Approving SQL Server and Exchange Server Updates
Applies To: Windows Server Update Services
Updating Microsoft SQL Server Instances
Your installations (instances) of Microsoft SQL Server on one computer can possibly get complex, because you can enable any of the following SQL Server scenarios:
Multiple instances of SQL server on the computer at the same time.
Multiple versions (releases) of SQL.
SQL Server instances in multiple languages on the same computer.
Typically, there is nothing extra you have to do to update these multiple instances; you just need to make sure that when you specify your synchronization options (for example, product, update classifications, and language options), you account for requirements for the versions of the SQL Server instances you have on the computer. For more information about configuring synchronization options, see Setting Up and Running Synchronizations.
Updating Microsoft SQL Server and Microsoft Exchange Servers That Are Part of a Cluster
Both Microsoft SQL Server and Microsoft Exchange Server can be installed in a clustered environment. If there is an update available for servers in a cluster that are running these programs, each server in the cluster must be updated individually. Microsoft recommends that you update passive cluster nodes individually (for example, stop the cluster service for the server while you update it) until all cluster nodes are updated.
You can have both a stand-alone instance and a cluster instance of SQL Server on the same server. If you are updating a server that is running both a stand-alone instance and a cluster instance of SQL server, both SQL Server instances will be updated if you have specified the correct synchronization options (product, update classification, and language). For more information about setting synchronization options, see Setting Up and Running Synchronizations.
