Backward Compatibility: Migration Considerations

If you are upgrading from an earlier release of SAP Sybase IQ, several new features and functionality are backward compatible.

• GRANT/REVOKE Syntax
  The syntax to grant and revoke system privileges in the role-based security model has changed significantly.
• Role-Based Security in Stored Procedures
  The enhanced role-based security model of SAP Sybase IQ 16.0 retains backward compatibility with authority-based syntax.
• Privileged System Procedure Execution
  As part of role-based security, the way in which privileged system procedures run has changed.
