Data Migrator for Hadoop to Oracle Lakehouse Migrations

This white paper discusses the Cirata Data Migrator, which facilitates the migration of data from Hadoop environments to Oracle Lakehouse. It outlines the challenges associated with Hadoop data migration, such as the volume of data and the need for minimal disruption during the process. The document details typical steps involved in the migration process, including discovery, planning, data migration, workload migration, and new analytics development. It emphasizes the importance of a migration strategy that minimizes business risks and ensures successful transitions to the Oracle Lakehouse architecture. The paper also presents a data-first approach to migrations, which allows organizations to prioritize data movement while maintaining existing production workloads. Additionally, it describes how Cirata Data Migrator automates the migration process, enabling continuous data migration without requiring system downtime. The paper concludes with a reference architecture for implementing the data migrator effectively within Oracle Cloud Infrastructure.
