To obtain compatibility informtion for Releases 11.5(1)SU5 and later, refer to Compatibility Matrix for Cisco Unified Communications Manager and the IM and Presence Service 11.5(1)SU5 - SU7 at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/compat/11_x/cucm_b_compatibility-matrix-cucm-imp-1151su5-su7.html.

Notes About Engineering Specials (ESs), Service Updates (SUs), And Windows Service Release (SR) Upgrades

If you run a Linux or Windows Engineering Special (ES), a Service Update (SU), or a Windows Service Release (SR) for any version listed in the “Direct upgrade” tables, you can also upgrade to the target version for that section.

If you install an ES, it may contain fixes that are not included in newer releases. For example, a fix in the latest 10.5(1)es, 10.5(1.32xx-x), may not be included in 10.5(2x) because the fix was not available prior to the release of 10.5(2x). In this example, a later ES on the 10.5(2x) branch may be required to retain the same fixes.

Restricted and Unrestricted

Cisco Unified Communications Manager and Cisco Unified Communications Manager IM and Presence Service are available in both US Export Restricted and US Export Unrestricted (UNRST). The Restricted version contains full encryption capabilities. The Unrestricted version contains fewer encryption capabilities.

The US Export Restricted release has always been available from Cisco. A sample file name for US Export Restricted would be UCSInstall_UCOS_#.#.#.#####-#.sgn.iso.

The US Export Unrestricted UNRST release complies with import /export restrictions to various countries and is available in limited markets. A sample file name for US Export Unrestricted would be UCSInstall_UCOS_UNRST_#.#.#.#####-#.sgn.iso.

UNRST releases support fewer encryption capabilities and are classified as US export unrestricted. UNRST releases are intended for customers for which US Export and/or Foreign Import Encryption Regulations apply.

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

Long-Life Releases

Long-Life Releases are the final planned releases on a major train and will be the last releases to go End-of-Support on a major train. Customers planning to remain on one version of code for an extended period of time should select a Long-Life Release for their deployment.

Note	"Major" releases are differentiated by the first digit of the release number; 9.x, 10.x are examples of "major" releases.
