Looking for Upgrade Process of Windows 2003 32Bit to Windows 2008R2; but there is no process. As I searched and found 32 Bit 2003 OS cannot upgrade to Windows 2008 R2. Any Suggestion if I want to Upgrade the same server with 2008R2 ? Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
