In the DB2 Post-installation Migration Tasks chapter of the DB2 Quick Beginnings manuals, under Optional Post-Migration Tasks, it is stated that you must use the db2uiddl command to migrate unique indexes from DB2 version 5.x and DB2 version 6. This is incorrect. Migration of unique indexes using the db2uiddl command is only required if you are migrating from a version of DB2 that is pre-version 5.
