The ans is C. Defer. Main ask is: Which step can be taken to ensure that the application is not interrupted? Cloning have downtime. However, for the Aurora MySQL major version upgrade procedure with minimum database downtime, you can use database clone and in-place upgrade process (using Aurora MySQL 1.22.3 or higher version). The following diagram illustrates this updated architecture.
