Question How and for what is AWS SCT useful?

I am looking to migrate some databases (in Terabytes) from oracle, MS SQL and Sybase to PostgreSQL I came across - SCT as one of the tools which might be useful I have a few questions regarding the viability and ability of SCT for the task:

Questions:

1. Is AWS SCT able to migrate databases (Data and Schema both) from Oracle, MS SQL and Sybase to PostgreSQL ?
2. Is AWs SCT able to migrate Triggers, Queries, Views and Stored Procedures ?
3. Does this migration happen on-premises or I will have upload/transfer to upload my data to AWS cloud compute or S3 instances, migrate/convert and download back ?
4. What is the largest database size that can be migrated using AWS SCT (Giga/Terabytes/Records) ?
5. How fast is the database migrated (Data per Time) ?
6. What is the accuracy of the migration (Percent) ?
7. how do I use the AWS SCT tool ? ( example: Is it available for public download? Are there any Paid licenses? Does it come bundled with some other service which we have to buy? )
8. I would also appreciate if there is any extra information about AWS services which might help my project.
