Clone an Instance of a CUCM Device Model
-----------------------------------------

To save time, make a copy of an existing instance of a device model rather
than adding a new one. To do this, use the clone operation. When you
create a clone, give it a new unique name and modify other device model
fields as needed before saving.

.. note::

   You can clone an instance of a device model to the same Cisco Unified CM
   or to a different Cisco Unified CM.
   
   If you clone to a different Cisco Unified CM, make sure that all device
   model fields have values that are appropriate for the target Cisco Unified
   CM. For example, make sure calling search spaces specified in the source
   instance exist on the target Cisco Unified CM.


**Perform these steps**:

1. Log in as provider, reseller, or customer administrator.
2. Do one of the following:

   * If you logged in as provider or reseller administrator, choose
     **Apps Management > CUCM > {device_model_type}**.
   * If you logged in as customer administrator, choose
     **Apps Management > Advanced > {device_model_type}**.
     
3. From the device model list, click the instance to be cloned.
4. Click **Action > Clone**.
5. Depending on the device model, do one of the following:

   * When prompted, choose the NDL that contains the target Cisco Unified CM.
   * choose the target Cisco Unified CM from the **CUCM** drop-down menu.
   
6. Enter a unique name for the new instance of the device model in the **Name** field.
7. Modify other fields as required.

   For more detailed information about the fields, see the corresponding topic on
   configuring a new instance of the device model. For example, if you are cloning
   a SIP trunk, see under :ref:`how_to_configure_sip_trunks` for the SIP trunk
   field descriptions.

8. Click **Save** to save the cloned instance.

The new instance appears in the list. The new instance is created on the
target Cisco Unified CM.
