Nobody talks about what actually happens when a 30TB file server moves to the cloud at 2am. Everyone talks about the tools. Everyone has a plan. The cutover window opens and that’s where the real story starts.

This wasn’t a lift-and-shift. At that scale, every sequencing decision carries real consequences.

Before a single byte moved, we ran a full pre-migration assessment. The runbook that came out of it was built around one thing: keeping the business running if something went wrong at 2am. It did.

Azure Migrate was the primary tool. What made the difference wasn’t the platform — it was the configuration decisions and the sequence we ran them in.

Hyper Care ran post-cutover specifically to catch latent issues before users hit them. Not after the first ticket. Before.

Zero data loss. Minimal disruption. Stakeholders who didn’t need to be managed because they already had confidence in the plan.

The tool moves the data. The runbook, the sequencing, and the Hyper Care window protect the business that depends on it.
