Yes, the SQLite file is there and there is also a settings.xml file which holds the audio assignments etc.
Thanks Jason. That's the SQLite file, yeah?
The VoiceTrack data is located at C:\ProgramData\PlayIt VoiceTrack. C:\ProgramData is a hidden folder by default so that folder is best located by pressing Windows Key + R and typing C:\ProgramData\PlayIt VoiceTrack then click OK.
Copy the contents of this folder to the same location on your new computer.
