SQL Server Configuration File and InstanceName parameter

Question

We have a configuration file at E:\SQL_Server_2016_Install\MyConfigFile.ini that looks like below:

[OPTIONS]
ACTION = "Install"
FEATURES = SQLENGINE
INSTANCENAME = MSSQLSERVER
AGTSVCACCOUNT = "MyDomain\MyAccount"
SQLSVCACCOUNT = "MyDomain\MyAccount"
QS
IACCEPTSQLSERVERLICENSETERMS

SQL Server is then installed using below batch file:
E:\SQL_Server_2016_Install\Setup.exe /ConfigurationFile=MyConfigFile.ini /InstanceName="TestSQLServer"

Question:

Will /InstanceName="TestSQLServer" parameter override what we have in the configuration file (/InstanceName = MSSQLSERVER (default instance)), and install SQL Server as a named instance TestSQLServer ?

Answer 1

Will /InstanceName="TestSQLServer" parameter override what we have in the configuration file (/InstanceName = MSSQLSERVER (default instance)), and install SQL Server as a named instance "TestSQLServer" ?

Yes, per the below excerpt from the configuration file documentation :

• The configuration file overwrites the defaults in a package

• Command-line values overwrite the values in the configuration file
