XXXXXXXXXXX: Collaboration Migration Plan
The Network Guys, Inc.
Created on OCT 27,2014
Summary
This document serves as a resource for those individuals involved in the planning and execution of the migration for the CUCM, Unity, UCCX, and CIMP upgrades on virtualized Cisco UCS platforms. This document will also address the migration steps necessary for voice gateway, as well as any third party integrations.

Detailed Migration Tasks
The migration tasks identify current environment variables as well as lays the foundation for where the migration is going and how it will get there. The following topics are not in execution order, which allows the implementer the flexibility to arrange work tasks to suit the needs of the client.
Prime License Manager (PLM)
PLM is the new centralized licensing management software, co-resident with the CUCM Publisher server (no separate VM required) and hosts the licenses for CUCM, IM&P*, CUC and CER.
*IM&P s technically licensed as a part of CUCM, but is called out here for completeness.
Device Owner User ID Associations
To ensure the proper number of licenses are migrated based on currently installed licensing and current device usage, we will need to associate the Owner User ID to each device which belongs to an individual.
Migration Support
The Global Licensing Operations (GLO) Team is available 24 x 7 x 365 and has knowledgeable agents that can help.
Process your request and route it to the team best able to assist you. Expect a response within 48-72 hours.
Remember: Product licensing has a grace period from the time that users are configured on the system. For Unified CM and Unity Connection, the grace period is 60 days.
To obtain migration support, select one of the following options:
Open your service request through the web: https://tools.cisco.com/ServiceRequestTool/scm/mgmt/case
Open any service request through licensing@cisco.com (include Cisco.com user ID)
Open a service request by telephone using country-specific numbers: http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html

Voice Gateways
Voice gateways convert from one voice network to a different voice network. The bridge the gap between different networks, or similar networks with different operating parameters. The most common gateways connect your voice network to the PSTN, and connect your VoIP network with your legacy analog devices.
PSTN Voice Gateways
The PSTN voice gateway has one or more connections (aka circuits or lines) to a telephone company (aka telco), and connects to your VoIP network.

Cisco Unified Contact Center Express (UCCX)
UCCX is primarily offers sophisticated call routing and comprehensive contact management capabilities. It includes an embedded reporting solution that offers a comprehensive view of contact center statistics.
For a performance boost, you will want to disable disk IO throttling prior to the upgrade, and then re-enable it post upgrade.

This will be a two step process. We will upgrade to version 9.0(2)SU2 using Cisco’s osadministration web interface , verify inactive version, switch versions
We will then upgrade to version 10.5(1)SU1 using Cisco’s osadministration web interface , verify inactive version, modify ESXI host, and switch versions, and apply Bash Environment patch if needed (see CSCur02861). We will confirm this by running 'show packages active bash' before and after the patch.
Agents will upgrade their version of clients on the next login.

Upgrading to 10.5(1)
Upgrading to 10.5(1) starts with downloading the ISO file from cisco.com, and then hosting it on an FTP server for CUCM to download locally. The Publisher node is upgraded first, then rebooted in to the new version, followed by upgrading the Subscriber node second and rebooted in to the new version.
After the upgrade to CUCM, the endpoints should not change nor require a change, nor shall Unity or CER. Though, a test plan should be executed to validate the upgrade.

Important Notes
Uninstalled PAKs
Unused PAKs need to be installed on respective applications before upgrade to PLM.
Setting Manual MAC Addresses
Cisco recommends converting dynamically created MAC Addresses for licensed servers to statically defined MAC Addresses.
Removing PLM from CoRes Servers
“In a coresident deployment, you have the option to remove Cisco Prime License Manager if it is not being used. For example, in a Cisco Unified Communications Manager cluster, Cisco Prime License Manager is installed on publisher nodes and subscriber nodes. Since the Cisco Prime License Manager only needs to be active on a single node to manage the licensing of all nodes, you may choose to remove Cisco Prime License Manager from the nodes where it is inactive.”
Source: PLM User Guide
To conserve system resources we will remove PLM from the CUCM Subscriber, CUC Publisher, and CUC Subscriber after the upgrade.
Device Owner User ID Associations
To ensure the proper number of licenses are migrated based on currently installed licensing and current device usage, we will need to associate the Owner User ID to each device which belongs to an individual.

The Global Licensing Operations (GLO) Team is available 24 x 7 x 365 and has knowledgeable agents that can help.
Process your request and route it to the team best able to assist you. Expect a response within 48-72 hours.

Third Party Application Integrations
In some cases, the phone system is integrated with third-party (non-Cisco) software and/or hardware systems, which need to be managed during a migration to new hardware, software, as well as renaming and re-IP Addressing.
Changes and Enhancements
During the migration, there may be opportunities to introduce enhancements to the system, and in some cases changes will be necessary to increase project success. In either case, all changes and enhancements are documented below.
Setting Device Owner User ID, Line Appearance Associations and End User Control
Setting the device owner user ID allows the Prime License Manager (PLM) accurately account for device usage and application of the appropriate license level.
Setting the Line Appearance Association allows Jabber to accurately determine a user’s status: whether they’re on the phone or not.
Setting the End User Control does two things: allows the user to manage the device in Self Care Portal and Sets the user’s primary extension.
We will use BAT’s Phone Export All Details feature, modify the data to include Owner User ID information, and then use BAT’s Phone Import and Override Configuration feature to apply the changes.
We will use BAT’s User Line Appearance Update feature to set Line Associations.
We will use BAT’s User Update User with the ignore character supplied such that we only modify the Controlled Device and the Primary Extension.
In the event that BAT cannot be leveraged for this task, a manual update may be required.
