Cloudera Migration Assistant Overview

The Cloudera Migration Assistant (CMA) for CDP Public Cloud is a tool for migrating both data, metadata and certain workloads from Cloudera Distribution including Apache Hadoop (CDH) to CDP Public Cloud.

Because migrating data to S3 can take a long time, you can perform multiple migrations between a source and target cluster to move the data in stages. You can also choose to migrate only part of your data as opposed to all of it. A single CMA server is designed to handle multiple migrations.
