At 05:40 on August 24, 2026, I migrated them all into my self-hosted Windmill—45/45 smoke tests green, all original schedules removed. If I&rsquo;d done this sooner, I would&rsquo;ve saved a lot of midnight log-diving. But the closer I got to actually doing it, the more I realized the migration itself had more pitfalls than cron ever did.
