When upgrading to NTA 4 and later versions, Orion makes use of the FlowStorage Database and will not add new Netflow data in the Orion database. If you chose to retain the previous data during migration, this article will describe how to remove it after the migration.
NTA 4 and later versions
When the Netflow service sees that the setting changed in the database, it will trigger the removal of the stale information from the Orion database. This will cause no changes on the FlowStorage Database.
