@HopelessNightOwl If I'm understanding you correctly, Are you saying that you want the existing horrorstories.miraheze.org wiki to be deleted, then move creepypasta.miraheze.org to horrorstories.miraheze.org? In this scenario, creepypastawiki would become horrorstorieswiki, and creepypasta.miraheze.org would be no longer exist and become available. This would be much easier and simpler than generating dumps, deleting, and recreating wikis, if possible.
