Description Jose Ortiz Padilla 2019-07-30 13:17:32 UTC 
Document URL: 

https://docs.openshift.com/container-platform/3.11/upgrading/downgrade.html

Section Number and Name: 

Downgrading a cluster to version 3.10 is supported for only RPM-based installations of OpenShift Container Platform, and you must take your entire cluster offline to downgrade.


Describe the issue: 
They are planning an upgrade of their platform from 3.10 to 3.11. They need a way to downgrade in case of problems. But they are using an Atomic installation instead the suported RPM. They chose atomic after a meeting with Red Hat Architects


Suggestions for improvement: 

Add a section for downgrading from 3.11 to 3.10 of Atomic Host installation
