Database Migration Mode

Running iqunload in database migration mode starts your legacy database, then uses the Sybase IQ 15 server to re-create the catalog store.

iqunload executes out these migration tasks:

  1. Starts the Sybase IQ 12.7/12.6 database with the unload database engine.

  2. Performs various internal database checks.

  3. Determines if the database is a multiplex write server, in which case some extra steps are taken to migrate the writer to an IQ 15.4 coordinator.

  4. Generates the schema (similar to schema unload mode).

  5. Starts the Sybase IQ 15.4 server.

  6. Creates a new database.

  7. Applies the generated schema.

  8. Executes various internal database checks to validate the metadata for migrated objects.

  9. Backs up the operating system files. This backup does not use the SQL backup command.
