Upgrade path from Solaris 11.2 to 11.4

Hi,

I'm on Solaris 0.5.11-0.175.2.15.0.5.1 ( T4 and T5 servers). I tryed to find versions to which I need to upgrade to get to 11.4.

In https://docs.oracle.com/cd/E53394_01/html/E54816/gmgim.html#scrolltoc, there is:

"Updating Your System From Oracle Solaris 11.2 to Oracle Solaris 11.3

Use the pkg command-line utility to update from Oracle Solaris 11.2 to Oracle Solaris 11.3. If Oracle Solaris 11.2 is installed, with or without SRUs, no special steps are required to update the system."

What does this mean? Can I go directly to 11.3 sru23 ( which is a minimal version to jump from 11.3 to 11.4 ) or should I go to some lower version ( 11.3.2.4.0 is minimal on
