Upgrading Cloudera Manager 5 to the Latest Cloudera Manager, In most cases it is possible to complete the following upgrade without shutting down most CDH services, although you may need to stop some dependent services. CDH daemons can continue running, unaffected, while Cloudera Manager is upgraded. The upgrade process does not affect your CDH installation. After upgrading Cloudera Manager you may also want to upgrade CDH 5 clusters to CDH 5.4.5 or latest.

Take database backup.

If we are running a dedicated database which is recommended in production setup. then we need to take a backup of the DB as a precaution.

Assuming we are using a dedicated DB.

Stop Cloudera Manager Server, Database, and Agent

Shutdown cloudera manager server.

sudo service cloudera-scm-server stop

If cloudera manager is also running an Agent service.

sudo service cloudera-scm-agent stop

NOTE : If we are using a standalone database then we need to stop that as well.

sudo service cloudera-scm-server-db stop
