To transfer an Ambari Server that uses the default, PostgreSQL database to a new host, use the following instructions:
Back up all current data - from the original Ambari Server and MapReduce databases.
Update all Agents - to point to the new Ambari Server.
Install the New Server - on a new host and populate databases with information from original Server.

If your Ambari database is one of the non-default types, such as Oracle, adjust the database backup, restore, and stop/start procedures to match that database type. |
