Delete Issues and Purges (provider deployment)
------------------------------------------------

Whenever Unified CM and CUCX data is synced into VOSS Automate, it assumes management
of the data and, as a result, that data would be deleted by any hierarchy delete
performed in VOSS Automate. These deletes can fail if your Cisco Unified Communications
Manager model dependencies don't reflect the additional data contained in existing,
provisioned dial plans brought into VOSS Automate.

There are two ways to prevent these delete failures from happening:

* Work with a Cisco System Integrator to update your HcsCucmWrapperCascadeDelPWF
  workflow to handle the dependencies in your existing dial plan.
* Perform a purge operation instead of a delete.

Purging deletes all users, subscribers, phone, profiles, and devices from a
brownfield customer's VOSS Automate while leaving these objects on the Unified CM
and the Cisco Unity Connection.

To execute a purge:

1. Log in to VOSS Automate as a reseller administrator or higher.
2. Access the **Data Sync** form (default menu **Administration Tools > Data Sync**).
3. From the hierarchy drop-downs, select the customer whose data you need to
   purge. If the data was created at the Site hierarchy, the purge only takes
   place at site level.
4. Click **HcsPurge-<IP address + fully qualified domain name + hostname>**.
5. From the **Sync Type** drop-down, choose **Purge Local Resources**. All other
   default values remain unchanged.
6. Click **Execute**.
7. Repeat steps 4-6 for the Unified CM.
8. Verify that the instances and device models are deleted by checking Phones,
   Users, and Voicemail.
   
   At this point, you can try again to migrate the customer into the Cisco Hosted
   Collaboration Solution by executing HcsPull from the same menu for Unified CM
   and Unity Connection, and then performing the Overbuild
   operations.
