  • Hi,

    Looking at your situation, personally I felt is wise to go with server 2012. Because Microsoft have stop selling server 2008, unless you have legacy apps which requires 2008 edition to function. Then you may proceed to downgrade the server 2012 licenses to 2008 editions.

    Answers 1) How to decide what is better for 2008 or 2012 ?

    Answer 2) Is it possible to upgrade from 2003 to 2012 ?

    It's not possible to do this because Server 2003 is 32-bit and Server 2012 Essentials is 64-bit.  You MUST migrate to minimum 2008 R2 edition then proceed with upgrade from there, but you can certainly do that by virtualizing your current Server 2003 and then installing Server 2012 Essentials in Migration mode.

    Answer 3) AD 2003 function properly with AD 2012 ?
