Before you begin

Consider this before you start your upgrade.

• Ensure that you know whether you want to do a major (HDP 2.6.x to HDP 3.0.1) or a minor (HDP 3.0.0 to HDP 3.0.1) upgrade.
• Ensure that you know which HDP components you need to upgrade at your installation.
• Read the Prepare to Upgrade section in the Ambari Upgrade Guide.
