It looks the Photographic Images categories now have the Item Specifics showing.
John,
We don’t have direct mapping of one Item Specific to another, but it could be copied with an Item CSV export of ItemID and Item Specifics, rename the column header to the new name and remove the other IS columns you aren’t updating. Then Import from CSV with the option to update. That should copy the old IS to the new IS.
