Paul, you mention upgrading the Mailbox before the CAS. This is different
from earlier versions of Exchange where you start at the CAS, then Hub, etc
and mailbox last. Is there any official documentation on the server role

If you run the upgrade on a multi-role server, you will see that Setup
always upgrades the Mailbox role before the CAS role.



Hope this helps,

Question for the group.


I have a customer that is going to be installing Exchange 2013 CU13 soon.
We're getting together documents and creating checksheets for the update.


The customer insists that CU's get installed from "the outside in", meaning
from the Edge Server towards the mailbox server.


My memory says that you installed SP's and CU's in a different order:  CAS,


I can't find documentation that points to one, or the other, or really any
order at all. So I'm asking the people who have a bit more experience with


What say you?
