Upgrading IPT Software Components
This topic discusses in more detail the upgrade sequence for all the IP telephony (IPT) components configured in specific deployment models for Cisco Unified Communications Release 5.0.
Upgrade procedures for individual IPT components are not described in this document, since they are available in individual component upgrade documents. See the Related Documentation section at the end of this topic for the appropriate upgrade documents and their URLs.
This topic contains the following sections:
IPT Deployment Models
Upgrade procedures in this document are specifically tailored for each of the deployment models in the IPT test environment, since each of the sites includes different components.
Detailed information about IPT deployment models that are tested for Cisco Unified Communications Release 5.0 is available in the System Architecture Reference Manual for IP Telephony at: http://www.cisco.com/univercd/cc/td/doc/systems/unified/unified1/starmipt/index.htm
Listed below are the various deployment models possible in the Cisco Unified Communications IPT test environment:
•
Multi-Site Centralized and SRST
Compare the above deployments to your specific deployment to best understand the upgrade process that is applicable in your environment.
This section provides the general upgrade sequence for the various components in the different deployment models. More detailed upgrade procedures are discussed later in this topic.
Single Site
In the IPT single site model, upgrade the components in the following order:
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
11.
12.

Multi-Site Centralized and SRST
You must first upgrade central sites followed by the remote SRST sites in the multi-site centralized model.
In each central site, upgrade the components in the following order:
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
11.
12.

In each remote site, upgrade the components in the following order:
1.
2.
3.
4.
5.
6.
Note
7.
Multi-Site WAN Distributed
The multi-site distributed model includes several Cisco CallManager cluster sites inter-connected by ICT or H.323 trunks.
You should treat the upgrade of each site as a separate stage in the overall upgrade process.
Upgrade the components within each site in the following order:
1.
2.
3.
4.
5.
6.
7.
8.

Upgrading IPT Components
This section describes the following upgrade strategies for IPT components:
•
•
•
See "Planning Your System Upgrade" for detailed information on the above upgrade strategies and Chapter 2, "Preparing for System Upgrade" for the software release versions of the components involved in the upgrade. For more information about the number of seats in these various types of sites, see Table 1-1 the Summary of Upgrade Strategies table in "Planning Your System Upgrade."
Single Stage Upgrade
The Single Stage upgrade process is recommended for small single/multi-site installations and can be performed in a single maintenance window. This enables you to upgrade all the components in a brief period of time with no loss of functionality.
North America IPT Components
In a North America IPT environment, you should upgrade the components in the order listed in Table 3-1.
EUEM IPT Components
In an EUEM IPT environment, you should upgrade the components in the order listed in Table 3-2.
Multi-Staged System Upgrade
A Multi-Staged System upgrade is the recommended approach for medium/large single-site and medium multi-site installations.
In this upgrade process, components are grouped together for upgrading in several stages or maintenance windows. Within each maintenance window, there is a recommended order for upgrading each component.
The grouping of the components into the stages may vary depending on the size of the network being upgraded. For smaller networks, one or more separate maintenance windows may be collapsed into a single maintenance window. Additional stages may be necessary for larger sites.
After each maintenance window, we recommend that you verify that the operation of all basic and critical call types remains unaffected, before you initiate the next upgrade stage listed.
See Chapter 2, "Preparing for System Upgrade" for the software release versions of the components involved in the upgrade.
North America IPT Components
In a North America IPT environment, the stages and the components you should upgrade during each stage are listed in Table 3-3:
