Hi, as you can see in this (and other) threads, some guys with ex-V visa were denied on entry (on visa exempt, didn't had TR I think), and then they returned with a new passport with no issues... If you intend to come back with old V visa in your passport, you should definitely make proper Tourist Visa, and also very important to check with your visa agent if they can assist if border i/o try to deny your entry (some agents offer this 'special service', on certain airports, with certain officers ???? ).
