This article provides a comprehensive guide for migrating a self-managed MySQL database to Amazon Aurora MySQL using AWS Database Migration Service (DMS) homogeneous data migrations. The key steps and highlights include:

• Detailed preparation of source and target database environments
• Creating necessary IAM roles, security groups, and network configurations
• Configuring AWS DMS instance profiles, data providers, and migration projects
• Implementing SSL certificates and database user permissions
• Storing database credentials securely in AWS Secrets Manager

Key technical considerations for the migration:

• Uses full load and change data capture (CDC) migration type
• Supports in-transit encryption and SSL connections
• Allows migration of database objects like functions and triggers
• Provides monitoring through CloudWatch metrics

The article emphasizes careful planning, testing, and monitoring during the migration process, recommending a cutover during low-traffic windows and verifying replication lag before switching applications.
