IBM created some documentation for this at
https://www.ibm.com/developerworks/mydeveloperworks/wikis/home?lang=en#/wiki/IBM%20i%20Technology%20Updates/page/General%20IBM%20i%20operating%20system
Infocenter updates will wait until the next Technology Refresh.
They did this at my prompting when I submitted a request for infocenter
update. Got an email from Guy Vig. :-)
