Upgrading Cloudera Manager 3.7.x

  Warning: Cloudera Manager 3 and CDH 3 have reached End of Maintenance (EOM) as of June 20, 2013. Cloudera does not support or provide patches for Cloudera Manager 3 and CDH 3 releases.

You cannot upgrade directly from Cloudera Manager 3.7.x to Cloudera Manager 5; you must upgrade to Cloudera Manager 4 first before upgrading to Cloudera Manager 5. Follow the instructions for upgrading Cloudera Manager 3.7.x to Cloudera Manager 4 in Upgrade Cloudera Manager 3.7.x to the Latest Cloudera Manager.

Note that the last step in the Cloudera Manager upgrade process is an optional step to upgrade CDH. If you are running CDH 3, this step is not optional. Cloudera Manager 5 does not support CDH 3 and will not allow you to complete the upgrade if it detects a CDH 3 cluster. You must upgrade to CDH 4 before you can upgrade to Cloudera Manager 5. Follow the steps at Upgrading CDH 3 to CDH 4 in a Cloudera Manager Deployment before you attempt to upgrade your Cloudera Manager Server to version 5.
