There are a few resources that can help you

Move ambari to new host1

Move ambari to new host2

Points to remember you should also have the same version of /etc/yum.repos.d/* contents on all the servers ,reconfigure passwordless ssh in case you will want to add a new data

Moving ambari server involves basically following steps:

1). Stop the old ambari host and then install ambari server to new host.

2). Make the "/etc/ambari-agent/conf/ambari-agent.ini" file change on all the agent hosts to point to new ambari server hostname.

3). Run the ambari-server setup command and then point to the Database instance where your amabri DB is present in the "Advance Database configuration Section". (If using postgres then choose option4 Postgres DB , not the Embedded Postgres DB).

OR if you want to move the ambari DB as well to a new host then import the DB dump backup to your new DB host and then during the ambari-server setup command choose new host details.

4). Restart Ambari server and all the ambari agents.
