Chapter 9. Moving the Ambari Server
To transfer an Ambari Server that uses the default, embedded, PostgreSQL database from one host to a new host:
Steps
Back up current data - from the original Ambari Server database.
Update all Agents - to point to the new Ambari Server.
Install the New Ambari Server - on the new host and populate databases with information from the original Server.
If your Ambari Server is using one of the non-default databases, such as MySQL, Oracle, or an existing PostgreSQL instance, you must use backup, restore, and stop/start procedures specific to that database type.
