AWS Schema Conversion Tool (AWS SCT)

The AWS Schema Conversion Tool (AWS SCT) is a critical component in the migration and transfer process when moving databases to AWS. It is important because it simplifies the process of converting database schemas from various source databases to the target AWS database, such as Amazon RDS or Amazon Aurora.

What is AWS Schema Conversion Tool?
AWS SCT is a tool that automatically converts the source database schema and a majority of the custom code, including views, stored procedures, and functions, to a format compatible with the target AWS database. It supports various source databases, including Oracle, Microsoft SQL Server, and PostgreSQL, and can convert them to Amazon RDS for MySQL, Amazon RDS for PostgreSQL, Amazon Aurora MySQL, and Amazon Aurora PostgreSQL.

How does AWS SCT work?
The process of using AWS SCT involves the following steps:
1. Install and configure AWS SCT on your local machine.
2. Connect AWS SCT to your source database and target AWS database.
3. Select the schema objects you want to convert, such as tables, views, and stored procedures.
4. AWS SCT automatically converts the schema and custom code to the target AWS database format.
5. Review and refine the converted schema and code, if necessary.
6. Apply the converted schema to your target AWS database.
