The WordPress Migration That Taught Me to Never Skip Staging

Migrated a site directly on production once, mostly because I was genuinely in a hurry and assumed it would probably go fine without the extra step of testing first. It did not go fine, as it turned out, and the mistake played out live in front of actual site visitors rather than safely hidden somewhere nobody could see.
The database had accumulated a number of hardcoded URLs scattered through old content over the years, references I hadn't properly identified and updated during the migration process itself. Half the images across the site broke almost immediately once the switch happened, visible to anyone browsing at the time, which is precisely the situation every migration guide warns you to avoid.
Spent several genuinely stressful hours afterward tracking down and manually fixing the damage, going through page by page checking for broken image links and correcting URL references I'd missed entirely during the initial rushed migration.
For the next migration, I did things completely differently. Full backup first, treated as absolutely non-negotiable regardless of time pressure. Tested the entire process on a staging copy before touching the live site in any way, which caught the exact same category of URL issues immediately and safely, with zero actual visitors ever seeing a single broken image or missing style.
I also learned, somewhat the hard way, to genuinely plan around DNS propagation taking real time to complete, rather than assuming the domain would simply switch over instantly the moment I updated a setting somewhere in a control panel.
The difference between those two migration experiences wasn't luck or unusual technical difficulty, it was simply following a proper, patient process instead of rushing through the whole thing under unnecessary time pressure.
