Migrating Data to CDP OnePDF version

Migration prerequisites

You need to know the prerequisites for migrating Sentry policies from CDH to CDP One.

You must meet the following general prerequisites before starting the migration process:

  • AWS is your Cloud provider. Migrating to Azure / GCP is currently not supported.
  • The source and target migration clusters must be running the following supported versions:
    • Source cluster: CDH 5.16, CDH 6.3
    • Target cluster: CDP 7.2.15 or higher
  • You can log in as the admin user to Cloudera Manager in the CDH cluster.
  • You must have SUDO or ROOT access to perform the migration process.
  • CDH clusters must have been created using Cloudera Manager. Clusters that are not managed by Cloudera Manager cannot be registered to CDP.
  • Create an external account on the CDH cluster that has non-expiring access credentials and secret key pair.
  • Your source cluster supports compatible versions of Cloudera Manager and Cloudera Runtime shown in the following table:
    Source cluster Earliest supported Cloudera Manager Earliest supported Cloudera Runtime
    CDH 5 6.3.0 5.1.0
    CDH 6 6.3.0 6.1.0
    CDH 6 7.3.1 6.3.3

Specifically note that:

  • Your CDH cluster is registered on the CDP Management Console. For more information, see Adding a CDH cluster.
  • Open communication ports between the source CDH cluster and CDP list.
  • When you create databases, you must assign valid roles for tables and grant adequate permissions as well. And the same applies to Kafka.
