Hi,

I am hoping to get some clarification around the new servicing model on Office 365 ProPlus.

Let say I have older version of O365 ProPlus such as 1701 & 1609 on some computers (Some on deferred, some on monthly channel).  Will any of the below bring them up to the latest version?  What will be the process to have these old version of ProPlus upgraded to the latest (1803 build 9126.2152)
