Hey Danny,
This is a supported "direct' upgrade path, but I would consider NOT going
to 7.1(5)xx unless there is a critical feature you require The current
recommended version that most people here have found very stable is
7.1(3b)su2. we have been running it for some time now without issue.
Supported Cisco Unity Connection Upgrades
Revised July 20, 2010
Caution With restricted and unrestricted versions of Connection software now available, download software or order a DVD carefully. Upgrading a restricted version to an unrestricted version is supported, but future upgrades are then limited to unrestricted versions. Upgrading an unrestricted version to a restricted version is not supported. (See also the "Cisco Unity Connection 7.1(5a)—Restricted and Unrestricted Versions" section.)
You can upgrade directly to Connection 7.1(5b) from many but not all versions of Connection 2.x and later. For information on whether you can upgrade directly to Connection 7.1, see the "Supported Cisco Unified Communications Manager Upgrades" section of the Cisco Unified Communications Manager Software Compatibility Matrix at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr.html.
You refer to the full version number of the Cisco Unified Communications Operating System that is currently installed on the active partition to determine upgrade support. The version can be viewed by running the CLI command show version active.
Full version numbers include the build number (for example, 7.1.5.10000-10); the software versions listed on the download pages on Cisco.com are abbreviated version numbers (for example, 7.1(5) ). In the tables of the "Supported Cisco Unified Communications Manager Upgrades" section of the compatibility matrix, full version numbers are listed in the System Version row.
Note Abbreviated version numbers for Connection and the Cisco Unified Communications Operating System are identical except that Connection 2.x versions correspond with 6.x versions of the operating system.
Do not refer to version numbers in any of the administration user interfaces because those versions apply to the interfaces themselves, not to the version of the product software installed on the active partition.
If you cannot upgrade directly from your current version to Connection 7.1(5b):
1. Find an intermediate version that is supported both for an upgrade from your current version and for an upgrade to 7.1(5b).
2. Upgrade to the intermediate version. See the applicable Reconfiguration and Upgrade Guide for Cisco Unity Connection at http://www.cisco.com/en/US/products/ps6509/prod_installation_guides_list.html.
3. Upgrade to Connection 7.1(5b). See the following section, "Upgrading to Cisco Unity Connection 7.1."
