Moving to the cloud without the drama

Cloud migrations rarely fail on the big pieces. The database moves, the application runs. They fail on the nightly script that emailed a report, the hard-coded address in a forgotten integration, the backup nobody tested restoring.

Start with an inventory

Before moving anything, list everything the current system does: services, databases, scheduled jobs, files, certificates, integrations, and who depends on each. The inventory is boring, and it is where most of the migration's risk is removed.

Small, reversible steps

• Move one piece at a time, starting with the least critical.
• For every step, write down how to roll back, and test it.
• Run old and new side by side where you can, and compare.
• Switch traffic gradually, not all at once.

“A migration plan without a tested rollback is a hope, not a plan.”

Measure the result

Record cost, speed and reliability before the move, and again a month after. The cloud is not automatically cheaper or faster; it is more flexible. Measuring keeps the conversation honest, and points to what to tune next.
