Installing a cumulative update or service pack
As discussed previously, a current list of cumulative updates and service packs for Exchange Server 2013 can be found at http://technet.microsoft.com/en-us/library/jj907309(v=exchg.150).aspx.
When you are ready to run Setup and install an update, you can begin
the installation. If you are installing a new server using a current
cumulative update or service pack, follow the procedure as discussed
previously under “Installing Exchange Server.” Otherwise, to update an
existing installation of Exchange 2013, complete the following steps:
-
Log on to the server using an administrator account. When you
install the Mailbox and Client Access roles, you must use a domain
account that is a member of the Enterprise Administrators group. If
you’ve already prepared Active Directory, this account must also be a
member of the Exchange Organization Administrators group.
Important
Before beginning setup, you should ensure that the server’s Windows
PowerShell Script Execution Policy is set to unrestricted. Check the
current setting by entering Get-ExecutionPolicy at a PowerShell prompt.
Set the execution policy to unrestricted by entering
Set-ExecutionPolicy Unrestricted. If you don’t modify the execution
policy, Exchange Server may not be upgraded properly. Afterward, close
any open Windows PowerShell or MMC windows. Otherwise you will see a
warning during the readi-ness checks that you need to close these
windows. The installation process makes updates to Windows PowerShell
and MMC and requires exclusive access.
Caution
If you are applying a cumulative update or service pack to an
existing Exchange 2013 server, any customized per-server settings you
made in Exchange configuration files will be overwritten. To prevent
this, save your customized settings before you run Setup. This will
help you easily reconfigure your server after the update.
-
Access the folder where you extracted the Exchange setup files, and
then start Exchange 2013 Setup by double-tapping or double-clicking
Setup.exe. If you’ve enabled User Access Control (UAC), you must press
and hold or right-click Setup.exe and select Run As Administrator. -
On the Check For Updates page, you can specify whether to check for
updates to the setup process. If you don’t want to check for updates,
select Don’t Check For Updates before you tap or click Next to
continue. Setup will then copy files and initialize resources, as shown
in Figure 1 and Figure 2.
The server also tries to validate the state of Active Directory. If
the server is unable to validate the state of Active Directory and
choose a domain controller to work with, Setup will log errors and may
also report that a domain controller could not be located. If errors
are reported, do not continue with the installation. Instead, exit
Setup and resolve the communication problem. -
If
you are installing a new server, you’ll see the Introduction page. If
you are updating an existing server, you’ll see the Upgrade page, shown
in Figure 3. Tap or click Next to continue.
Important
Seeing the Upgrade page is a confirmation that Setup identified the
existing Exchange 2013 installation on the server. There is a problem
if you are applying an update or service pack to a server already
running Exchange 2013 and don’t see the Upgrade page at this point. You
may need to restart the server or resume Exchange services that have
been stopped and then re-run Setup.
-
On the License Agreement page, review the software license terms. If
you agree to the terms, select I Accept The Terms In The License
Agreement, and then tap or click Next. -
On the Readiness Checks page, shown in Figure 4,
ensure the prerequisite checks completed successfully. If they haven’t,
you must resolve any reported errors before you can update Exchange
Server 2013. For most errors, you don’t need to exit Setup. After
resolving a reported error, tap or click Retry to run the prerequisite
checks again.
Note
A cumulative update or service pack may require additional Windows
components. For example, Cumulative Update 1 required the Failover
Cluster Command Line Interface component be installed. This is a Remote
Server Administration Tool component that could be selected on the
feature page of the Add Roles And Features Wizard. The component was
listed under Remote Server Administration Tools, Feature Administration
Tools, Failover Clustering Tools.
-
When all readiness
checks have completed successfully, tap or click Install to update
Exchange 2013. The installation process should take about 60 minutes.
The Setup Progress page, shown in Figure 5,
tracks the progress of the installation. The installation is performed
in a series of steps, with the progress for the current step tracked
with a progress bar and as a percentage of completion. The number of
steps varies, depending on the tasks Setup must perform to prepare the
environment, as well as the options you selected.
As part of the update,
Setup removes existing Exchange files from the installation and then
copies new files into the appropriate directories. Finally, you’ll see
the Setup Completed page, shown in Figure 6, when Setup completes the installation.
You must restart the server to finalize the installation. After you
restart the server, you can verify the update using the techniques
discussed previously under “Verifying and completing the installation.”
Because any customized per-server settings in Exchange configuration
files are overwritten, you’ll need to restore the related files or
re-create the customized settings.
