Question 1

You are designing the migration of a mission-critical 5 TB Oracle database to Azure Database for PostgreSQL.

The business requires that the database migration results in near-zero downtime for the application. The application will be pointed to the new Azure database during a brief 15-minute maintenance window.

Which migration strategy and tool should you recommend?
