If it is impossible, please confirm if the following process is correct.
I hope to downgrade only CM 5.11.1 to CM 5.11.0
1. yum remove CM 5.11.0
2. yum install CM 5.8.5(because metadata backup vesion is 5.8.3)
3. Restore the following Cloudera Manager databases: Cloudera Manager Server Activity Monitor (depending on your deployment, this role may not be installed) Reports Manager Service Monitor Host Monitor Navigator Audit Server Navigator Metadata Server
I am worried that CM will not start because the cdh version stored in the scm metastore
does not match the actual installed version of CDH.
