Cumulative Update 5 for Exchange Server 2013 (KB2936880)

Question

Hi,
i have installed exchange server 2013 on separate servers, I deployed the Mailbox role on the first server, and the CAS role on the second server.
I checked the edition using the exchange management shell on the mailbox server and on the CAS server:
>>>
[PS] C:\Windows\system32>Get-ExchangeServer | fl name,edition,admindisplayversion
Name                : EXMBX
Edition             : Standard
AdminDisplayVersion : Version 15.0 (Build 516.32)
Name                : EXCAS
Edition             : Standard
AdminDisplayVersion : Version 15.0 (Build 516.32)
<<<
My question is, is it possible to update this current edition to the "Cumulative update 5 for Exchange Server 2013 (KB293688) ?
if it is, in my case, on which servers should i install this update ? on the Mailbox server ? or on the CAS server ?
i appreciate you fast response,
Thanks.

Hello,
It doesn't matter which build you choose: you should first update the mailbox role and then CAS. The best option is to have same version of all your Exchange servers (e.g. CU5).
It is not necessary to install Exchange binaries on DC.
Hope it helps,
