Note	To view the release notes for previous versions of Cisco Unified Communications Manager, choose the Cisco Unified Communications Manager version from the following URL: http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_release_notes_list.html

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 12.5(1)SU7a ReadMe file contains important information about installation procedures and resolved caveats for Cisco Unified Communications Manager release 12.5(1)SU7a. 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 12.5(1) for additional details:

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/upgrade/12_5_1/cucm_b_upgrade-migration-guide-125x.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 12.5(1) through 12.5(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 8.6(x) through 11.x, 12.0(1x), 12.5(1) through 12.5(1)SU7, or any 12.5(1)ES from 12.5.1.11001-1 to 12.5.1.18090-1. Upgrades from any earlier supported versions require a PCD migration. If you are upgrading from a version prior to 12.x, ensure you have the proper licensing prior to doing the upgrade.

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 an 11.5(1)SU, 11.5(1)SU6, 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.

For details about the features included in this release, refer to Release Notes for Cisco Unified Communications Manager and IM & Presence Service, Release 12.5(1) at:

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

In addition to the features listed in the Release Notes, the following changes were introduced in 12.5(1)SU7:

• Log4j upgrade to 2.17.2

In addition to the features listed in the Release Notes, the following changes were introduced in 12.5(1)SU4:

• Upgrade to JDK8

• Upgrade to Tomcat9

Compatibility between collaboration products is detailed at the following link. You must insure your versions are compatible before beginning your upgrade:

https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/unified/communications/system/Compatibility/CSR-Compatibility-Matrix-InteractiveHTML.html

Cisco provides the following guidance to help you successfully upgrade Cisco Unified Communications Manager software:

• 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 from 12.5(1)

Warning

There is an open caveat in the Upgrade Enhancements feature in all 12.5(1) releases, where the source version is prior to SU2, which could cause cluster upgrades to newer 12.5(1) versions to fail. Use the Bug Search Toolkit link below for more details on the conditions that cause the issue and possible workarounds: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvq22312

Warning for Upgrades to 14

Warning

This SU adds support for Meraki access points. This feature is not found in the CUCM 14 base release, as that version was released prior to development of this feature. Upgrades from this SU to any CUCM 14 versions lower than 14SU1 are not allowed and will not be displayed as valid upgrade options. Customers migrating from this SU should choose 14SU1 or higher as their target upgrade.

Warning for UCCE Environments

Warning

UCCE (Unified Contact Center Enterprise) Solutions where CVP was deployed and integrated with CUCM via UDP protocol, will be negatively affected by CSCwe31994. See the Caveats section for more information.

To view documentation that supports Cisco Unified CM Release 12.5(x), go to:

https://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-documentation-roadmaps-list.html

Before you upgrade the software version of Cisco Unified Communications Manager, verify your current software version.

To do that, open Cisco Unified Communications Manager Administration. The following information displays:

Cisco Unified CM Administration System version: x.x.x

Note	Apply this SU to all of your Cisco Unified Communications Manager servers, beginning with the publisher server and TFTP server

Refer to the Upgrade and Migration Guide for Cisco Unified Communications Manager and IM and Presence Service, Release 12.5(1) for detailed information about doing this upgrade:

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/upgrade/12_5_1/cucm_b_upgrade-migration-guide-125x.html

Note	Because the 12.5.1.18100-14 build is a non-bootable ISO, it proves useful only for upgrades. You cannot use it for new installations. You may however install with the base version 12.5.1.10000-22 and apply 12.5.1.18100-14 as a patch during the installation.

Release 12.5(1)SU7a is available in both restricted (which is the release type that has always been available from Cisco) and unrestricted versions of software to comply with import / export restrictions to various countries. The unrestricted version is available in limited markets. Please refer to the “Export Restricted and Export Unrestricted Software” section in the Understanding Upgrades and Migrations chapter, of the Upgrade and Migration Guide for Cisco Unified Communications Manager and the IM and Presence Service, Release 12.5(1) referenced above, for a more detailed description.

Note	Once installed, UNRST releases can never be converted or upgraded to releases which support full encryption capabilities

The file names and hash values you will use for this upgrade are:

Note	Revert the SU on all servers in the cluster in the same order in which you performed the installation.

Refer to the “Switch to Previous Version” section in the Upgrade Procedures chapter at Upgrade and Migration Guide for Cisco Unified Communications Manager and IM and Presence Service, Release 12.5(1) for detailed instructions on “Reverting to a Previous Version.”

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/upgrade/12_5_1/cucm_b_upgrade-migration-guide-125x.html
