Hello,
I'm starting a large scale upgrade of Exchange 2007 SP2 to Exchange 2013.
So I first need to upgrade to Exchange 2007 SP3 and CU 11.
Can I slipstream the CU11 with the install of SP3? If possible how do I do this?
If not, can I install SP3, reboot, install CU11 on the internet-facing CAS servers, moving with SP3+CU11 to the downlevel CAS servers, then to HUB and MBX. OR do I need to upgrade all exchange servers to SP3 before upgrading to CU11?
Thnx for your answer!
Regards
Frederik
