Greetings,<br />
<br />
I have a default installation of SQL Server 2008 installed on a windows 2008 server. I would like to install SQL Server 2005 named instance and SQL Server 2012 named instance on this server as well. Can I do so or will I have to uninstall the default installation of SQL Server 2008? I need all 3 versions to establish a test environment for all the versions of SQL Server we support in our production environment. Please advise.
