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.
