I think there is some functionality missing regarding face tag management. Is it possible to change the name of a face tag in a picture (or selection of pictures) and assign it to another existing person? Is it possible to combine two persons and their tags? If the name of a face tag (in the People list) is renamed in the right click -> properties section, are these changes written to the pictures' metadata? If you remove a Person, are the face rectangles in the pictures deleted or emptied?
For merging tags we have a bug report (Bug 331864). If the name is changed from a tag, it will not be updated the image metadata yet. Again, we have a bug report (Bug 386224). However, this can be a time-consuming story. Either via the maintenance tool or select the tag in the left sidebar, select all the images and call "Write metadata to images" from the menu. Maik
I posted the picture in another bug thread, but it's also relevant here: https://imgur.com/a/vvPPV If you look carefully can see there are 3 duplicated entries (well, 6 tags which should be just 3) that should be fused. But since digikam treats tags and face regions in a similar way, it's impossible to know which are which, so the results of renaming them are a bit unpredictable at the moment. I could use another software to do that and then update Digikam's database, but I can't do that because of bug #380876, where digikam does not delete old unused tags from the database. In picasa, for instance, there's always the option to select a few faces, right click on them and "Move to the person's album -> <select the person in a list>" and those faces will be correctly renamed and saved in the picture's metadata. This simple option (I don't know if it would be easy to implement) would solve this issue once for all.

Hi. Thanks for working on this issue. However, I suppose that this bug report has been closed because now the metadata and the database are sync'd when a tag is deleted. I accidentally reported several issues in this bug, some of them are still valid. Mainly the ability to merge two face tags. Should I open a new bug just for the merging issue?
Merging tags is now also possible. It does not matter if it's a face tag. Just Drag & Drop the double tag into the path of the other. Maik
Of course, both tags must have the same name and not be in the same path, otherwise a tag must be renamed. If there are spelling errors in the tags. Maik
Oh, great then, thanks!. Btw, what would happen in the case two face tags are under the same hierarchy but with different names. e.g. "People/Michael Jackson" and "People/Michael Jakson"? Would it be possible to rename the latter to the first just by drag and drop?
