<p>Ambari upgrade should not affect your custom service in any way.</p>
<p>Depending on what version of Ambari you are on, you might have to back up your service
definition that you placed in the Ambari server resources/common-services and resource/stacks
<p>We have a script to aid config backup / restore. Although unlikely you would need
it unless using an older Ambari version in which rpm over-wrote service definition.</p>
<p>Location: /var/lib/ambari-server/resources/scripts/</p>
<p>Newer version: /var/lib/ambari-server/resources/scripts/</p>
