Hi,
The warning which you have faced because in the Denodo Platform version 8.0, the ITP datasource and the Filter sequences are removed from the Denodo Scheduler 8.0.For more information, you could refer to the section [Features Removed from Scheduler 8.0 GA](https://community.denodo.com/docs/html/browse/8.0/en/platform/upgrade/backward_compatibility/changes_in_the_denodo_platform_8.0/features_removed_from_scheduler#features-removed-from-scheduler-8-0-ga) from the Denodo Platform Upgrade Guide.
