System Upgrade
This chapter discusses in detail the upgrade sequence for all of the IP telephony components that are configured in various deployment models for Cisco Unified Communications System Release 9.0(1).
Upgrade procedures for individual IP telephony components are not described in this document as they are available in individual component upgrade product documents.
 Note | The following upgrade strategies are recommendations only. No formal upgrade testing was done for the UC 9.0 system release. |
Note | Many of the IP telephony component names have changed as part of Cisco Unified Communications System releases. The latest product names are used in this document, even when referencing products from previous releases. |
IP Telephony Deployment Models
The upgrade procedures in this document are tailored for each deployment model in the IP telephony test environment, because each site includes different components.
Unified Communications Manager IP Telephony Models
This section provides the upgrade procedures for the various IP telephony components in the enterprise deployment models.

IP Telephony Component Upgrades
This section describes the following upgrade strategies for IP telephony components:
- Single-stage upgrade—Recommended for small single-site or multisite installations.
- Multistage system upgrade—Recommended for medium or large single-site and medium multisite installations.
- Multisite Migration—To upgrade large, multisite IP telephony installations to the Cisco Unified Communications System release set using the multisite migration upgrade strategy, you can use either the single-stage or multistage system upgrade procedures listed in the respective sections.
See System Upgrade Planning for detailed information about these upgrade strategies and see System Upgrade Preparation 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 System Upgrade Planning.
The upgrade paths that are available for upgrading IP telephony components are defined in System Upgrade Paths to Cisco Unified Communications System Release 9.0(1) in System Upgrade Planning.
When performing the upgrade of each component, see the product-specific upgrade document for detailed information. See the Related Documentation section for a list of URLs for component-specific release notes and installation and upgrade documents.
Single-Stage Upgrade
The single-stage upgrade process is recommended for small single-site and small multisite installations. This upgrade process can be performed in a single maintenance window, which allows you to upgrade components in a relatively short time and with no loss of functionality.
See System Upgrade Preparation for the software release versions of the components involved in the upgrade. Based on your environment and the base release set deployed in your network, upgrade the components in the order listed in the following table.
Upgrade Order for Base Release Set 8.6(1) |
|
|---|---|
|
Cisco Catalyst 6509/35241 (access switch) |
|
|
Cisco Unified Communications Manager cluster (Cisco Unified IP Phones, Cisco Catalyst 6500/6000 Gateways, Cisco IP Communicator, and Cisco ATA186/188/187 analog telephony adapters are upgraded with cluster) |
|
|
Cisco Unified Communications Manager IM and Presence Service |
|
Cisco Communications Media Module |
10 |
Cisco VG30D (analog phone gateway) |
12 |
|
SCCP/ SIP / H.323/ H.3202 Video Endpoints |
|
|
Cisco Unified Videoconferencing Gateway3 and Cisco Unified Videoconferencing System MCUs |
|
Multistage System Upgrade
A multistage system upgrade is the recommended approach for medium and large single-site and medium multisite installations. In this upgrade process, components are grouped 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 networks being upgraded. For smaller networks, several maintenance windows may be collapsed into a single maintenance window. Additional stages may be necessary for larger sites.
After each maintenance window and before initiating the next upgrade stage, we recommend that you verify that the operation of all basic and critical call types remains unaffected. We also recommend that you maintain a list of the components that have been upgraded and the ones yet to be upgraded.
If you are upgrading from the following base release set:
- Cisco Unified Communications System Release 8.6(1) to Release 9.0(1)—You will be running Unified CCX 8.5(1) SU1 and Unified Communications Manager Release 8.6(1a). You can directly proceed with the upgrade recommendations listed below
Cisco recommends the following two upgrade options:
- Same Maintenance Window—You can upgrade all the call processing components first and Unified CCX 8.5(1) next in the same maintenance window. Be aware that time estimates for this option are approximately 16 hours.
- Different Maintenance Windows—You should upgrade Unified CCX to Release 9.0(1) before upgrading Unified Communications Manager Release 9.0(1).
- Multistage System Upgrade Order for IP Telephony Components from Release 8.6(1) to 9.0(1)
