About the fifth post down I posted step by step how to remove all the
outdated tags, if you are writing to the image rather than to an XMP
sidecar. The steps are not intuitively obvious, it's really easy to
miss a step, and sometimes a few outdated tags are still left behind,
necessitating a redo to get the remaining tags. But it can be done.

I moved/broke up a very large tag tree, with tags applied to around
3500 images, leaving behind duplicate, outdated tags in the images.
That was just last week using digiKam 2.9. So I experimented and
searched the internet and came up with a process that worked for me.
As a precaution, probably best to test the process on some throwaway
tags/images before deploying over important images.

Also see this post: http://duq.ca/duqamuq/?p=270. It's for an older
version of digiKam, but the process outlined looks similar.
