The items that are newly created by copying or duplicating have the same Statistics (Created Date, Created By, Updated Date, Updated By, Revision) as their originals. The same happens with their children items that were copied or duplicated together with them.
When researched, found a blog that provides an ItemCopiedEventHandler workaround; however it was designed for an older version of Sitecore(8.0). We are currently in 9.3.
Can anyone share your thoughts on this?
