Installing Exchange 2010 SP3

Consider the following when you deploy Exchange 2010 SP3:

Exchange 2010 SP3 makes updates to the Active Directory schema. To learn more about these schema changes, see Exchange Server Changes to the Active Directory Schema.
You can select an option that installs the required Windows operating system roles and features for each selected Exchange 2010 SP3 server role.
You can install Exchange 2010 SP3 only on computers that are running Windows Server 2008 with Service Pack 2 (SP2), Windows Server 2008 R2, or Windows Server 2012.

For detailed information about the requirements and steps for installing Exchange 2010 SP3, see the following topics:

Database Schema Upgrades

The database schema for Exchange 2010 has been updated in Exchange 2010 SP1. Because SP3 contains all the fixes included in SP2 and SP1, when Exchange 2010 RTM Mailbox servers are upgraded to SP3, the databases are upgraded to the Exchange 2010 SP1 version of the database schema. This database schema upgrade process adds time to the overall service pack upgrade process. During the upgrade, the database is dismounted, and all mailboxes in that database are taken offline. If you're upgrading the Mailbox server from the release to manufacturing (RTM) version of Exchange 2010 to Exchange 2010 SP3, the database upgrade process could take an additional 30 minutes or longer per database. You can track the progress of the database upgrade process by examining event 1185 in the Application event log on the server you're upgrading. After a database has been updated to the Exchange 2010 SP3 schema, it can't be mounted on a RTM Mailbox server.

If you're upgrading from Exchange 2010 SP2 or SP1 to Exchange 2010 SP3, the upgrade process takes less time, because there is no database schema upgrade. In addition, you can safely move a database between servers running Exchange 2010 SP1, SP2 or SP3. Even though you can move databases between mailbox servers running different service pack levels, you should complete the upgrade of all DAG members to the same service pack level without too much delay. We recommend that you minimize the amount of time you have your DAG members running different service pack levels.
