Note	Please review all sections in this document pertaining to installation before you install this Service Update (SU). Failure to install this SU as described may result in inconsistent Cisco Unified Communications Manager behavior.

This 11.5(1)SU8 ReadMe file contains important information about installation procedures and resolved caveats for Cisco Unified Communications Manager release 11.5(1)SU8. This SU can be applied to Cisco Unified Communications Manager and Session Management Edition.

Note	Before you install Cisco Unified Communications Manager, Cisco recommends that you review the Important Notes for information about issues that may affect your system.

The following sections comprise the system requirements for this release.

Server Support

In this release, you cannot install or run Cisco Unified Communications Manager on server hardware; you must run these applications on virtual machines. Please refer to the “Hardware” section of the Upgrade and Migration Guide for Cisco Unified Communications Manager and the IM and Presence Service, Release 11.5(1) for additional details:

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/upgrade/11_5_1/cucm_b_upgrade-guide-cucm-115.html

Uninterruptible Power Supply

Ensure that you connect each node to an uninterruptible power supply (UPS) to provide backup power and protect your system.

Caution

Failure to connect the Cisco Unified Communication Manager nodes to a UPS may result in damage to physical media and require a new installation of Cisco Unified CM.

This SU is a cumulative update that incorporates all of the fixes and changes from Cisco Unified Communications Manager 11.5(1) through 11.5(1)SU7 along with additional changes that are specific to this SU.

Note

You can only install this SU on Cisco Unified Communications Manager Release 8.6x, 9.x, 10.x, 11.0(1x), 11.5(1) through 11.5(1)SU7, or any 11.5(1)ES from 11.5.1.11001-2 to 11.5.1.18126-1. Upgrades from any earlier supported versions require a PCD migration. If upgrading from a version prior to 11.x, make sure you have obtained the appropriate licenses. This SU should not be installed on a Business Edition 3000 server.

For a list of all supported upgrade paths and the supported upgrade method, please see the Compatibility Matrix at:

http://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-device-support-tables-list.html

Caution

Please note that if you install an SU it may contain fixes that are not included in the newer Unified CM releases. For example, a fix in the latest 11.5(1)SU, 11.5(1)SU8, may not be included in 12.0(1) because the fix was not available prior to the release of 12.0(1). In this example, an SU or ES on the 12.0(1) branch may be required to retain the same fixes.

• To minimize call-processing interruptions during the upgrade process, register all devices to servers that are running the same version of Cisco Unified Communications Manager software. Make sure that you register all devices to the backup Cisco Unified Communications Manager server or to the primary Cisco Unified Communications Manager server, but not to both the backup and primary servers.

Warning for Upgrades to 12.0(1)

Warning

This SU adds support for Extension Mobility Login Simplfication using Headset. This feature is not found in CUCM 12.0(1) as that version was released prior to development of this feature. Upgrades from this SU to any 12.0(1) are not allowed and will not be displayed as valid upgrade options. Customers migrating from this SU should choose 12.5(1)SU3 or higher as their target upgrade.

Warning for Upgrades to 12.5(1)

Warning

This SU adds support for Extension Mobility Login Simplfication using Headset. This feature is not found in CUCM 12.5(1) prior to 12.5.(1)SU3 as those versions were released prior to development of this feature. Upgrades from this SU to any 12.5(1) version earlier than 12.5(1)SU3 are not allowed and will not be displayed as valid upgrade options. Customers migrating from this SU should choose 12.5(1)SU3 or higher as their target upgrade.

Firmware Upgrade Issues

For all SCCP and SIP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(2)SR1 or later. Refer to the Firmware Versions of this document to determine the firmware load provided in this SU.
