I have a task to test use of DTI on our Windchill PDMLink instance/configuration. My first responsibility for that is to put together a user test plan. We are currently on version 11 of PDMLink but will be upgrading to 12.x, including the plugin, sometime in the next few months. Where can I find information on the changes/differences between DTI for version 11 and 12? Is there a "user guide" for DTI?
