I have the same question (0)You'll find a plenty of information on Technet: Upgrade to Microsoft Dynamics AX 2012.
Note that Axapta 3.0 is too old and it can't be directly upgraded to AX 2012, therefore you'll have to upgrade to AX 4.0 or AX 2009 first. I strongly recommend AX 2009, because you'll get better upgrade tools there.
