A solution architect is planning a database migration from an Oracle database to Amazon Aurora with PostgreSQL. During the planning phase, the solution architect would like to perform an assessment of migration complexity and size and identify any proprietary technology that would require database and application modifications. What service can help the solution architect develop this assessment report and provide recommendations on migration strategies and tools?

Answer options:

A.AWS DMS
B.AWS SCT
C.AWS WQF
D.AWS DataSync

Answer: C
Option A is incorrect because AWS DMS is a tool that performs data migration during a database migration process.
Option B is incorrect because AWS SCT is a tool for accessing schema conversion and converting existing database schema from one database engine to another.
Option C is CORRECT because AWS Workload Qualification Framework (AWS WQF) is a standalone tool that is used during the database migration planning phase to assess migration workloads. It produces an assessment report detailing migration complexity and size and provides migration strategy and tool recommendations.
Option D is incorrect because AWS DataSync is a data migration service for transferring data from on-premises file storage sources to AWS services such as S3 and EFS.
