From Ambari configurations, collect passwords of databases, keystores, and IDM services
for components that are not part of the transition. This information will help in starting the
services in Cloudera Manager after transition.
Knox SSO on Ambari and Cloudera Manager: After you upgrade your cluster with Knox SSO and proxy enabled, the post upgrade Cloudera Manager tests fail because it is going through Knox SSO. The workaround is to disable the Ambari SSO before migrating the cluster because Ambari- specific configurations are not migrated to Cloudera Manager. You must explicitly enable SSO in Cloudera Manager after migration. For more information, see Proxy Cloudera Manager through Apache Knox.
