Convert DSN to UDL

QUICK ANSWER
Is it possible to convert DSN to UDL?
Yes - DSN converts to UDL.

The closest real conversion: a UDL (Universal Data Link) is the OLE DB equivalent of a File DSN. There's no automatic converter - recreate the connection: open the .dsn to read its DRIVER/SERVER/DATABASE, then build an equivalent .udl in the Data Link Properties dialog (or paste an equivalent connection string).
