We have a named instance of SQL Server 2008 R2 which was installed to support a single application. The instance is on a server that also has a default instance hosting databases for several other applications.
The application using the named instance (named for the application) is no longer used. Is it safe to uninstall the named instance without risk of damaging the default instance, or are we better just off opening SQL Configuration Manager and setting the Startup Mode of the named instance to "Disabled?"
