Redeploy Your Custom Tasks
If you have custom tasks, reimport those custom tasks you backed up earlier. To do so, complete the following steps:
1. Configure custom tasks for the new Windchill Connector:
ThingWorx Navigate 1.8 uses ptc-windchill-integration-connector. You must do one of the following to make sure your custom tasks work with the connector:
If your task uses Info*Engine tasks, reconfigure ptc-windchill-demo-thing.
* 
Windchill must be configured for SSL. For more information, see Using SSL for a Secure Connection.
If your task uses REST services, update your task to use the ptc-windchill-integration-connector thing. To do this, you must recreate the services on the connector. Only REST services are supported on the connector.
For more information, see Upgrade Your Custom Tasks.
2. Restart Apache Tomcat and ThingWorx Integration Runtime.
