To perform a reduced downtime upgrade from 12c (12.1.3 or, you must first upgrade to using the standard upgrade process.

And in this part of the documentation only new binary replacement and UA schema upgrade is being performed.. the rest of the steps like the Domain Reconfiguration & UA (Component upgrade) is not being mentioned.

There is no mention of any domain level changes or post upgrade tasks.

However if you refer the main documentation Chapter 6 (Understanding an Upgrade from a Previous 12c Release):

and also this note: 2658545.1 which mentions about upgrading specifically from you have to perform full upgrade.
