Installing a named Instance of SQL Server 2012, on a server where it already had SQL Server 2008 R2 Instance.

Hi Expertts,

I got a requirement to install a new SQL Server 2012 on a server where it already had SQL Server 2008 R2 installed.

My question is:

what care i have to take before and after installing the new instance.

The first instance is installed on C:

can i install the second instance on the same drive leaving the default location as it is?

I am worried because of the following documentation

http://msdn.microsoft.com/en-us/library/ms143694.aspx

SQL Server Sysprep does not support side by side installation of prepared instances of SQL Server 2012 with earlier versions of SQL Server on the same computer. For example, you cannot prepare a SQL Server 2008 R2 instance side by side with a prepared instance of SQL Server 2012. However, you can install multiple prepared instances of the same major version of SQL Server side by side on the same computer. For more information, seeConsiderations for Installing SQL Server Using SysPrep.

SQL Server 2012 cannot be installed side-by-side with earlier versions of SQL Server on a computer that is running Windows Server 2008 R2 Server Core SP1. For more information on Server Core installations, seeInstall SQL Server 2012 on Server Core.

Thanks,
