Is "manual"rolling upgrade possible, ie with no Ambari? Also when will the Rolling upgrade doc be available on docs.hortonworks.com?

Yes its possible, however can take a long time.

Checkout https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsRollingUpgrade.html

We also have some documentation for 2.2.8 (http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.2.8/bk_rolling-upgrade/content/ch_overview-rolli...)

No documentation for HDP 2.3 available so far
