If you are careful you can use --force and pacman will ignore every
existing file and overwrite it. In this case it sounds like this is
justified, but please do NOT use it when you are not absolutely sure
about what you are doing. If --force breaks something it's totally your
fault.

Sorry I'm stressing this so much, but lots of people seem to think using
it is safe or supported, but it's not.

Before you do this, please check if there are any conflicts outside of
those 2 directories (filter pacman output with `grep -v -e ": /opt/" -e
": /var/"`) and also create a backup of them (/opt and /var) in case you
overwrite something you shouldn't.

You should also reinstall every installed package just in case something
hasn't received an update yet. `(pacman -Qq; pacman -Qqm) | sort | uniq
-u` should give you a list of all install package without AUR ones.
