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.
