Hello, Community !
We're using manually installed CDH (installed from RPM, configured manually) without Cloudera Manager.
So where can I find definite guide to upgrade my environment without CM ?
I checked general documentation and didn't find this section ( https://docs.cloudera.com/documentation/enterprise/upgrade/topics/ug_cm_wizard_actions.html#concept_... )
the upgrade consists of two steps
The steps to manually upgrade CDH are listed in Upgrading CDH Manually after an Upgrade Failure
Just in case the ask is about how to upgrade a non-CM managed cluster to 6.x, be aware that this option is not available anymore in C6, see Removed Items
My browser did not show your original question, which confirms the ask is about non-CM managed cluster upgrade. Please note this option has been removed, C6 requires Cloudera Manager installation.
