You are migrating a 5 TB on-premises Oracle database to Azure Database for PostgreSQL.

The business requires that the migration results in less than 15 minutes of application downtime. You plan to use the Azure Database Migration Service (DMS).

Which TWO actions must you perform to achieve this near-zero downtime migration? (Select TWO)

To achieve a near-zero downtime migration for a large database, you must use an 'Online' migration strategy with Azure Database Migration Service (DMS). In an online migration, DMS performs the initial full load of the 5 TB database while the on-premises Oracle database remains fully operational. Once the initial load is complete, DMS uses continuous synchronization (Change Data Capture) to replicate any new transactions to PostgreSQL. The 15-minute downtime only occurs during the final 'cutover', where you stop the application, allow the final few transactions to sync, and update the connection strings.
