Phase 2- Management Upgrades

Single Maintenance Window Procedures and Sequence

This phase includes upgrades of all the Cisco HCS Service Fulfillment and Service Assurance components. Cisco recommends that you complete this phase in one upgrade window. This topic describes the recommended sequence of tasks.

Alternatively, you can upgrade this phase over multiple maintenance windows. For more information, see Multiple Maintenance Windows Upgrade Sequence.


Important
A complete provisioning freeze is in effect during the upgrade maintenance window, but interruptions to Cisco HCS end-user Unified Communications application services are not expected.

When you perform Phase 2 in one maintenance window, upgrade the components in the following order:

  1. Install Prime Collaboration Assurance.

  2. Upgrade Cisco Hosted Collaboration Mediation Fulfillment (HCM-F).

  3. Upgrade Service Fulfillment and Service Assurance domain managers. You can upgrade or migrate these components in parallel.

    1. Upgrade Cisco Unified Communications Domain Manager (Unified CDM) platform and software.

    2. Upgrade Cisco Unified Contact Center Domain Manager (Unified CCDM).


Note

You can reduce the time it takes to upgrade Unified CDM by performing backup activities before the upgrade maintenance window. You can reduce the time for upgrade and backup by running node upgrades in parallel (a process that includes a backup) with the following CLI command:

cluster upgrade media/platform-install-1.2.0-<version>.iso fast

Another alternative is to use VMware snapshots for your backup, if reducing the length of time for the upgrade is a primary consideration. Consider the following when using VMware snapshots to back up Unified CDM:

  • Cisco cannot guarantee that a VMware snapshot can be used to successfully restore Unified CDM or any Cisco HCS Management application. If you cannot restore the application from a snapshot, your only recourse is to reinstall the application.

  • When the backup is complete and you do not need the VMware snapshot for restore activities, delete the snapshot immediately to preserve LUN space.

For more information about the risks of using VMware snapshots, see the “Backup and Restore” chapter in the Cisco Hosted Collaboration Solution Maintain and Operate Guide.

You are not required to complete data migration to Prime Collaboration Assurance during the single maintenance window.

Upgrade Cisco Hosted Collaboration Mediation Fulfillment

Upgrade Overview

The following Cisco HCM-F upgrade paths are supported:

  • 11.5(x) to 12.5(1) and later Service Update releases

  • 10.6(x) to 12.5(1) and later Service Update releases

Before you begin to upgrade from 11.5(1) release to 11.5(4)SU1, it is mandatory to install the hcs.CSCvb86072-1-1151patch.cop file on HCMF.

Before you begin the upgrade process, obtain the appropriate upgrade file using one of the following methods:

  • Use the Product Upgrade Tool (PUT). To use the PUT, navigate to https://tools.cisco.com/gct/Upgrade/jsp/index.jsp. Enter your Cisco contract number (Smartnet, SASU or ESW) and request the DVD set.

  • Purchase the upgrade from Cisco Sales if you don't have a contract for Cisco HCS.

In general, perform the following tasks to upgrade Cisco HCM-F:

Resetting Cisco HCM-F Service Parameter Defaults After Upgrade

The Cisco HCM-F upgrade process automatically resets some service parameters to their default value. If you changed the default value for any of these service parameters before upgrading, use the following command to reset the value after upgrading:

set hcs <service-name> <service_parameter_name>

The following service parameters are affected:

  • Link auto-vm-linkage

  • Ucsmsync require-ucsm-certificate

  • Vcentersync require-vcenter-certificate

Service Fulfillment and Service Assurance Domain Managers Upgrade

Migrating from Prime Collaboration Assurance 11.x and Later Versions

To migrate the existing data from Cisco Prime Collaboration Assurance 11.x to 12.1, you must use the Data Migration Assistant tool. Follow the steps in the "Overview of Data Migration Assistant" topic in the Cisco Prime Collaboration Assurance and Analytics Install and Upgrade Guide, 12.x : https://www.cisco.com/c/en/us/support/cloud-systems-management/prime-collaboration/products-installation-guides-list.html for detailed information.
