Overbuild Steps (provider deployment)
---------------------------------------

.. important::

   System Integrator Support Recommended - For all Managed Services: Day 2 Overbuild
   Projects, we recommend support from a System Integrator.

Provider and Reseller Administrators can follow these general steps to use
the Overbuild tool:

1. Provision the business hierarchy. This can be done manually in VOSS Automate or
   by bulk load (see "Bulk Administration" topics and :ref:`perform_a_bulk_load`).
#. Associate a shell schema group with the customer, then add a custom dial plan
   under "Advanced Configuration". (This step is optional at the site hierarchy).
   See "Provider HCS Dial Plan Management Support Guide".
#. Provision Cisco UC Applications, network device lists, and network device list
   references. Once UC Applications are configured, the sync from Cisco Unified
   Communications Manager will be scheduled and executed. See "Data Sync" topics.
#. Choose the device pool and devices for the site on both the
   **Site Defaults > General** and **Overbuild Defaults** tabs. See :ref:`overbuild_site_defaults`.
#. Choose **Run Overbuild** to move the imported UC Applications data into the site
   hierarchy that corresponds with the existing deployed site. See :ref:`run_overbuild`.

   * Users exposed under the **User Management** menu are moved to their associated
     phones if the **Users** check box is selected on the **Run Overbuild** tool.
   
     Users are moved to their phones if the phones have the user set as the OwnerUserID,
     if the **Users** check box is selected on the **Run Overbuild** tool.

     Note: The User's role is not changed when moving to Site.

   * Lines are moved and marked as in use in the Directory Number (DN) inventory
     if the **Lines** check box is selected on the **Run Overbuild** tool. A Site
     DN inventory is created.

     If the DN instance already exists, it is updated as in use. The DN inventory instance
     is created at the site level by default. This can be set to Customer in the SiteDefaultDoc
     before running OverBuild. 

     Note: Adding Directory Number inventory at Customer level is only possible if the DialPlan
     in use is non SLC(Site Location) Based, or if no DialPlan is in use.

#. Choose **Overview Tool** to verify the number of Unified Communications elements
   at the selected hierarchy and below. See :ref:`overview_tool`.
#. Optionally, review the device model types listed with hierarchy in the
   Device Models or Subscriber Management menu. See :ref:`device_models`.
#. Perform postmove operations:

   * Add your E.164 inventory (optional) - see :ref:`add_e164_inventory`.
   * Filter calling search spaces and assign a class of service (optional) -
     see :ref:`filter_css_and_assign_css`.
