Initial Assessment: The client was heavily dependent on email for day-to-day operations, and their previous hosting provider was leaving, creating a hard deadline. Any downtime could disrupt critical business processes, making this a high-stakes scenario.
Strategic Thinking: I identified key risks including domain configuration errors, potential email downtime, and misalignment with operational schedules. To mitigate risk, I proposed performing a controlled test using a dummy email address to validate the changes before touching the live system.
Execution: The migration was scheduled during low-impact hours (Saturday). MX records were updated systematically, the test email was verified, and only then did I proceed with the live migration. Every step was monitored to ensure continuity and correctness.
Outcome: The email system transitioned seamlessly to the new provider with zero downtime. The client’s operations continued uninterrupted, and the process highlighted proactive risk management, meticulous technical execution, and CTO-level oversight of infrastructure-dependent projects.
