Question 910
A team needs to migrate an actively changing relational database with limited downtime. Which precaution would MOST reduce the chance of the problem returning?
Explanation
Correct Answer
Monitor replication lag and verify application compatibility separately. This continuing control fits because DMS can capture supported source changes while initial data copies complete. The associated appropriate response is: Use AWS Database Migration Service for supported ongoing replication and cutover. An observable check is: The target is reconciled with a known source change point before cutover.
