Preparing Ozone for upgrade

The Ozone upgrade procedure has three steps: first, prepare Ozone for the upgrade, backup OM and SCM metadata, and lastly, upgrade CDP parcels.

Ozone will be brought to a read-only state before the upgrade so the OMs can synchronise before the upgrade.
  1. Log in to Cloudera Manager UI
