I think what you're describing is issue #2685: (Move + Merge
=> lose modifications)

I don't know the details, but came across this issue when looking for
something else. You may be able to find some more explanations in the
issue comments.

Also, I'm not sure if mergeinfo will be a problem. Maybe you should
just try it with a test repository.
