We'd been avoiding this for over a year out of pure fear. It ended up being the easiest infrastructure decision we ever made.
Engineering Lead
Everyone agreed the old infrastructure was too big, too expensive, and too fragile to touch. Nobody agreed on doing anything about it — the fear of breaking something in production had frozen the decision for over a year.
So we didn't touch production at all, at first. We built the new, right-sized environment alongside the old one and ran them in parallel, quietly, with nothing customer-facing depending on it yet. The first real test wasn't a launch — it was watching the new system handle a full day of real traffic in the background while the old one kept serving customers, untouched. That's the moment the fear started to lift.
Once the parallel run proved solid, we moved one system at a time, never all at once. Each migration took less convincing than the last, because by then the team had watched three previous ones go without incident. What started as a year-long standoff ended as a routine, almost boring process by the final migration.
Running old and new in parallel removed the risk of an all-or-nothing cutover.
Proving it quietly, before anyone had to trust it publicly, built real confidence.
Each successful migration made the next one an easier decision.
Sizing for real load, not imagined scale, cut costs immediately.
The infrastructure was never really the hard part. The hardest part was convincing a cautious team that touching it wouldn't be a disaster.
The business now runs on infrastructure sized for what it actually is, at a fraction of the old cost, on a stack any engineer can maintain without specialist help. The migration everyone avoided for a year turned out to be one of the least eventful projects of that year.
