Solaris 11.4 GA was
released in 08/2018. Since then Oracle published an update (SRU) each
month.
We are now at SRU27 (November 2020). This new SRU
contains a bunch of new features.
My favorite is the Zones Sheet where you can see how the Resource Usage of your zones is.

For efficient Solaris 11 upgrades on Veritas Cluster do the following
1. Disable Evacuation of the Solaris Zones
/opt/VRTSvcs/bin/hagrp
-modify myzone_sg Evacuate 0
After the Solaris 11 Upgrade and
reboot the Zones are not evacuated to the other Cluster Node.
2. Double check AutoStartList
Check and set the
AutoStartList of your Solaris Zones Service Group to make sure
the
Zones are attached to the same Node they are currently running on.
/opt/VRTSvcs/bin/hagrp -modify myzone_sg AutoStartList node1 node2
With this setup you can upgrade your first node, reboot and verify all Zones are running fine.
pkg update --be-name
s11.3.36 entire@0.5.11,5.11-0.175.3.36
init 6
If all is well with your Solaris Zones and Apps you can do
the same with your second node.
And after all your nodes are upgraded you can enable Evacuation again.
/opt/VRTSvcs/bin/hagrp -modify myzone_sg Evacuate 1
Happy Upgrading ..
