Hi Bret,
We have no issues with old setup ASE 12.5.4 Server and Sybase System 11 ODBC Client. Currently, we are just transferring our application from Windows 2003 Server to Windows Server 2008 Server R2 64bit. Our previous ODBC Driver installer (Sybase System 11) is not working anymore with 64bit OS, so we opted in using ASE ODBC Client Driver with the same version with our Server ASE.
Can we use the latest Client ASE ODBC Driver with our 12.5.4 Server ASE? Thanks.
