Why the MSSQL class has been deprecated?

I don’t know but I don’t think that the ODBC Database class can be used in place of the MSSQLDatabase in a completely transparent way. Has anyone done any tests on code already written and running?

It is Microsoft’s recommended method for connecting to MSSQL now. The old client library is long deprecated.

You may need to change the connection strings but others have had no problems in swapping to the ODBC driver.
