Chapter3 Upgrading CiscoUnity Connection

Prerequisites for Upgrade

2. If you are upgrading during non business hours, run the following command on the standalone server

or the publisher server to speed up the upgrade process:

utils iothrottle disable

If you are upgrading during a maintenance window, you can speed up the upgrade by disabling the

throttling. This decreases the time required to complete the upgrade but affects Unity Connection

performance.

Caution You cannot disable throttling during the upgrade process. If you want to disable the throttling process,

you must first stop upgrade, disable throttle, and restart the Unity Connection server. Once the server is

active again, begin the upgrade process.

3. (Unity Connection 8.6 only) Install the licenses on the existing Unity Connection 8.6 servers before

you upgrade to Unity Connection 10.x server. While upgrade, the legacy license information is

uploaded in Unity Connection database. For more information, see the Migrating Licenses from

Unity Connection 8.6 and Earlier Releases, page6-3 section.

4. (Unity Connection 7.x only) Unity Connection version 7.0(1) and 7.1(2) cannot be directly upgraded

to Unity Connection 10.x and higher versions. If you are currently running versions earlier than

Unity Connection 7.1(3), you first need to upgrade to an intermediate version of Unity Connection

7.1(3). For information on supported upgrades, see the “Supported Cisco Unified Communications

Manager Upgrades” section of Cisco Unified Communications Manager Software Compatibility

Matrix at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr.html.
