Exchange 2010 SP 3 installations

Dear All,

    I have exchange 2010 installed with all the roles in single box with no SP. Im planning for Exchange 2013 with HA as below.

Main Site:
Two Exchange MBX and CAS  with Kemp load balancer.
Disaster Recovery Site:
Single Exchange 2013 with MBX and CAS.

so I need to install the SP 3. can I install it directly without installing any other updates or CU, or SP??
also my active directory has three active directories ( windows 2003 and two windows 2008 32 bits) so my AD is not prepared for R2. can I just install the SP3 direct and that should be fine.

PLease advise

SP3 does a AD schema update as well, so might have to prep the domain for R2 first.

Once completed, you can install SP3 and then Rollup 2

Follow this:

1) Upgrade the schema for Exchange 2010 SP3. If you have Enterprise and Schema Admin rights, setup will do it automatically, however if not, then AD team is required to perform this task.

Purpose of this Schema Update:

In Order to have the Exchange 2010 SP3 deployed across the environment, it is a prerequisite to have the Active Directory Schema to be extended for supporting Exchange 2010 SP3. During this upgrade, the Active Directory Schema will be extended to support Exchange 2010 SP3.

2) Steps for Upgrading Exchange 2010 to SP3

Software Location:
Exchange 2010 SP3:
Rollup 2:

Note: Any Interim Updates for Exchange Server 2010 must be uninstalled prior to installing this update.

1) If you have any Exchange related AV, disable it. In my case it is Forefront.

Disable the Forefront by using below command (It might ask you to stop few EXchange services)

fscutility /disable

2) Stop the OS Antivirus services and Monitoring Agent Service for Microsoft Exchange Server.

3) Verify that Backups are completed before you start the upgrade.

4) Run the SP3 and RU2 setup files using GUI, If you are getting IIS component error goto run setup /mode:upgrade /installwindowscomponents

Note: If you are getting this error "A Restart from a Previous Installation is Pending"

Open regdit and delete the HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations key and Rerun Setup.


5) Reboot the server

6) After reboot verify below logs for any error:
Event Logs
Setup Logs (C:\ExchangeSetupLogs)
Services - All Exchange related services are running.
Check IIS Settings are not changed.
Check Authentication settings from EMC for OWA/OMA/ESW. If you find any change revert back to old.

7) Enable Forefront Protection for Exchange. Command fscutility /enable (It might ask you to stop few EXchange services)

8) Start OS Antivirus and Exchange Monitoring Agent Services


Upgrade Management Tools

If you have installed management tools in any other machine make sure to upgrade those also.
Finally: - how to verify the upgrade.

Goto Powershell and type below command.

GCM exsetup |%{$_.Fileversioninfo}

Thanks ,I have exchange in physical box, what's the best way to take a full backup from it before the sp.
AmitIT ArchitectCommented:
Just take database backup and if you done any OWA customization you can backup the bin folder as well. However, I don't think you have done any owa customization. So DB backup is enough before upgrading the server to SP3.

Also note, as this is a single server you need a downtime, so do it during non prod hours.
Don't forget to backup IIS as well..
