E.
Use AWS Database Migration Service (AWS DMS) to rewrite the SOI queries in the applications
Answers
E.
Use AWS Database Migration Service (AWS DMS) to rewrite the SOI queries in the applications
Suggested answer: B, C

Explanation:

Requirement Analysis: The goal is to migrate from Microsoft SQL Server to Amazon Aurora PostgreSQL with minimal application code changes.

Babelfish for Aurora PostgreSQL: Babelfish allows Aurora PostgreSQL to understand SQL Server queries natively, reducing the need for application code changes.

AWS Schema Conversion Tool (SCT): This tool helps in converting the database schema from SQL Server to PostgreSQL.

AWS Database Migration Service (DMS): DMS can be used to migrate data from SQL Server to Aurora PostgreSQL seamlessly.

Combined Approach: Enabling Babelfish addresses the SQL query compatibility, while SCT and DMS handle the schema and data migration.
