After installing fresh copy of Exchange 2013 it is always good idea to sneak out and look for upgrades and patches available. As of today, Oct 8, 2013 latest update for Exchange 2013 is Cumulative Update 2 which was released in July 9, 2013. The steps to install Exchange Cumulative Update 2 in Exchange Server 2013 is fairly easy. If you have separate box for CAS and Mailbox role, then you have to follow steps shown below for both boxes. In my case, I have both roles installed in one box.

The final build number for Exchange CU2 is 15.0.712.24. To view your current build, type following command in EMS,

As you can see below the current build of my Exchange Server is 516.32

So we need to upgrade to 712.24 version. Download the CU2 install package.

Step 1: PowerShell Execution Policy

Before actually installing the update there are some pre-requisites you must perform. At first, perform full system backup of the Exchange server. The PowerShell execution policy must be set to unrestricted. To check, type Get-ExecutionPolicy cmdlet. If it is not unrestricted then type, Set-ExecutionPolicy Unrestricted cmdletYou can see it below.

Execution Policy

Step 2: Prepare AD and Domains

Before installing the update of Exchange Server you need to update Active Directory. So run this command from command prompt to update schema partition,

C:/> setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms

Schema Update

Similarly, type following command to update active directory.

C:/> setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms

Prepare AD

Step 3: Install Update

After preparing your environment, now it’s time to actually install the update. Run the Setup.exe from the extracted location in your Exchange server. At first, the installation will give you an option to check for updates. Choose the option to download updates and click Next.

1. Check for Updates

The installation will download the required updates. Then it will copy installation files to the system.

2. Copy Files

The setup will now identify that you have an existing Exchange installation so it will prompt you to upgrade. Click Install button to upgrade the Exchange server.

3. Update

Now accept the license agreement. Click Next button again.

3. Accept EULA

The setup will now check the prerequisites. If you get an error you can always see the details of the error, fix it and start all over again. This check is performed to ensure that you can actually perform the upgrade with no problems. After the readiness check is complete click Install to start the installation process.

4. Check

The setup will now begin. You can see each roles being installed. The installation process will take about half an hour.

6. Setup Prgress

After the setup is complete click Finish button and restart the server.

After rebooting the server, you can now see the latest build number in EAC or EMS.
