Case study
The challenge
Meridian ran twelve physical servers well past their warranty. A hardware failure would have taken out billing for days, and nobody was confident the backups restored.
What we did
Audited every service and sized instances to real usage
Rehearsed the full migration on copied data twice
Cut over service by service across one weekend
Set up monitoring, alerting and automated backups with tested restores
The result
Zero downtime during the cutover
Hosting spend down 38% after right-sizing
Restores now tested automatically every week
"We slept through the migration weekend. That was the goal." — Meridian IT manager
