Staged cloud migration without stopping daily service
Solution example: moving applications and databases off on-premise servers in stages, with the shortest possible cutover window.
This is a solution example, not a record of a client project.
Servers past their support window no longer receive security updates. What usually holds the move back is not technology but a reasonable concern: the service is used throughout the working day.
What we propose is a staged move: replication runs first, the cutover is rehearsed in a mirror environment until it runs smoothly, and the rollback plan is written before the day itself. The downtime window is planned outside peak hours and announced in advance.
