Installation, upgrade, and migration

This section contains information about the following topics:

Installation

No changes.

For more information, see Installing Cisco Unified Communications Manager, Release 9.0(1).

Upgrade

This section contains the steps to upgrade Unified CM and IM and Presence properly. Depending on your server setup, you can perform a standard or refresh upgrade.

Software version restrictions

From Release 9.0(1) onward, Cisco Unified Communications Manager (Unified CM) and IM and Presence Service software versions must match. For two software versions to match, they 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 CM Release 9.0.12.30000-2, but it is not compatible with Unified CM Release 9.1.1.10000-3. Similarly, Unified CM Release 8.6.2.10000-6 is not compatible with IM and Presence Release 9.0.1.10000-9.


Note


You cannot upgrade IM and Presence to Release 9.0(1) unless Unified CM is running Release 9.0(1) on the active or inactive partition. You must upgrade Unified CM 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 IM and Presence Release 9.0(1) 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


Note


The order in which you upgrade Unified CM and IM and Presence is very important.

  • Unified CM Release 8.6.x to Unified CM Release 9.0(1)
  • Cisco Unified Presence Release 8.6(4) to IM and Presence Service Release 9.0(1)

For standard upgrades, you must perform the upgrades in the following order:

  1. Upgrade the Unified CM publisher node.
  2. Upgrade the IM and Presence publisher node and the Unified CM subscriber nodes.
  3. Upgrade the IM and Presence subscriber nodes.
  4. Switch versions on the Unified CM publisher node.
  5. Switch versions on the IM and Presence publisher node and Unified CM subscriber nodes.
  6. Switch versions on the IM and Presence subscriber nodes.

Refresh upgrade order

The following upgrade paths are refresh upgrades:
  • Unified CM Release 8.5 and earlier to Unified CM Release 9.0(1)
  • Cisco Unified Presence Release 8.6(3) and earlier to IM and Presence Service Release 9.0(1)

For refresh upgrades, you must perform the upgrades in the following order:

  1. Upgrade the Unified CM publisher node
  2. Switch versions on the Unified CM publisher node.
  3. Upgrade the IM and Presence publisher node and the Unified CM subscriber nodes.
  4. Switch versions on the IM and Presence publisher node and Unified CM subscriber nodes.
  5. Upgrade the IM and Presence subscriber nodes.
