Yes, I have seen the document. And yes, I know it is fully integrated in 6.7U1, that's the main reason to go for it.
There is no update to the one I have.
I'm a bit puzzled as to what log file to check for the upgrade results.
But from what I can see everything looks normal. I even see update manager events such as checking for notifications.
It's just that the shortcut to Update Manager and the Update Manager tabs are missing (both in HTML5 and FLEX) so there is no way of managing the updates.
