Summary

This pattern provides guidance for migrating an on-premises Oracle database to Amazon Redshift using AWS Schema Conversion Tool (AWS SCT) data extraction agents. An agent is an external program that is integrated with AWS SCT but performs data transformation elsewhere and interacts with other AWS services on your behalf.              

Prerequisites and limitations

Prerequisites

  • An Oracle source database used for the data warehouse workload in an on-premises data center 

  • An active AWS account

Product versions

Architecture

Source technology stack

  • An on-premises Oracle database 

Target technology stack

  • Amazon Redshift

Data migration architecture

Tools

  • AWS SCTAWS Schema Conversion Tool (AWS SCT) handles heterogeneous database migrations by automatically converting the source database schema and a majority of the custom code to a format that's compatible with the target database. When the source and target databases are very different from one another, you can use an AWS SCT agent to perform additional data transformation. For more information, see Migrating Data from an On-Premises Data Warehouse to Amazon Redshift in the AWS documentation.
