This article provides a comprehensive guide for migrating enterprise Oracle databases to Amazon Aurora DSQL using AWS services.

• Amazon Aurora DSQL is a serverless, distributed SQL database with PostgreSQL compatibility and multi-Region support
• Migration uses AWS DMS to extract Oracle data to S3, AWS Glue for schema creation and data transformation
• Step Functions orchestrates the workflow, Lambda extracts table mappings, and Glue loads data into Aurora DSQL
• Solution addresses authentication complexity, schema automation, and data loading constraints specific to Aurora DSQL
• Comprehensive security implementation includes IAM least-privilege roles, encryption, VPC endpoints, and SQL injection prevention
• Complete sample code and state machine definitions available in GitHub repository
• Detailed data type mapping from Oracle/Glue types to PostgreSQL-compatible Aurora DSQL types provided

This automated migration pipeline enables enterprise-scale Oracle-to-Aurora DSQL migrations with reduced manual intervention and operational complexity.
