Considerations When Upgrading from Pre-16.0 Releases

Upgrading from pre-16.0 releases has additional implications, including the role-based security model replacing authorities, permissions, object-level permissions, and groups; and database file migration tasks required for upgrading 12.7 databases.

• Space Considerations
  Flat FP indexes require more storage space in 16.0 than in earlier releases due to different architecture. Please plan for increased storage space requirements.
• System Procedures Changes After Upgrading from 15.x
  The way privileged system procedures run has changed with the enhanced role-based security.
• Role-Based Security After Upgrading from 15.x
  Role-based security replaces the authority-based security model as of SAP Sybase IQ 16.0.
• SAP Sybase IQ 12.7 Database Migration
  Updating a 12.7 catalog to 16.0 SPx requires a database file migration, not a simple database upgrade. Migration tools bundled with SAP Sybase IQ 16.0 SPx can recreate the legacy database schema and database options.
