Each IM and Presence Service shipment comes with an installation DVD, which is required for all new installations of IM and Presence Service. The IM and Presence Service operating system and application software is installed from the installation DVD. For example, for new installations of IM and Presence Service software, use the DVD that indicates this release of IM and Presence Service.
If you fresh install the unrestricted version of IM and Presence Service Release 10.0(1), you will not be able to later perform a fresh install of the restricted version of this software.

Cisco does not support downloading major IM and Presence Service software releases from Cisco.com, for example, IM and Presence Service Release 9.0(1). You can download from Cisco.com upgrade-only software images that are used to upgrade from a previous major software release to a subsequent software maintenance release or point release of IM and Presence Service. For example, you can download Cisco Unified Presence Release 8.0(2) or Cisco Unified Presence Release 8.6(1) from Cisco.com.
You must follow a specific order when upgrading Unified Communications Manager and IM and Presence Service. The order depends on the release from which you are upgrading. The preupgrade release determines the type of upgrade you must perform. There are two types of upgrades:
You can run this release of IM and Presence Service on a VMware virtual machine that is deployed on approved Cisco Unified Computing server hardware. For information about supported servers, see Hardware and Software Compatibility Information for IM and Presence Service on Cisco Unified Communications Manager. For information about the VMware licensing requirements, see the License Activation for Cisco Unified Communications on Cisco Unified Computing System Docwiki here: http://docwiki.cisco.com/wiki/License_Activation_for_Cisco_UC_on_UCS.
Recommendations for Release 8.0(x), 8.5(x), or 8.6(x) to 9.1(1) upgrades
Before you perform an upgrade, this service may be disabled on the cluster (which only runs on the Publisher node). This action will ensure that user-initiated changes from the corresponding Unified Communications Manager system during the upgrade do not compromise the upgrade process. The changes are reconciled when the IM and Presence Service Sync Agent is restarted in either the current or newer version.
Switch versions and restart the publisher node before you begin a switch version and restart on the subscriber nodes. If the IM and Presence Service Administration GUI is operational on the publisher node, it is safe to initiate a switch version and restart on the subscriber node.
Services on the publisher will not start until the subscribers are switched and restarted, and replication is successfully established on that cluster.
Contact List Size
The default maximum value is 200; however, you can use higher value or specify the value as 0 to set it to an unlimited value. After you perform the upgrade, check that the contact list size for users has not reached the maximum value. If you have a large number of contacts per user, the number of users that an IM and Presence Service node supports is reduced.
