Migration Issues

SAP Sybase IQ no longer supports some legacy features. Run iqunload in schema unload mode to generate a script (reload.sql) that contains the entire database schema. Compare the contents of this file to find unsupported syntax and metadata.

• Unsupported Objects
  Check the schema for objects SAP Sybase IQ no longer supports.
• Syntax Changes
  Review the reload script (reload.sql) for legacy syntax that can cause iqunload to fail.
• Schema Size
  Increase the cache memory to migrate large and extremely large schemas.
• Output Logs
  Check the output logs to isolate migration problems.
• Data Storage Changes
  SAP Sybase IQ 16.0 migration creates a new catalog store and changes some legacy options.
• Post-Migration Files
  iqunload generates a set of files derived from the legacy database. .
