When you default install an SQL 2012 R2 server, the database collation is “Latin1_General_CI_AS“. But if you want to install System Center Configuration Manager, one of the prerequisites is that the database collation is “SQL_Latin1_General_CP1_CI_AS“. My SQL server has only one instance, so I had to change the database collation. There are no databases configured yet, so no problem for me at all.

1.) Make sure you backup all your data!
2.) Attach the SQL 2012 R2 ISO
3.) Run the command prompt as administrator
4.) Type the following command
Setup /QUIET /ACTION=REBUILDDATABASE /INSTANCENAME=InstanceName
/SQLSYSADMINACCOUNTS=accounts /SAPWD= StrongPassword
/SQLCOLLATION=CollationName
4.) After the setup has finished, the database collation has changed. You’re now ready to rock!
