Overview
A Fortune 500 manufacturing company needed to modernize their aging on-premises data center infrastructure by migrating to Microsoft Azure. With over 1,000 virtual machines, legacy applications spanning 20+ years, and global manufacturing operations requiring 24/7 uptime, the migration required meticulous planning and execution.
