Update ODBC driver for existing DSN

Hello everyone,

I have a middle-tier server which has quite a lot of ODBC-DSN entires,

connecting to all our R&D databases. My problem is that the ODBC

Administrator does not provide an option to change/update the actual ODBC

driver for a connection.

After upgrading, e.g. Oracle 9 to 10 i need to change all existing DSN

setting to use the 10g Driver. How do i do this without removing all and

re-entering? I tried changing it through the registry, but apperently this

doesn't work as well as i thought.

Thanks
