I started an the upgrade on our Exchange 2013 Standard server last night. It was previously on CU3 and I'm updating it to SP1.
It's been 13 hours and it's still only on step 14 of 18.
Our server meets the minimum hardware requirements for Exchange 2013, although we are on the very low end for RAM (8 GB).
Do others have similar experiences? How long did it take you to install SP1?
Besides having a test environment or running high availability does anybody have tips for how to speed up this process?
EDIT: After reviewing the logs (see my first response below) I see that the Set-LocalPermissions cmdlet is taking over an hour to run each time it's called. Any idea why that would be?
