About this task
Historian allows you to delete and permanently delete tags. When a tag is deleted, it is removed from the tag database, but all data for that tag is retained in the archive and the tag name cannot be re-used. When a tag is permanently deleted, all the data for that tag is removed from the archive and the tag name is available for reuse. For more information, see Deleting Tags.CAUTION: When a tag is permanently deleted, you can no longer query the data for that tag, since the data was removed from the archive.
