Introduction of Traditional Databases to YugabyteDB

Migrating from traditional databases (like MySQL, PostgreSQL, or Oracle) to YugabyteDB can unlock the benefits of distributed SQL while maintaining the familiarity of relational database management systems (RDBMS). YugabyteDB offers scalability, high availability, and cloud-native features, making it ideal for modern, large-scale applications. This guide covers the migration process, from understanding the architectural differences to performing the actual migration and ensuring smooth application performance post-migration.

Prerequisites

• Understanding of traditional relational databases (MySQL, PostgreSQL, Oracle).
• Basic knowledge of YugabyteDB architecture and key features.
• Access to a test environment with both the traditional database and YugabyteDB setup.
• Knowledge of database migration strategies, tools, and techniques.
• Experience with cloud infrastructure or containerized environments (optional but beneficial).
