Workflow: Overview
------------------

The major change in the configuration between Cisco Unified Communications
Domain Manager from 8.x and VOSS-4-UC is the location of the master data.

In CUCDM 8.x deployments, the master copy of all data was stored in the Shared Data
Repository (SDR). Therefore any changes to the data were made in Cisco
Unified Communications Domain Manager and then synchronized down to the UC
Applications such as Cisco Unified Communications Manager.

In VOSS-4-UC, the source of master data is distributed between VOSS-4-UC and the call
manager. A bidirectional sync is used to export and import data from VOSS-4-UC
and the applications. This approach enables configuration changes to be made on
either the VOSS-4-UC or the UC applications - giving greater flexibility and
faster problem resolution.

The following chapters include content on provisioning VOSS-4-UC.
Information on the provisioning steps and interactions between VOSS-4-UC and the
various UC applications supported by Cisco HCS is included.

Details on User and Subscriber management, including LDAP-related move and push
operations, are also available.
