Chapter 5. Moving the Ambari Server

To transfer an Ambari Server that uses the default, embedded, PostgreSQL database from one host to a new host, use the following instructions:

  1. Back up current data - from the original Ambari Server database.

  2. Update all Agents - to point to the new Ambari Server.

  3. 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) then be sure to follow backup, restore, and stop/start procedures that match that database type.
