http://msdn.microsoft.com/en-us/library/ms143393(v=sql.120).aspx (Supported Version and Edition Upgrades) seems to indicate that upgrade installs are okay but side-by-side installs are not:[quote]SQL Server 2014 supports upgrade from the following versions of SQL Server:SQL Server 2005 SP4 or laterThe table below lists the supported upgrade scenarios from earlier versions of SQL Server to SQL Server 2014.UPGRADE FROM SUPPORTED UPGRADE PATHSQL Server 2005 SP4 Standard SQL Server 2014 StandardAny scenarios not specified in the list above are not supported, including but not limited to the following:Installing SQL Server 2005 and SQL Server 2014 on same computer (side by side).[/quote]http://msdn.microsoft.com/en-us/library/ms143694(v=sql.120).aspx (Work with Multiple Versions and Instances of SQL Server) however clearly indicates that side-by-side installs are fine:[quote]You can install SQL Server on a computer that is already running instances of an earlier SQL Server version. If a default instance already exists on the computer, SQL Server must be installed as a named instance.The following table shows side-by-side support for SQL Server 2014:EXISTING INSTANCE OF SQL SERVER 2014 SIDE-BY-SIDE SUPPORTSQL Server 2014 (32-bit) SQL Server 2005 (32-bit)SQL Server 2005 (64-bit) x64SQL Server 2014 (64-bit) x64 SQL Server 2005 (32-bit)SQL Server 2005 (64-bit) x64[/quote]I'm also not sure if there's any significance to that text; where it refers to installing newer versions after older versions, in contrast to the heading titles that refer to "existing instance of 2014" which implies installing an older version after a newer one...Poor documentation, or my mistake?
