Connecting to IQ 12.6 using ODBC DSN for 12.5 [CR 376618]

You cannot connect to a Sybase IQ 12.6 server using an ODBC Data Source Name (DSN) created for a 12.5 server, even if you specify the same server name, port number, and database name.

Use the ODBC Data Source Administrator to remove DSNs created in 12.5 and add new DSNs.
