Database Migration Assessment With YugabyteDB Voyager

YugabyteDB Voyager is an open-source migration tool that simplifies the complex task of transitioning from single-node databases like PostgreSQL or Oracle to the distributed YugabyteDB system. It generates a comprehensive assessment report that evaluates migration complexity, identifying unsupported features and syntax incompatibilities, and offering workarounds where possible. The tool calculates a 'Migration Complexity' rating, ranging from LOW to HIGH, based on these incompatibilities and their impacts. Additionally, it provides guidance on cluster sizing and sharding, offering resource estimations and optimal configurations for the YugabyteDB cluster, including node count, vCPU, and memory requirements, tailored to the database's table sizes and throughput needs. This analysis enables users to anticipate migration challenges and prepare accordingly, ensuring a smoother and more efficient transition process.
