FM3 Changing From Topspeed to SQL(ODBC) does not copy/convert existing files

May I know atleast a bit of info on how that works? I have created a converter where i have a function and only pass the file as parameter and manually deep assign columns of old tps file to new sql file. But that’s only usable to one dictionary that I need to convert to. Procedure Passing Two File and Record Parameters for deep assign.
