The following chapter describes important upgrade information for Cisco Unified Communications Manager Release 9.0(1) and the IM and Presence Service Release 9.0(1).

Software version restrictions

Unified Communications Manager and IM and Presence Service software versions must have the same major and minor release number. Major and minor release numbers are defined as follows:

9.x.y

where 9 = major release number, x = minor release number and y = maintenance release number.

For example, IM and Presence Release 9.0.2.10000-4 is compatible with Unified Communications Manager Release 9.0.12.30000-2, but it is not compatible with Unified Communications Manager Release 9.1.1.10000-3. Similarly, Unified Communications Manager Release 8.6.2.10000-6 is not compatible with IM and Presence Release 9.0.1.10000-9.

The software version of subsequent IM and Presence nodes that you upgrade must match all five version numbers of the first IM and Presence node that you upgraded.


Note


You cannot upgrade IM and Presence unless the upgraded release of Unified Communications Manager is already installed on the active or inactive partition. You must upgrade Unified Communications Manager before you can upgrade IM and Presence to the matching version.



Caution


If you use Platform Administrative Web Services (PAWS) Management to upgrade IM and Presence, do not attempt to upgrade and reboot to the current IM and Presence release if the active partition on Unified CM is running an incompatible software version. If you do, the upgrade will fail, as expected, but the failure will not be reported until near the end of the upgrade process. You will also experience system downtime when the system reboots.

The delayed upgrade failure notification applies only to upgrades that are performed with PAWS Management. If you perform the upgrade through Cisco Unified IM and Presence Operating System Administration or through the CLI, the upgrade failure notification is displayed at the beginning of the upgrade.


Upgrade order

The order in which you upgrade Cisco Unified Communications Manager (Unified CM) and IM and Presence is very important.


Note


Do not start to upgrade the IM and Presence publisher node until the upgrade of the Unified CM publisher node has reached a specified point. See the section Upgrade a Cluster for more information about determining the specified point in the upgrade.

Do not start to upgrade an IM and Presence subscriber node until the upgrade of the IM and Presence publisher node is complete.
