Which server exam is best to take. Server 2003 or Server 2012? I understand 2012 covers and is compatible with some of the new technologies but surely for most companies i would imagine they would not upgrade there servers yet until after a few years of testing.

Hi I can't know your problem correctly. exchange 2007 sp3 can be installed in windows 2008 r2 and windows 2012. exchange 2010 sp2 can be installed in windows 2008 r2 and windows 2012. If you don't want to install windows 2012. Windows 2008 R2 is the best choice.Terence Yu TechNet Community Support

Hi Thanks for your response. Let me make myself a little bit more clearer. Basically i was studying for MCSE exam 70-270, however it has now been changed and divided into three parts thus exam 70-410 to 412. The dilemma is that i had not even mastered server 2003 yet and now for the new exams they cover server 2012. Therefore i would like to know whether the changes introduced in server 2012 are that much that i would have to start studying for server 2012 from scratch or or there is still a lot of similarities eg windows server 2000 and 2003. Thanks
