SqlServer issues I've encountered or found on the interwebs:
* Microsoft SQL Server 2005 (the release version and service packs) and earlier versions of SQL Server are not supported on Windows Server 2012 or Windows 8. * SQL Server 2008 only runs on W2012 /Win8 from If you install R2. * Importing .bak files from SQL2005 to 2012 Express (Not sure about the full version) will not import. * Copying a database from SQL2005 to 2012Express in management studio will not work either. * SqlServer 2012 Will not run on Server 2003 * SQL Server 2012 requires a minimum of 6 GB of available hard-disk space. * SQL Server 2012 will not run on Server 2008, Vista, Win7 without a Service Pack
