That might be because you're not supposed to use that command for upgrades, you're supposed to use mysql_upgrade_service.exe for this. Just did this on one of my server instances and it was almost entirely pain-free. Very happy with the result.

I suggest rather reporting this as a bug where someone can try to recreate.
