I'm attempting to migrate tags/categories from ACDSee to Digikam. In ACDSee I'm able to write (ACDSee's) Categories to EXIF:UserComment. I'd like to follow that up with an exiftool command to copy or move those so Digikam sees them as Tags.
To determine what Digikam needs for that to happen, I tagged an image within Digikam with two tags, then used exiftool (-k).exe to see what got written.
It shows the two tags I added for both Subject and Keywords.
However, if I run the following exiftool command in an attempt to copy those ACDSee written "Catagrories" to IPTC:Keywords
