Upgrading Windchill Digital Product Traceability Extension
* 
To avoid compatibility issues, PTC strongly recommends that you check the Windchill Software Matrices on PTC.com before upgrading the Windchill Digital Product Traceability extension.
* 
PTC recommends that you back up all custom configuration Things prior to an upgrade.
Use the following instructions to upgrade and use release-specific Windchill Digital Product Traceability extension:
1. Upgrade your installed version of ThingWorx Platform and ThingWorx Flow to the required version. For instruction on performing the upgrade, see the guide Upgrading to ThingWorx on Reference Documents.
2. Download the Windchill_Digital_Product_Traceability_Bundle zip file from the PTC Software Download page on PTC.com, and extract the contents of the zip to a local drive.
3. Import the Windchill_Digital_Product_Traceability-extension to ThingWorx Platform. For information on importing extensions in ThingWorx Platform, see the topic Configuring the Windchill Digital Product Traceability (DPT) Extension in ThingWorx in the Windchill Help Center.
4. Restart ThingWorx Platform. The downloaded Windchill_Digital_Product_Traceability-extension overwrites any previous or older version after this step is performed.
5. Verify that the appropriate ThingWorx entities are available in ThingWorx Composer after the Windchill_Digital_Product_Traceability-extension is imported. For information on the list of entities displayed in ThingWorx Composer, see the topic Configuring the Windchill Digital Product Traceability (DPT) Extension in ThingWorx in the Windchill Help Center.
