Description Limitation Enterprise Groups is supported for releases 11.0(1) and higher. If the synced group includes group members from a 10.x intercluster peer, users on the higher cluster cannot view the presence of synced members from the 10.x cluster. This is due to database updates that were introduced in 11.0(1) for the Enterprise Groups sync. These updates are not a part of the 10.x releases. To guarantee that users homed on the higher cluster can view the presence of group members homed on the 10.x cluster, users on the higher cluster should manually add the 10.x users to their contact lists. There are no presence issues for manually added users. Intercluster peering with a 10.x cluster Multilevel grouping is not allowed for the group sync. Multilevel grouping When a user group and users are present in the same search base, group-only synchronization is not allowed. Instead, the user group as well as the users are synchronized. Group-only synchronization You can synchronize a maximum of 15000 user groups from Microsoft Active Directory server to the Unified Communications Manager database. Each user group can contain from 1 to 200 users. You can configure the exact amount on the Cisco Unified CM IM and Presence Administration > System > Service Parameters window. The maximum number of user accounts in the database cannot exceed 160,000. Maximum number of user groups If a user group is moved from one organization unit to another, you must perform a full sync on the original unit followed by a full sync on the new unit. User group migration Local groups are not supported. Only groups synchronized from Microsoft Active Directory are supported. Local groups Group members that are not assigned to IM and Presence Service nodes display in the contact list with the presence bubble greyed out. However, these members are considered when calculating a maximum numbers of users allowed in the contact list. Group members not assigned to IM and Presence Service nodes During migration from Microsoft Office Communication Server, the Enterprise Groups feature is not supported until users are fully migrated to the IM and Presence Service node. Migration from Microsoft Office Communication Server If you change the synchronization option in the LDAP Directory Configuration window while the synchronization is in progress, the existing synchronization remains unaffected. For example, if you change the synchronization option from Users and Groups to Users Only when the synchronization is in progress, the users and groups synchronization still continues.
