CFM upgrade and migration paths

Cloudera strongly encourages you to run NiFi on Cloudera Data Platform so that you can take advantage of the latest updates and features. Review the following upgrade and migration information to ensure that you are aware of the requirements pertaining to upgrade or migration scenario.

You are using HDF today

From HDF 3.5.2, you have two options to migrate to CFM on CDP Private Cloud Base:

  • Migration

    Migration is the less disruptive option but requires that you have both a CFM cluster and the HDF cluster running at the same time. For migration instructions, review the following documentation links in the Related information section below.

    • HDF to CFM in CDP Private Cloud Base Migration

    • Use case examples on how to migrate flows from HDF to CFM with no downtime

  • In-place migration

    This option allows you to install Cloudera Manager and have it taking over the management of your services.

You are using CFM 1.x on CDH today

If you are running CFM on CDH today, your first step to migrating to CFM on CDP is to ensure that you are running CFM 1.1.0. If not, you must upgrade before performing any other operation. See the Upgrading to CFM 1.1.0 link in the Related information section below for further details.

Once you are running CFM 1.1.0, you must perform two steps to run CFM on CDP Private Cloud Base.

  1. Upgrade Cloudera Manager and CDH. Review the Upgrading CDH to CDP Private Cloud Base in the Related information section below, for more information. It explains how to first upgrade Cloudera Manager, and then upgrade the cluster.
  2. Upgrade CFM from 1.1.0 to 2.x. See Upgrading to CFM 2.0.4 from CFM 1.1.0 in the Related information section below for more information.

You are using CFM 1.x on CDH 6 today

Upgrading from CDH 6 to CDP is not available today. This option is expected to be available later this year.

You are using CFM 2.x on CDP Private Cloud Base today

If you are already using CFM on CDP Private Cloud Base and you want to upgrade to the latest version of CFM, there are specific upgrade paths that you can take. Review these paths carefully before planning for an upgrade.

  • If you are running CFM 2.0.1 on CDP 7.1.1, you first need to upgrade the CFM parcel to CFM 2.0.4 before upgrading to a more recent version of CDP. See Upgrading to CFM 2.0.4 from CFM 2.0.1 in the Related information section below for more information.

  • If you are running CFM 2.0.4 on CDP Private Cloud Base version 7.1.1 through version 7.1.5 and you want to get to CFM 2.1.0, you must first upgrade the CDP platform to be on CDP 7.1.6. See Upgrading CDP Private Cloud base to a higher version in the Related information section below for more information.

    The high level steps are:

    • Preparing the upgrade

    • Upgrading the JDK if necessary

    • Upgrading the Operating System if necessary

    • Upgrading Cloudera Manager

    • Upgrading the CDP cluster
