Migrate your Sybase databases to a test Microsoft database and fully test your applications and administrative procedures against the test Microsoft database, including stress testing, before you transfer the entire production system to Microsoft SQL Server.
Review your T-SQL statements and the names of SQL Server objects for keyword conflicts before transferring your objects and data to Microsoft SQL Server.
The following table lists Sybase System 11 keywords that will not function in Microsoft SQL Server and keywords that are reserved by Microsoft SQL Server. If your T-SQL statements use any of the listed keywords, replace them with other words before you migrate your Sybase database to Microsoft SQL Server.
