For the TC to FAA conversion there is no practical test. You have TC verify your license to the FAA, get at least a third class medical, pass a short air law and communication written test, walk into a FSDO you've picked in advance and walk out with your certificate. Before you use your new certificate you still need a flight review and the level of medical required for the certificate and you have to be current (by FAA standards) in that category and class.
See AC 61-135.
