In order to import licences from Houselogix to drivercentral all you will need to do is Create a Project on drivercentral, install the cloud driver locally, then connect the cloud driver to your project.
Once the cloud driver is added to the project it will scan for all applicable licences that it can import into your projects portal.
Please note that this process is based on the MAC address of the controller. If the controller was changed in the project the cloud driver may not recognize old houselogix licences. If this is the case please Submit a Support Ticket and be sure to include the licence number and the MAC address of the old controller.
A complete overview of importing licences has been created in a youtube that walks through the steps of importing licences and getting setup on drivercentral: DriverCentral Cloud Driver and Control4 integration
