Chapter 3 Upgrading Cisco Unity 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, page
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.
