Exchange Server 2013 Service Pack 1 (SP1) is now available for download! Please make sure to read the release notesbefore installing SP1. The final build number for Exchange Server 2013 SP1 is 15.00.0847.032.
Upgrading to SP1/Deploying SP1
As with all cumulative updates (CUs), SP1 is a full build of Exchange, and the deployment of SP1 is just like the deployment of a cumulative update.
Active Directory Preparation
Prior to or concurrent with upgrading or deploying SP1 onto a server, you must update Active Directory. These are the required actions to perform prior to installing SP1 on a server.
1. Exchange 2013 SP1 includes schema changes. Therefore, you will need to execute the following command to apply the schema changes.
setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms
2. Exchange 2013 SP1 includes enterprise Active Directory changes (e.g., RBAC roles have been updated to support new cmdlets and/or properties). Therefore, you will need to execute the following command.
setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms
Once the above preparatory steps are completed, you can install SP1 on your servers. Of course, as always, if you don’t separately perform the above steps, they will be performed by Setup when you install your first Exchange 2013 SP1 server. If this is your first Exchange 2013 server deployment, you will need to deploy both Client Access Server and Mailbox Server roles in your organization.
If you already deployed Exchange 2013 RTM code and want to upgrade to SP1, you will run the following command from a command line.
setup.exe /m:upgrade /IAcceptExchangeServerLicenseTerms
Alternatively you can start the installation through the GUI installer.
