where Enterprise Edition is suitable with the Unified ICM/Unified CC application. (Because Cisco performs all SQL
Server Enterprise Edition qualification on Windows Server 2003 Enterprise Edition, the latter is likewise required
whenever SQL Server Enterprise Edition is itself deployed.) Details are covered in

Additional important upgrade information follows:
A Unified ICM/Unified CC system is always upgraded from a prior release starting with the central controller
(Router and Logger) servers.
Upgrades of duplexed systems are typically done one “side” at a time.
As with any major release upgrade, Release 7.0(0) requires that the HDS systems be themselves upgraded to
coincide with the Logger to which they communicate.
Peripheral Gateway (PG) nodes are typically the last servers to be upgraded; the 7.0(0) upgrade will support
4.6.2 PGs through the upgrade transition, but all PGs must be running a minimum of release 5.0(0) for a fully
supported system configuration. (Release 7.x(x)) PGs are strongly encouraged, allowing the customer to take
advantage of several key PG enhancements made in the area of supportability, scalability, and feature support.)

advantage of several key PG enhancements made in the area of supportability, scalability, and feature support.)
Unified ICM Hosted and Unified CC Hosted customers may, as with prior major releases, upgrade their NAM
and CICM servers in either order to best suit their operational requirements. Also like prior releases, however,
the NAM-to-CICM protocol support inherent in the Hosted Edition software supports only a single major back-
level release. For Unified ICM/Unified CC Hosted 7.0(0) , this means the interface opposite that being
upgraded must itself be at release 7.0(0) (or later).

level release. For Unified ICM/Unified CC Hosted 7.0(0) , this means the interface opposite that being

The documented procedures for upgrading to Unified ICM/Unified CC Release 7.0(0) require a starting baseline
of ICM/IPCC 5.0(0) or 6.0(0), running on the Microsoft Windows 2000 Server operating system (SP4) with
Microsoft SQL Server 2000 (SP3a or SP4). Upgrade customers currently deploying releases earlier than release
5.0(0) will need to provide a transitional upgrade to 5.0(0) or 6.0(0) as a staging release. This step will require
database migration from the earlier release to 5.0(0)/6.0(0), and for that reason the upgrade requires
stabilization on the transitional release and is thus not a multi-step process accomplished in a single
maintenance window.

Microsoft Windows 2000 Update Rollup 1 for Service Pack 4 is supported by the various components of Cisco
Unified ICM/Unified CC 7.0(0) SR1 or later during the upgrade period. Update Rollup 1 is an elective add-on
to SP4 that is supported where Windows 2000 itself is supported.
