A company is running its critical production workload on a 500 GB Amazon Aurora MySQL DB cluster. A database engineer must move the workload to a new Amazon Aurora Serverless MySQL DB cluster without data loss.
Which solution will accomplish the move with the LEAST downtime and the LEAST application impact?
A. Modify the existing DB cluster and update the Aurora configuration to "Serverless."
B. Create a snapshot of the existing DB cluster and restore it to a new Aurora Serverless DB cluster.
C. Create an Aurora Serverless replica from the existing DB cluster and promote it to primary when the replica lag is minimal.
D. Replicate the data between the existing DB cluster and a new Aurora Serverless DB cluster by using AWS Database Migration Service (AWS DMS) with change data capture (CDC) enabled.
