CDH cluster upgrade requirements for Replication Manager

Reviewing the CDH cluster upgrade guidelines and requirements for Replication Manager help you to upgrade successfully. Before you start the upgrade, check the version numbers to ensure that the clusters are in sync.

  • Ensure that the supported source and target clusters and the corresponding Cloudera Manager versions are in sync with respect to the cluster configurations prior to starting the upgrade.
  • Upgrade your target cluster to Cloudera Private Cloud Base first. Upgrading the target CDH cluster first ensures that your data on the source cluster is not corrupted or rendered invalid.
  • Upgrade the source cluster to Cloudera Private Cloud Base after the data is transitioned to the Cloudera Private Cloud Base cluster (target). And, later verify that both source and target clusters are upgraded to Cloudera Private Cloud Base clusters.
