This will allow you to easily configure those settings after the upgrade is Parameter settings and evaluate the best settings for the combined cluster.

IM and Presence only are retained after an upgrade.Д¬isco recommends that before you begin an upgrade, you make a note of The User Assignment Mode parameter is the only enterprise parameter that is retained during upgrade. Unified Communications Manager only, with one exception. All enterprise parametersДЄnd cluster-wide service parameters that are common toД«oth Cisco Unified Communications Manager and IM and Presence Service retain the value specified on You need to be aware that not all parameter settingsДЄre retained during an upgrade to Release 10.0(1). As such, both types of nodes use the same settings forД®nterprise and cluster-wide parameters. IM and Presence Service, enterprise and service parameters are now sharedД«etween nodes in a cluster. That are supported, see the 'Supported Integrations' chapter in the Compatibility Matrix for Cisco Unified Communications Manager and IM and Presence Service.

The IM and Presence Service supports intercluster peers to clusters that are running different software versions. The maximum number of IM and Presence Service nodes in a cluster is 6.ДЇor more information, see 'Cisco Collaboration Solutions Design Guidance' at Support for Intercluster Peers

Number of servers in a cluster, including the Unified Communications Manager publisher node, TFTP server, and media servers, cannot exceed 21. The number of Unified Communications Manager subscriber nodes in a cluster cannot exceed 4 subscriber nodes and 4 standby nodes, for a total of 8 subscribers.

#CISCO CUCM 8.6 UPGRADE PATH INSTALL#

This section describes the limitations that apply when you install or upgrade Unified Communications Manager or the IM and Presence Service Service.Дo not install Unified Communications Manager in a large Class A or Class B subnet that contains a large number of devices. If such failures occur, you must restart the entire upgrade process for both Unified Communications Manager and IM and Presence Service Service clusters. Process will result in data migration failures between IM and Presence Service Service and Unified Communications Manager.

#CISCO CUCM 8.6 UPGRADE PATH MANUAL#

The IM and Presence Service Service upgrade process automatically updates these entries on the Unified Communications Manager cluster during the final stages (switch version) of the upgrade process.ДЇor upgrades from Release 8.x or 9.x to Release 10.x or later, any manual modification of these entries during the upgrade You install or upgrade Unified Communications Manager or IM and Presence Service serivce.Дo not modify any of the IM and Presence Service Service server entries on the Application Server or Server configuration pages of the Cisco Unified CM Administration interface.
