I would like to downgrade Ambari server (from 2.7.3 to 2.6.2). This is a new installation and since Ambari was never upgraded, there are no database back up files (as referenced here: https://community.hortonworks.com/questions/175812/downgrade-procedure-from-ambari-version-2610-to-l.... Therefore, I modified the instructions as follows (omitting the old database import steps and re-running ambari-server setup). Will this work without negatively affecting the other HDP 2.6.4 components? If not, is there a procedure to downgrade Ambari in a new installation?
1. Stop the ambari-server. # ambari-server stop
2. Stop all the ambari-agents on all hosts. # ambari-agent stop
3. Download the ambari.repo of the downgraded version on all agent hosts and ambari server host.
