This is in the RHEL 7.6 Beta Release Notes:

Part I. New Features
This part documents new features and major enhancements introduced in 
Red Hat Enterprise Linux 7.6 Beta.

Chapter 4. General Updates
In-place upgrade from Red Hat Enterprise Linux 6 to Red Hat Enterprise 
Linux 7

An in-place upgrade offers a way of upgrading a system to a new major 
release of Red Hat Enterprise Linux by replacing the existing operating 
system. To perform an in-place upgrade, use the Preupgrade Assistant, a 
utility that checks the system for upgrade issues before running the 
actual upgrade, and that also provides additional scripts for the Red 
Hat Upgrade Tool. When you have solved all the problems reported by the 
Preupgrade Assistant, use the Red Hat Upgrade Tool to upgrade the system.
