 Chapter 3. Moving the Ambari Server

Use the following instructions to transfer the Ambari Server to a new host.

[Note]Note

These steps describe moving the Ambari Server when it uses the default PostgreSQL database. If you are using a non-default database such as Oracle for Ambari, adjust the database backup, restore, and stop/start procedures to match that database.

  1. Back up all current data from the original Ambari Server and MapReduce databases.

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

  3. Install the Server on a new host and populate databases with information from original Server.
