Overbuild Overview¶
Important
It is recommended that VOSS Automate training and/or VOSS Services are engaged during the initial use of the feature to help ensure optimized processes and guidance.
Note
References to HCM-F and Shared Data Repository (SDR) are only relevant if installed.
The Overbuild feature enables Provider and Reseller Administrators to integrate an existing, deployed Unified Communications (UC) system into VOSS Automate without reprovisioning, unless required. This option is available for single-cluster dedicated deployments only. Overbuild provides tools to help the administrator manage the data synced from existing configurations in Cisco Unified Communications Manager and Cisco Unity Connection.
Although a deployed Unified CM system does not contain such VOSS Automate components as a hierarchy or a subscriber, the relationship between Unified CM components makes it possible to, for example, create a VOSS Automate subscriber at a site hierarchy during the Overbuild process. The necessary workflows, macros and brownfield move processes are available for this purpose. You will not need to access these tools directly; they are part of the Run Overbuild menu interface.
The Overbuild logic can be summarized as follows:
Phones - This is based on the device pool of the phone. It will be moved to a site based on the device pool matching one of the device pools set up under the site defaults for a site.
Dual Mode Remote Destinations - This will move the remote destination to the site of the dual mode device
Users - If the user has an associated phone then the user is moved to the same site as the phone.
If the user does not have an associated phone then the user must be manually moved to the relevant site using the Move Users menu option under either User Management or Overbuild.
It is recommended this happens prior to the Overbuild process so that all their related services are moved during overbuild; otherwise the Overbuild will need to be run again after moving the user to handle their related services.
Device Profiles - this will move the device profile to the same site as the user associated to the device profile.
Remote Destination Profiles - this logic is the same as phones - based on the device pool of the RDP. It will be moved to a site based on the device pool matching one of the device pools setup under the site defaults for a site.
Remote Destinations - this will move the RD to the same site as the associated RDP
Lines - this will move the line to the same site as the phone/device profile/RDP it is associated to.
CUC Users - this will move the voicemail user to the same site as the base user.
Webex App Users - this will move existing Webex App Users that are synced into VOSS Automate to the same site as the base user (if it finds a matching email address).
Contact Center Agents - this will move contact center agents to the same site as the base user (if it finds a matching Unified CM user ID).
The Overbuild process involves five broad steps:
Perform initial manual setup and configuration on VOSS Automate.
The business information of the existing, deployed system is identified and entered into VOSS Automate, optionally by the bulk load process. This means hierarchy information is created with customers, sites and site codes. Some configuration data is initially generated, for example Site Defaults data. This data should be modified if required according to Unified CM data, so that Overbuild processing can move data to required sites.
For example, the default, generated VOSS Automate Site Defaults for a site have the Site name as the Device Pool name. Since the Site Defaults are used in the Overbuild process, this name should be modified to match the Device Pool name on the imported Phones before the Overbuild process is run. VOSS Automate allows Provider and Reseller Administrators to modify Site Defaults in order to modify the configuration of an Overbuild process.
Note:
While Customers and Sites have access to the Site Defaults under the Site Management menu, the Overbuild Defaults tab is only visible to Provider and Reseller Administrators.
Network device connections are identified, created, associated with a Network Device List, and imported. This includes Unified CM and CUCX clusters.
Caution:
Whenever this data is synced in, it becomes managed by VOSS Automate and, as a result, would be deleted by any hierarchy delete. See Delete Issues and Purges for information on managing these issues.
One Unified CM typically belongs to a customer and resides in a cluster, so this device import takes place at the created customer hierarchy. The device can also be associated with a Network Device List on VOSS Automate that is mapped to a created hierarchy.
If the Users check box is selected on the Run Overbuild tool, users exposed under the User Management menu are moved to the site of their associated phones as specified in the Site Defaults Doc Device Pools.
Users without phones will not be moved and can be moved separately - see Move Users.
The following model instances are moved from customer level to the site level:
data/Userdata/HCSHcmfUserDATdevice/cucm/Userdevice/hcmf/User(only if HCM-F is installed)
If the Lines check box is selected on the Run Overbuild tool, lines are moved to the relevant site, and marked as in use in the Directory Number (DN) inventory. If a matching DN inventory entry does not exist then one is created. DN entries are created at site by default unless the Create Internal Number Inventory at Customer check box is selected on the Site Defaults Doc Overbuild Defaults tab.
The Run Overbuild tool selects which data to move based on device pool configurations. You can run the tool for all sites, or a particular site.
Note:
The existing system’s provisioned phones that have been imported should have their Device Pools matched with Site Default Data values on each specific site.
The imported elements are moved according to Overbuild Move Workflows, which are triggered by the Run Overbuild tool. These workflows identify imported network device data and move it to the site hierarchy that corresponds to the existing deployed site.
Manually validate and modify the overbuild run by reviewing the moved items using Overview Tool. Use Device Models and/or Relations to move, update, delete, and in a few limited cases add instances of device types for the selected hierarchy.
Perform post-move operations:
Perform Self Care authentication provisioning steps for non-LDAP, LDAP, and SSO-enabled scenarios - see User Authentication.
